Exploring Mars’ Ancient Past

Mars, often called the “Red Planet,” has long intrigued scientists due to its potential to harbor water and perhaps even life in its early days. Studies comparing Earth and Mars suggest that their histories initially aligned. Over 4 billion years ago, both planets featured warm oceans, dynamic weather systems, and volcanic activity. However, the divergent fates of these celestial siblings pose a mystery.

Mars’ clay-covered surface provides indirect evidence of water cycles during the Noachian period (4.1 to 3.7 billion years ago) and subsequent Hesperian flows. However, what happened before this period—the pre-Noachian era—is largely unknown. Recent breakthroughs, including the analysis of Martian meteorites, have revealed new chapters in the planet’s history.

Black Beauty: A Martian Treasure

One of the most important pieces in the puzzle is Northwest Africa 7034, commonly referred to as Black Beauty. Found in 2011 in the Western Sahara desert, this meteorite dates back 4.4 billion years and contains significant amounts of water.

Black Beauty’s zircon crystals offer unique insights into Mars’ earliest era. These tiny crystals, aged 4.48 to 4.43 billion years, display patterns of oscillatory zoning—a rare geological feature. On Earth, such formations occur only in hydrothermal systems, such as Yellowstone National Park’s geysers.

Hydrothermal Systems and the Origins of Life

Hydrothermal activity on early Mars reveals striking parallels with Earth’s conditions. Geysers and thermal vents on Earth have been identified as potential cradles for life due to their nutrient-rich waters and geothermal energy. Could Mars have hosted similar ecosystems?

The discovery of hydrothermal systems during Mars’ pre-Noachian period indicates the presence of warm, circulating water. This environment could have created the perfect setting for organic molecules—key building blocks of life—to form.

A Geological Comparison: Earth vs. Mars

Aspect	Earth	Mars
Water Cycle	Stable for 4.5 billion years	Interrupted; water mostly evaporated or froze
Hydrothermal Activity	Found in geysers and oceanic ridges	Confirmed during the pre-Noachian period
Magnetic Field	Strong, protecting the atmosphere	Weak; lost over time, contributing to water loss
Surface Evidence of Water	Oceans, rivers, lakes	Ancient riverbeds, clay minerals

Why Did Mars Dry Out?

Unlike Earth, which retained its water due to a robust magnetic field and higher gravity, Mars faced unique challenges:

Weak Magnetic Field: Without a strong magnetic field, solar winds stripped Mars of its atmosphere.
Low Gravity: Mars’ gravity was insufficient to retain liquid water on the surface.
Climate Shift: Mars experienced a significant cooling phase, freezing most of its water reserves.

These factors transformed Mars from a warm, oceanic planet to the barren landscape we observe today.

Potential for Ancient Life on Mars

The presence of warm, hydrothermal systems raises intriguing questions about Mars’ potential to support life. Early Earth’s lifeforms thrived in similar environments, suggesting a possibility that life may have briefly flourished on ancient Mars.

Feature Supporting Life	Mars Evidence
Water Availability	Clay minerals, ancient flows
Energy Sources	Hydrothermal vents
Organic Molecules	Potential precursors in meteoric studies

Mars vs. Earth: Two Divergent Worlds

Despite their similar beginnings, Mars and Earth followed vastly different paths. Earth’s stable water cycle and protective atmosphere fostered a biosphere teeming with life. Mars, however, lost its water and became a cold desert.

The findings from Black Beauty and other meteorites highlight the importance of Mars exploration missions. NASA’s Perseverance rover and the European Space Agency’s Rosalind Franklin rover aim to uncover further evidence of water and past life.

Advancements in technology, such as in-situ sample analysis and potential Mars sample return missions, could provide definitive answers about Mars’ ancient oceans and their role in shaping the planet’s history.

Fun Fact:

Did you know that Mars has the largest volcano in the solar system? It is named Olympus Mons. This volcano is 13.6 miles high. That is very tall. This huge volcano shows that Mars had a fiery start. Geological activity means changes in a planet’s surface, like when a volcano erupts.

Mars’ surface temperature averages -80°F (-60°C), making it inhospitable for liquid water today.

Supercomputer Simulation Explains the Origins of Mars’ Moons

By Jonathan Bala November 24, 2024

Supercomputer Simulation Explains the Origins of Mars’ Moons

Mars’ moons, Deimos and Phobos, have long been mysterious. While various theories have existed about their origins, new supercomputer simulations are providing fresh insights. These simulations suggest that the moons were not simply captured asteroids, nor the result of a traditional collision. Instead, a near miss by a large asteroid may have created a debris ring from which the moons formed.

