By simulating conditions similar to those encountered in space, scientists are learning valuable lessons that will benefit future Mars missions and other long-duration spaceflights.

Submarine expeditions offer a unique opportunity to study the psychological and physiological effects of confinement and isolation. The SubSea project exemplifies this approach by having a diverse team of volunteers live underwater in a confined space for an extended period. This controlled environment mirrors the conditions that astronauts face during space missions, making it an ideal testbed for innovative research on human resilience.

Submarine Research as a Space Analog

Submarines have emerged as powerful analogs for space vehicles. In the SubSea project, participants experience a range of stressors—from limited physical space to the constant hum of machinery—that parallel the challenges encountered in orbit. The project’s success lies in its ability to recreate an environment where natural human responses to isolation can be observed and measured.

Researchers have noted that the confined submarine setting forces individuals to rely heavily on teamwork and adaptive coping strategies. The similarities between underwater and space conditions mean that lessons learned from submarine missions can be directly applied to planning for prolonged spaceflights. As a result, the SubSea project not only contributes to scientific knowledge but also serves as a training ground for future astronauts.

Research Methods and Data Collection

The comprehensive approach to data collection in the SubSea project is one of its greatest strengths. Researchers employed a variety of methods to track changes in both physical and mental health. Detailed questionnaires were administered at regular intervals, while biological samples, such as hair and saliva, were collected to monitor stress markers like cortisol. Continuous observation allowed scientists to document shifts in mood, cognitive function, and immune responses over the duration of the mission.

A detailed comparison of research parameters between underwater missions and space missions is presented in the table below:

Parameter	SubSea Project	Space Missions
Isolation Duration	60 days	6 months or longer
Number of Participants	25	3 to 6 astronauts
Data Collection	Questionnaires, saliva, hair	Medical tests, psychological surveys
Environmental Stress	Underwater confinement	Microgravity and radiation exposure

This table clearly illustrates how parameters from the SubSea project mirror those encountered during space missions, thus validating the use of submarine research as a simulation tool for space conditions.

Comparative Analysis of Environmental Conditions

Further emphasizing the connection between underwater and space environments, another table provides a side-by-side comparison of key environmental factors:

Environmental Factor	Underwater Conditions	Space Conditions
Gravity	Reduced buoyancy	Microgravity
Ambient Temperature	Stable and controlled	Extreme variations
Communication	Limited, with occasional delays	Signal delays due to distance
Physical Constraints	Confined space	Compact living quarters

This side-by-side comparison shows that both settings require individuals to adapt to limited physical space and altered environmental dynamics. Such parallels underscore the value of submarine research in preparing for the challenges of space travel.

Applications Beyond Space Missions

Although the primary goal of the SubSea project is to advance space exploration, the research has far-reaching implications. The methods and findings from this study can be adapted to improve conditions in other extreme environments, such as polar research stations and remote military bases. Innovations developed from understanding stress and isolation can also benefit mental health interventions on Earth, offering new strategies to combat depression, sleep disorders, and seasonal affective disorder.

Moreover, the lessons learned in underwater research can enhance safety protocols and operational strategies in various industries that operate in confined or high-risk settings. By bridging the gap between marine science and space exploration, researchers are opening new avenues for improving human performance and well-being in challenging circumstances.

Portugal’s Strategic Role and Global Impact

Portugal has positioned itself as a leader in analog research thanks to its unique combination of terrestrial and marine environments. With access to locations such as the Capelinhos Volcano and the Selvagens Islands, Portugal offers natural settings that simulate the harsh conditions of other planets. The collaboration between the European Space Agency (ESA), the Portuguese Space Agency, and the Portuguese Navy has resulted in pioneering projects like SubSea, which are critical for advancing our understanding of human adaptability.

This international cooperation not only enhances scientific discovery but also establishes Portugal as a strategic hub for future research initiatives. By leveraging its natural resources and expertise, Portugal is helping to shape the future of both marine and space exploration, creating a legacy of innovation and discovery.

Theia: The Impact That Brought Water to a Forming Earth

By Jonathan Bala February 7, 2025

Theia: The Impact That Brought Water to a Forming Earth

Water on Earth may have arrived in several late-stage events after the colossal impact of Theia, fundamentally reshaping our views on planetary formation and the origin of life.