This discovery brings us closer to understanding these enigmatic companions of Mars. With future missions like the Mars Moons eXploration (MMX) mission set for 2026, we may finally answer the question of how Mars’ moons came to be.

Summary

Mars is one of only two rocky planets in the solar system with moons.
The two Martian moons, Deimos and Phobos, resemble small asteroids.
There are two main models explaining their origins: capture or collision.
The capture model struggles due to Mars’ weak gravity.
The collision model suggests an asteroid impact, forming debris that became the moons.
A new model proposes a “near miss” by an asteroid that caused tidal forces to break it apart.
The fragments from the near miss formed elliptical orbits around Mars, eventually becoming circular.
The new model explains the orbital characteristics of both moons.
The upcoming MMX mission in 2026 may provide rock samples to confirm the origin.

Introduction to the Mystery of Mars’ Moons

Mars’ moons, Deimos and Phobos, have fascinated scientists for centuries. Unlike Earth’s Moon, which has a well-understood origin tied to the collision between Earth and a protoplanet, Mars’ moons have remained enigmatic. While these moons are small, irregularly shaped objects, they hold critical clues about the early history of our solar system and the planet Mars itself. Researchers have proposed several theories about how these moons were formed, but new advancements in supercomputer simulations are helping to clarify their true origin.

The Current Models

Two main theories have dominated discussions about the origins of Deimos and Phobos.

Capture Theory:

This theory suggests that the moons are captured asteroids. This would explain why they resemble asteroids in size and composition. However, this model faces significant challenges because Mars is much smaller than Earth and Venus, and its gravitational pull is weaker. Capturing one asteroid, let alone two, would be a rare event, especially for a planet like Mars. In addition, captured moons generally have elliptical orbits, which does not match the nearly circular orbits of Phobos and Deimos.

Collision Theory:

The collision theory posits that an asteroid or comet collided with Mars early in its history. This impact would have created a debris ring, and from this ring, the moons would have formed. This theory accounts for the circular orbits of Phobos, which is close to Mars. However, Deimos, the smaller moon, has a more distant orbit, which is difficult to explain using this theory.

The Supercomputer Simulation Breakthrough

New supercomputer simulations are challenging these traditional models by proposing a compromise theory that blends both ideas. According to this new model, a large asteroid passed close to Mars and was torn apart by the tidal forces of the planet’s gravity. Instead of being captured outright or colliding with Mars, the asteroid’s fragments were captured into elliptical orbits around Mars. Over time, these orbits shifted due to the small gravitational influences of the Sun and other planets in the solar system.

The small gravitational tugs from other bodies, including the Sun, caused the orbits of the fragments to shift, eventually leading some of them to collide and form a debris ring around Mars. This process allowed the moons to form at a greater distance than the collision model had suggested, better explaining both the orbits of Phobos and Deimos.

This breakthrough offers a better explanation for the current positions and orbits of the Martian moons. It accounts for the proximity of Phobos to Mars and the more distant orbit of Deimos.

The Importance of the MMX Mission

While these simulations offer an intriguing explanation, they are still hypotheses. The real test will come in 2026, when the Mars Moons eXploration (MMX) mission is set to launch. MMX will explore both Deimos and Phobos, gathering important samples, particularly from Phobos, to help confirm or challenge these theories. This mission could be the key to unlocking the mystery of how Mars’ moons came to be.

Facts About Mars’ Moons

Phobos is gradually getting closer to Mars and will eventually crash into the planet in about 50 million years.
Deimos is moving away from Mars at a rate of about 1.8 centimeters per year.
The origin of Mars’ moons has been debated for centuries, but we are now closer to solving the mystery.
Both moons are irregularly shaped and are considered to be captured asteroids or remnants from a past collision.
The name Phobos comes from the Greek word for “fear,” while Deimos comes from the Greek word for “panic.” These names were chosen because of the moons’ association with Mars, the god of war.

The origins of Mars’ moons have long been a topic of great scientific interest. Through new supercomputer simulations, researchers are offering a compelling new theory that might finally explain the mysteries of Deimos and Phobos. Whether these moons were captured from the asteroid belt or the result of a near-miss asteroid collision, the answers will likely come in the near future with the MMX mission. Until then, the mystery of Mars’ moons remains an exciting puzzle for scientists and space enthusiasts alike.