Summary

Theia Impact: A Mars-sized body collided with early Earth, initiating the Moon’s formation.
Water Delivery Mechanism: Instead of a single event, water arrived in small doses through later accretion processes involving asteroids and comets.
Scientific Insights: Isotopic analysis of meteorites and terrestrial rocks has provided new clues on where Earth’s building blocks originated.
Collaborative Research: Multiple institutions have contributed to advancing our understanding of Earth’s formation, including work by Rutgers University and other renowned centers.
Life’s Foundations: The timing and nature of water delivery are pivotal for the emergence and evolution of life on Earth.

Theia The Impact That Brought Water to a Forming Earth — This is a picture created by an artist. It shows a huge collision that changed the Earth. This collision also made the Moon. Credit for the image goes to NASA and JPL-Caltech.

Introduction

The early history of our planet is a tale of cosmic collisions and miraculous deliveries. Among the most dramatic events in Earth’s history is the collision with a Mars-sized body known as Theia. This colossal impact not only resulted in the formation of the Moon but also set the stage for the arrival of water on Earth. Over billions of years, water has played a crucial role in shaping the planet’s geology and the development of life. Researchers continue to study this event to unravel the mysteries behind the origins of our world.

The widely accepted theory suggests that shortly after the birth of the Sun from a swirling nebula, the remaining dust and gas formed a protoplanetary disk. Within this disk, various celestial bodies began to coalesce under gravity. Theia emerged as one of these bodies, and its eventual collision with early Earth marked a turning point in the planet’s evolution.

The Theia Impact Event

In the tumultuous environment of the early Solar System, collisions were common. Theia, a protoplanet approximately the size of Mars, is believed to have struck the early Earth around 4.5 billion years ago. This violent impact ejected vast amounts of material into orbit around Earth, which eventually coalesced to form the Moon. The repercussions of this event were profound. Not only did the collision dramatically alter Earth’s rotation and structure, but it also created conditions that may have allowed water and other volatile compounds to accumulate.

The aftermath of the impact created a dynamic stage for cosmic events that followed. Scientists used to believe that the Moon-forming impact brought most of Earth’s water. However, new research shows this might not be true. Water may have arrived on Earth in a later phase. This later period involved several small impacts. Water-rich asteroids and comets hit the young planet. These impacts brought essential elements like water to Earth.

Water Delivery to a Forming Earth

Water is the cornerstone of life, and understanding how it arrived on Earth is essential to the field of planetary science. Recent studies, including those published on ScienceDirect, suggest that the bulk of water did not come from the initial Theia impact. Instead, the planet received water in smaller increments during the late stages of its formation—a phase known as late accretion.

The prevailing theory is that after the Moon had formed, a series of smaller impacts delivered water to Earth. Research featured in Rutgers News highlights how isotopic studies of meteorites and terrestrial rocks have provided evidence for this process. Scientists, including experts such as Katherine Bermingham, have analyzed the isotopic composition of elements like molybdenum. Their work shows that the chemical signatures in Earth’s rocks more closely resemble those found in meteorites from the inner Solar System rather than those from the outer regions where water and volatiles are more common.

A key discovery was made when comparing the isotopic ratios of molybdenum in meteorite samples from institutions like the Smithsonian National Museum of Natural History with those measured in rocks from various parts of the globe. These findings provide a compelling case that the water present on our planet arrived in stages rather than in a single, dramatic event.

Scientific Investigations

Researchers from diverse institutions, such as Rutgers University and PhAB at the University of Oslo, have worked together to decode the early history of water on Earth. Their investigations involve detailed isotopic analyses and comparisons of extraterrestrial materials. A significant portion of this research centers on understanding the non-carbonaceous nature of late-stage accretion, a subject discussed in a paper published in Geochimica et Cosmochimica Acta.

This insight highlights the importance of knowing both when water was delivered and how it was delivered. Scientists compared data from meteorites with samples from Earth. They collected these Earth samples from places like Greenland, South Africa, Canada, the United States, and Japan. They all agreed from these studies that Earth’s water came after the Moon was formed. This idea challenges what people thought before.

Data and Timeline

Below are two tables that help illustrate the timeline of events and the comparative isotopic signatures that support the late accretion theory.

Table 1: Timeline of Theia Impact and Water Delivery

Event	Time (Billion Years Ago)	Description
Formation of the Sun	4.6	The Sun forms from the collapse of a giant molecular cloud.
Theia Impact	4.5	A Mars-sized body collides with Earth, leading to the Moon’s formation.
Late Accretion Phase	4.4 – 4.3	Smaller impacts deliver water and other volatiles to the Earth after the Moon has formed.
Stabilization of Earth	4.3	Earth’s environment becomes more conducive to the emergence of life.

Table 2: Comparison of Isotopic Signatures

Sample Type	Isotopic Signature	Source Region
Inner Solar System Rocks	Enriched in specific isotopes	Formed close to the Sun
Meteorites (NC group)	Similar to Earth’s rocks	Originated from the drier inner Solar System
Meteorites (CC group)	Higher volatile content	Formed in the outer Solar System

Implications for Life

The timing of water delivery is critical when considering the origins of life on Earth. Water, along with energy and essential chemical building blocks, set the stage for biochemical processes that eventually led to life. The notion that water arrived in small increments during late accretion implies that Earth’s habitability developed over an extended period rather than as a sudden consequence of the Theia impact.

The introduction of water was gradual. This process led to more complex geochemical interactions. Geochemical interactions are chemical reactions between the Earth’s crust and other elements like water. These interactions might have created a stable environment. In such an environment, organic molecules could form and change over time. Organic molecules are basic building blocks of life. The research challenges what we assumed before. It also offers new possibilities for finding life on other planets. As we explore exoplanets, understanding Earth’s early history becomes even more important. Exoplanets are planets outside our solar system that might host life.

Fun Facts

Theia was named after a Titaness in Greek mythology, reflecting its monumental role in shaping the Earth.
The Moon is the fifth largest natural satellite in the Solar System.
Late accretion is a process observed on other planets and moons, highlighting common themes in planetary evolution.
Isotopic analysis is a powerful tool that helps scientists trace the origins of materials in the Solar System.

Introduction

In our modern era of advanced space observation, the discovery of near-Earth objects is not only a scientific milestone but also a crucial element of planetary safety. The recent detection of Asteroid 2024 YR4 has once again captured global attention, emphasizing that even relatively small celestial bodies can command international focus. This event is a reminder of our planet’s vulnerability in a vast universe and the need for a proactive stance in space monitoring. As scientists work to decode the asteroid’s trajectory, the incident serves as an educational moment about the complexities of cosmic surveillance and the coordinated response required when potential hazards are identified.

Discovery and Detection

On December 27, 2024, a routine scan of the night sky over Chile led to the detection of Asteroid 2024 YR4. This discovery was made possible by state-of-the-art automated telescopes designed to capture faint objects moving against the static backdrop of distant stars. The initial images revealed a fast-moving object, prompting immediate follow-up observations by astronomers worldwide.

The detection process involves advanced image processing and pattern recognition algorithms that can distinguish a moving asteroid from other celestial objects. Over the following weeks, scientists have been meticulously analyzing the data to calculate the asteroid’s orbit and velocity. The early indications show that the object, with an estimated diameter of about 100 metres, is on a path that brings it close to Earth. Although the calculated impact probability stands at 1.3% for an encounter in December 2032, further observations are essential to narrow down these predictions and either confirm or allay any concerns.

Impact Risk Assessment

Assessing the risk posed by near-Earth objects requires a deep understanding of several parameters, including size, speed, and trajectory. In the case of Asteroid 2024 YR4, experts have applied the NASA Torino Impact Hazard Scale to gauge the level of threat. This scale, which ranges from 0 (no risk) to 10 (certain collision with catastrophic consequences), is a standard tool used by scientists to communicate risk levels in a clear and accessible manner.

Currently, 2024 YR4 is rated as a Level 3 threat. This means that although the likelihood of an impact is extremely low, the uncertainty in its orbital path necessitates careful and ongoing observation. The Torino scale not only factors in the probability of impact but also considers the potential consequences of such an event. With a size of around 100 metres, an impact would not lead to a mass extinction like the one that wiped out the dinosaurs, but it could cause severe localised damage, particularly if the collision occurs over a densely populated area.

Over time, as more data is gathered and computational models are refined, scientists expect to adjust the risk rating. The current approach is one of caution—an acknowledgment that even a 1.3% chance is significant enough to merit continued surveillance.

International Response and Coordination

Upon confirmation of the initial observations, global authorities quickly activated a series of planetary defense protocols. Key organizations such as the International Asteroid Warning Network and the Space Mission Planning Advisory Group have mobilized to assess the situation further. These agencies are responsible for coordinating the observation efforts, sharing data across borders, and preparing strategies for potential intervention.

The global response reflects a blend of urgency and prudence, ensuring that all necessary resources are directed toward monitoring and analysis without inducing public panic. International coordination in such scenarios has proven invaluable, as shared expertise and technological capabilities enhance the accuracy of predictions and the feasibility of any needed intervention.

The mechanisms in place today benefit from decades of prior experience with asteroid threats. Past events, such as the reclassification of Asteroid Apophis, have laid the groundwork for a robust international system capable of rapidly responding to emerging cosmic hazards.

Asteroid 2024 YR4 Key Characteristics

The following table summarizes the essential data regarding Asteroid 2024 YR4:

Feature	Value
Estimated Diameter	Approximately 100 metres
Discovery Date	December 27, 2024
Impact Probability	1.3% chance of collision on December 22, 2032
Torino Scale Rating	3
Last Observed	January 2025
Next Observation Window	Expected in 2028

This concise presentation of the asteroid’s characteristics helps both experts and the general public grasp the scale of the potential threat. It is a snapshot of current scientific understanding and an indication of the ongoing efforts to monitor the object.

Comparative Analysis of Notable Asteroid Encounters

To better understand the significance of Asteroid 2024 YR4, it is useful to compare it with other well-known near-Earth objects. One notable case is Asteroid Apophis, which in 2004 received worldwide attention due to its initially high risk of impact. Although subsequent observations led to a downgrade in its threat level, Apophis remains a benchmark in discussions about asteroid impact risk.

Asteroid	Estimated Size	Initial Torino Rating	Current Impact Risk	Notable Missions/Responses
2024 YR4	Approximately 100 metres	3	1.3% chance of impact	Continuous monitoring, potential deflection planning
Apophis	Approximately 370 metres	4 (later downgraded)	Minimal after reassessment	Extensive global monitoring and research

This table clearly compares the relative danger of these objects. It helps us understand how dangerous they are. Apophis, a large asteroid, first caused a lot of alarm. It seemed more threatening because it was big and had a high rating. However, scientists used better ways to observe it. These new techniques reduced how threatening Apophis seemed. Another asteroid, 2024 YR4, is smaller. Despite its size, it still needs attention. This is because there are uncertainties about its path in space. The word “orbit” means the path an object like an asteroid takes as it moves around in space.

Technological and Observational Strategies

Modern astronomy relies on an array of sophisticated technologies to detect and track near-Earth objects. The automated telescope in Chile, responsible for spotting 2024 YR4, is just one example of these cutting-edge instruments. Equipped with high-resolution sensors and advanced image processing capabilities, these telescopes can detect even the faintest objects in the sky.

Once an object is detected, data is immediately transmitted to research centers around the world where it is processed using complex computer models. These models calculate the object’s orbital parameters and simulate future trajectories based on gravitational influences and other factors. This process is critical for determining whether an object poses a significant threat to Earth.

In addition to optical telescopes, radar systems and space-based sensors also contribute to the detection and tracking of asteroids. The integration of data from multiple sources ensures that predictions are as accurate as possible. The advancements in computational modeling, in particular, have revolutionized the way scientists predict the paths of near-Earth objects, providing a robust framework for assessing impact risk.

Another significant technological development is the capacity to test asteroid deflection methods in controlled environments. NASA’s DART mission is an excellent example of how kinetic impact techniques can be employed to alter an asteroid’s trajectory. Although 2024 YR4 is not currently expected to hit Earth, the knowledge gained from these experiments could prove invaluable if a deflection is ever required.

Future Monitoring and Preparedness

Given the current uncertainties in the trajectory of Asteroid 2024 YR4, continuous monitoring is of utmost importance. Future observation windows, particularly the next opportunity in 2028, will be critical in providing more accurate data on the asteroid’s path. Astronomers are preparing a series of coordinated observation campaigns to track even the smallest deviations in its orbit.

The international scientific community is committed to refining predictive models and improving detection technologies. By pooling resources and expertise, countries are working together to establish a more comprehensive planetary defense network. This network will not only focus on 2024 YR4 but will also enhance our overall capacity to detect and analyze other near-Earth objects.

In parallel, simulation exercises and scenario planning are underway to prepare for a range of potential outcomes. These initiatives are designed to ensure that if a mitigation strategy becomes necessary, the global community can respond swiftly and effectively. The proactive measures being implemented today are a testament to the lessons learned from past encounters with celestial objects and the ongoing evolution of space defense strategies.

Even though the probability of an impact by Asteroid 2024 YR4 is low, scientists are not leaving any stone unturned when it comes to potential mitigation strategies. One of the primary methods under consideration is asteroid deflection. This approach involves altering the trajectory of the asteroid so that it misses Earth entirely.

One deflection method is the kinetic impactor technique, where a spacecraft is intentionally crashed into the asteroid at high speed. The impact, though not large enough to destroy the asteroid, would be sufficient to change its course over time. Another promising method is the gravity tractor, which involves positioning a spacecraft near the asteroid. The gravitational pull between the two bodies, though subtle, can gradually alter the asteroid’s path if maintained over a prolonged period.

The timeline for any deflection operation is critical. Early detection allows for a more extended window in which a mitigation strategy can be implemented. This is why continuous tracking and frequent observations are so essential. International agencies are discussing how best to coordinate these potential operations, ensuring that if an intervention is necessary, it can be executed with minimal risk to Earth.

Advancements in simulation technologies are also playing a crucial role in preparing for any eventuality. By running countless scenarios using supercomputers, scientists can model the outcomes of different deflection strategies and choose the most effective one. This proactive approach to planetary defense is one of the most encouraging developments in space science today.

Fun Facts

Asteroid impacts have played a significant role in shaping Earth’s geological and biological history.
Modern telescopes can now detect objects that are only a few metres in diameter.
Planetary defense strategies have evolved significantly since the days when asteroid impacts were only a theoretical threat.
International collaboration in space research has increased exponentially in recent years.
Public interest in asteroid monitoring has grown, with many space agencies now hosting live updates on their websites.

Future studies aim to use asteroseismology to explore matter at varying densities within neutron stars.

Transforming Nuclear Physics Through the Study of Neutron Starquakes

Introduction

Neutron stars are among the most fascinating objects in the universe. Born from the explosive deaths of massive stars, these remnants are incredibly dense, packing the mass of a star into a sphere roughly the size of a city. The extreme conditions within neutron stars make them ideal laboratories for studying nuclear matter under conditions that cannot be replicated on Earth.

Recent research led by the University of Bath has focused on a phenomenon known as starquakes—seismic activities within neutron stars. These starquakes, studied through a field called asteroseismology, provide valuable data about the internal structure and behavior of neutron stars. This research has the potential to transform our understanding of nuclear physics and its applications in various fields.

The Significance of Neutron Stars

Neutron stars are the remnants of massive stars that have exhausted their nuclear fuel and collapsed under their own gravity. This collapse results in an object so dense that a single teaspoon of neutron star material would weigh billions of tons on Earth.

The extreme density of neutron stars means that the matter within them exists in states that cannot be replicated in terrestrial laboratories. This makes neutron stars invaluable for testing theories about nuclear matter, such as Chiral Effective Field Theory, which seeks to explain the interactions between protons and neutrons in extreme conditions.

What Are Starquakes?

Starquakes are seismic events that occur on the surface of neutron stars, analogous to earthquakes on Earth. These quakes are caused by the immense gravitational forces and magnetic fields present in neutron stars. When the crust of a neutron star cracks or shifts, it releases energy in the form of vibrations and flares, which can be detected by telescopes on Earth.

Studying these starquakes through asteroseismology allows scientists to probe the internal structure of neutron stars. By analyzing the frequencies and patterns of these vibrations, researchers can infer details about the density, composition, and behavior of matter within the star.

Bridging Nuclear Physics and Astronomy

Traditionally, nuclear physics and astronomy have been separate fields of study. However, the research led by the University of Bath demonstrates how these disciplines can intersect. By using asteroseismology to study neutron stars, scientists can test and refine theories about nuclear matter that are difficult to explore through Earth-based experiments.

Transforming Nuclear Physics Through the Study of Neutron Starquakes

Applications of Neutron Star Research

The insights gained from studying neutron starquakes have far-reaching implications beyond astrophysics. Here are some key areas where this research could make a difference:

Health

With its ability to map the universe in 102 infrared colors, SPHEREx aims to provide insights into cosmic phenomena such as the inflationary period after the Big Bang, the distribution of galaxies, and the presence of life’s building blocks like water and carbon dioxide. This mission will complement existing space telescopes like Hubble and Webb by providing broad-spectrum data, which will enable more detailed observations of identified objects. SPHEREx’s contributions will shape our understanding of both the cosmic past and future, making it one of the most significant space exploration endeavors to date.

Summary

SPHEREx Telescope will provide comprehensive infrared maps of the entire sky, observing more than 450 million galaxies.
It will study cosmic inflation, a key moment in the universe’s expansion after the Big Bang, enhancing our understanding of large-scale universe structure.
The telescope will help to measure the total glow from all galaxies, including distant, faint, or small ones, filling in gaps left by previous observations.
SPHEREx will search the Milky Way galaxy for essential molecules like water ice and carbon dioxide in regions where stars and planets are forming, offering clues about the origin of life.
The observatory will use spectroscopy to create the most colorful all-sky map ever, giving a 3D visualization of galaxies and the chemical compounds within them.
SPHEREx’s cone-shaped design will keep it cold enough to detect faint infrared signals, using a passive cooling system to protect the instruments.

Introduction to SPHEREx

The SPHEREx mission is one of NASA’s most anticipated space telescopes set to revolutionize our understanding of the universe. Slated for launch on February 27, 2025, from Vandenberg Space Force Base, this observatory will be unlike any other, mapping the entire celestial sky in 102 infrared colors. Its mission is focused on exploring the origins of the universe, the formation of galaxies, and the essential ingredients of life, such as water ice and carbon dioxide, found in the Milky Way. To fully appreciate the significance of this mission, let’s dive into six essential facts about SPHEREx.

1. SPHEREx Will Shed Light on Cosmic Inflation

One of the most intriguing phenomena that SPHEREx will help unravel is cosmic inflation—a brief but critical period in the early universe. In the first billionth of a trillionth of a trillionth of a second after the Big Bang, the universe expanded rapidly by a trillion-trillionfold, reaching its current size. This inflationary period set the foundation for the large-scale distribution of matter we observe in the universe today.

By mapping more than 450 million galaxies, SPHEREx will provide a detailed look at this cosmic event, helping scientists understand the physics that caused the universe to grow at such a mind-boggling rate. The spatial distribution of galaxies mapped by SPHEREx will offer critical clues to the underlying mechanics of inflation and give us insight into how the early universe evolved.

This will be the first time an observatory has provided such a comprehensive map of cosmic inflation, laying the groundwork for future research in cosmology.

2. The Observatory Will Measure the Collective Glow from Galaxies

Previous efforts to estimate the total light output of all galaxies in the universe have been based on observations of individual galaxies. However, many galaxies are too small, too faint, or too distant to be observed by current telescopes. SPHEREx is designed to take a novel approach: instead of observing individual galaxies, it will measure the combined glow from all galaxies. This will offer a more complete picture of the universe’s cosmic light, from the very first stars to present-day galaxies.

This comprehensive measurement will help fill gaps in our knowledge, as it includes the light emitted by galaxies that previous telescopes like Hubble and Webb may have missed. The total light output measured by SPHEREx will allow scientists to better understand the evolution of galaxies and their role in the universe’s broader illumination.

3. Searching for Life’s Building Blocks in the Milky Way

One of the most exciting aspects of SPHEREx’s mission is its ability to search for the key ingredients for life, such as water ice and carbon dioxide, in the Milky Way galaxy. These molecules are found in cold interstellar clouds of gas and dust, which are star-forming regions where planets can also form. Without these basic compounds, life as we know it would not be possible.

Using its infrared spectroscopy, SPHEREx will identify and map the locations and abundance of these molecules across the galaxy. This will provide valuable insight into the potential for life in other star systems, particularly in planets that may be forming in regions rich in these vital elements.

By mapping molecular clouds like Rho Ophiuchi, SPHEREx will advance our understanding of the conditions required for life to form, allowing scientists to further explore the possibility of life beyond Earth.

4. SPHEREx Adds Unique Strengths to NASA’s Space Telescope Fleet

NASA already boasts advanced space telescopes such as Hubble and Webb, which have provided stunning images and valuable data about distant galaxies, stars, and planets. However, these telescopes have focused on observing individual objects at high resolution. SPHEREx, on the other hand, is designed to capture the big picture—mapping the entire sky in infrared wavelengths.

With its ability to provide an all-sky view, SPHEREx complements existing telescopes by identifying objects of interest for more targeted investigations. After SPHEREx maps the sky, telescopes like Hubble and Webb can zoom in on specific targets for deeper analysis. This partnership between SPHEREx and other space telescopes will create a comprehensive view of the universe.

5. The Most Colorful All-Sky Map Ever

SPHEREx will create the most colorful all-sky map in history. Using infrared light, which is invisible to the human eye, the observatory will capture wavelengths that are ideal for studying stars, galaxies, and other cosmic objects. Through spectroscopy, SPHEREx will split light into its component colors, much like a prism splits sunlight into a rainbow.

This will allow scientists to analyze the chemical composition of distant galaxies and stars, measure their distances, and even track the history of the universe’s light output. The resulting map will provide a 3D representation of the cosmic structure and help us understand how the universe has evolved over billions of years.

6. The Cone-Shaped Design Helps It Stay Cold and See Faint Objects

SPHEREx’s design incorporates a passive cooling system to keep the spacecraft’s infrared detectors at temperatures as low as -350°F (around -210°C). This is necessary to prevent the telescope from emitting its own infrared light, which could overwhelm the faint signals from distant cosmic objects.

The spacecraft’s unique cone-shaped design helps protect the telescope from heat by blocking sunlight and the warmth of Earth. The photon shields, which are part of this design, keep the telescope cool and allow it to operate at optimal conditions, ensuring it can detect even the faintest of cosmic signals.

The SPHEREx space telescope represents a massive leap forward in our understanding of the universe. By mapping the entire sky in 102 infrared colors, SPHEREx will help solve some of the most fundamental questions in cosmology, astronomy, and the search for life beyond Earth. It will complement existing space observatories by providing large-scale data that can guide more detailed studies of individual objects, thus contributing to a holistic understanding of the cosmos.

The telescope’s unique ability to observe cosmic inflation, measure the collective glow of galaxies, and search for the building blocks of life in the Milky Way, will add essential pieces to the puzzle of our universe’s history and its potential for sustaining life.

Fusion energy has remained an elusive goal for decades. While nuclear fission is widely used in power plants, fusion—the process that powers the Sun—has proven far more difficult to harness. However, a new breakthrough involving the Small Aspect Ratio Tokamak (SMART) could bring us significantly closer to achieving practical nuclear fusion.

Developed by the University of Seville’s Plasma Science and Fusion Technology Laboratory, SMART recently achieved its first plasma, marking an important milestone in fusion research. Unlike conventional tokamaks, SMART explores the concept of negative triangularity, a unique plasma configuration that could solve one of the biggest hurdles in fusion energy: plasma stability.

𝑻𝒐𝒌𝒂𝒎𝒂𝒌𝒔: 𝑨 𝑪𝒓𝒖𝒄𝒊𝒂𝒍 𝑺𝒕𝒆𝒑 𝑻𝒐𝒘𝒂𝒓𝒅𝒔 𝑬𝒏𝒆𝒓𝒈𝒚 𝑰𝒏𝒅𝒆𝒑𝒆𝒏𝒅𝒆𝒏𝒄𝒆

Tokamaks are donut-shaped reactors designed to contain and stabilize super-heated plasma using powerful magnetic fields. The challenge with these devices has always been controlling instabilities that can disrupt fusion reactions.

Traditionally, plasma in tokamaks has a positive triangularity—meaning the “D”-shaped plasma has its curved edge facing outward. However, scientists have discovered that flipping this configuration to negative triangularity can suppress dangerous instabilities such as Edge Localized Modes (ELMs). These instabilities can damage reactor walls and make sustained fusion reactions difficult.

SMART is the first compact tokamak specifically designed to test negative triangularity on a practical level. If successful, this approach could significantly improve plasma confinement and make fusion energy more viable and cost-effective.

SMART is more than just a scientific experiment; it is a core component of the Fusion2Grid strategy at the University of Seville. This initiative aims to develop grid-based fusion energy as a practical alternative to fossil fuels.

The success of SMART could help design compact, high-performance fusion reactors that are both affordable and scalable. Unlike massive fusion projects such as ITER, SMART’s compact nature allows for faster development cycles and lower costs.

Lunar Surfaces: Evidence of Recent Geological Activity on the Moon

By Jonathan Bala February 1, 2025

Lunar Surfaces: Evidence of Recent Geological Activity on the Moon

The Moon was previously thought to be geologically inactive, but new research suggests that it still experiences tectonic activity. Recent studies reveal small ridges on the lunar surface, formed in the last 200 million years, indicating ongoing geological processes. Understanding these features is crucial for future lunar exploration and potential astronaut missions.

𝐒𝐮𝐦𝐦𝐚𝐫𝐲

The Moon likely formed from a giant impact between Earth and a Mars-sized object called Theia.
Evidence from Apollo missions and seismic studies suggests the Moon once had a magnetic field and volcanic activity.
The Moon’s volcanic activity was thought to have ended about 3 billion years ago, making it geologically dead.
A recent study by the National Air and Space Museum (NASM) and the University of Maryland (UMD) challenges this view.
Researchers found small ridges on the Moon’s far side that are younger than those on the near side.
These ridges likely formed in the last 200 million years due to ongoing tectonic forces.
A technique called crater counting helped determine the ridges’ age.
The ridges may have been caused by moonquakes, which result from shifts in the Moon’s orbit and gradual shrinkage.
Apollo missions first detected moonquakes, but their significance has only recently been understood.
New discoveries suggest the Moon remains geologically active, affecting future lunar missions.
Future missions should use ground-penetrating radar to study subsurface structures.
Scientists aim to determine how these ridges formed and if tectonic activity is still occurring.
Findings impact plans for Moon bases, affecting astronaut safety and infrastructure placement.
Understanding lunar geology helps in designing equipment for long-term Moon exploration.
The research was published in the Planetary Science Journal, with contributions from multiple institutions.

𝐆𝐢𝐚𝐧𝐭 𝐈𝐦𝐩𝐚𝐜𝐭 𝐇𝐲𝐩𝐨𝐭𝐡𝐞𝐬𝐢𝐬 𝐚𝐧𝐝 𝐌𝐨𝐨𝐧’𝐬 𝐅𝐨𝐫𝐦𝐚𝐭𝐢𝐨𝐧

The Giant Impact Hypothesis suggests that the Moon formed around 4.5 billion years ago from debris after a massive collision between Earth and a Mars-sized object, Theia. This theory is supported by Apollo mission rock samples, which show similarities between Earth and Moon compositions. Seismic studies further confirm their shared history.

𝐋𝐮𝐧𝐚𝐫 𝐒𝐮𝐫𝐟𝐚𝐜𝐞 𝐅𝐞𝐚𝐭𝐮𝐫𝐞𝐬 𝐚𝐧𝐝 𝐕𝐨𝐥𝐜𝐚𝐧𝐢𝐬𝐦

Early observations suggested that the lunar maria—dark, flat regions on the Moon—formed due to volcanic activity billions of years ago. Scientists believed the Moon’s volcanic activity ended around 3 billion years ago, leaving it geologically inactive.

𝐍𝐞𝐰 𝐄𝐯𝐢𝐝𝐞𝐧𝐜𝐞 𝐨𝐟 𝐑𝐞𝐜𝐞𝐧𝐭 𝐀𝐜𝐭𝐢𝐯𝐢𝐭𝐲

A study by NASM and UMD found small ridges on the Moon’s far side that are younger than previously thought. These ridges, formed within the last 200 million years, suggest that the Moon is still tectonically active.

According to lead researcher Cole Nypaver, these ridges align in groups of 10 to 40, possibly formed over weak spots in the lunar crust. Using crater counting, scientists estimated their age and concluded that some ridges formed in the last 160 million years.