Tree rings and ice cores provide complementary records of these events.
The Sun’s most powerful solar storms, called Solar Particle Events (SPEs), have occurred multiple times over the past 14,500 years.
SPEs can disrupt communication systems, power grids, and space missions.
The 660 BCE Miyake Event is a key example of a double-pulsed SPE with unique characteristics.
Carbon-14 in tree rings reveals details about these past solar outbursts.
Challenges include variable carbon absorption rates and timing across different trees and regions.
SPEs are not predictable but recur over hundreds or thousands of years.
Understanding SPEs is crucial for mitigating future technological and space exploration risks.
Quotes from researchers emphasize the transformative insights offered by tree-ring data.
Research into the 660 BCE event combined data from tree rings and ice cores for accuracy.
The Altai Mountains and Yamal Peninsula are key locations for collecting larch tree samples.
While the Sun’s activity varies, ancient records provide clues about its extreme behavior.

How Trees Record Solar Storms: An Overview

Earth’s ancient trees serve as nature’s archives, preserving invaluable information about past solar storms in their growth rings. These rings capture changes in atmospheric isotopes, offering a unique glimpse into the Sun’s most powerful outbursts.

Solar Particle Events (SPEs)

SPEs are intense bursts of high-energy particles ejected by the Sun during solar flares or coronal mass ejections (CMEs). These particles collide with Earth’s atmosphere, creating cosmogenic isotopes like carbon-14, beryllium-10, and chlorine-36.

What Are Miyake Events?

Named after Japanese physicist Fusa Miyake, these events are periods when solar activity causes a sharp spike in cosmogenic isotopes. The 660 BCE Miyake Event, for example, stands out for its unique double-pulse structure and prolonged impact on atmospheric isotopes.

Tree Rings: Nature’s Timelines

Carbon-14 forms in the atmosphere when cosmic rays collide with nitrogen atoms. It combines with oxygen to form radioactive carbon dioxide, which trees absorb during photosynthesis. This process embeds carbon-14 into their wood as they grow, creating a year-by-year record of atmospheric changes.

Challenges in Interpreting Tree-Ring Data

Variability in Absorption Rates: Different tree species absorb carbon-14 at varying rates.
Lag Time: Carbon-14 takes months to travel from the stratosphere to the lower atmosphere, introducing delays.
Environmental Influences: Factors like growing seasons and regional climate changes affect isotope absorption.

Complementary Ice Core Data

Ice cores from polar regions provide additional isotopic evidence. For instance, beryllium-10 in ice layers can validate findings from tree rings, offering a multi-faceted view of past solar activity.

The 660 BCE Miyake Event: A Case Study

The 660 BCE Miyake Event is one of the most intriguing examples of a solar storm captured in natural archives. Unlike other Miyake Events, it exhibits a double-pulsed structure, with distinct spikes in isotopic levels over a short period.

Key Findings from Research

Dual Peaks: The event featured two significant increases in carbon-14 levels within two years, suggesting consecutive solar outbursts.
Regional Variability: Tree samples from the Altai Mountains and Yamal Peninsula revealed differing absorption patterns, highlighting regional differences in isotope recording.
Magnitude: Carbon-14 production during this period was up to 4.8 times the 11-year solar cycle average.

Table 1: Comparison of Major Miyake Events

Event	Year (Approx.)	Key Characteristics	Implications
774–775 CE	774–775 CE	Sharp single spike in isotopes	Indicated a massive solar storm
660 BCE	664–663 BCE	Double-pulse structure, prolonged impact	Unique evidence of consecutive solar bursts
993–994 CE	993–994 CE	Rapid increase in carbon-14	Confirmed using both tree rings and ice cores

Implications for Modern Technology

Technological Risks

SPEs can severely impact modern technology, including:

Satellites: High-energy particles can damage sensitive electronics and disrupt communication.
Power Grids: Intense geomagnetic storms triggered by SPEs can cause widespread blackouts.
Space Missions: Astronauts face heightened radiation risks during these events.

Frequency of SPEs

Although these events occur every 400–2,400 years, their unpredictability poses significant challenges. The last major SPEs in 774–775 CE and 993–994 CE remind us of the Sun’s potential for destructive power.

Table 2: Isotopes Used to Study SPEs

Isotope	Source	Advantages	Challenges
Carbon-14	Tree rings	Year-by-year precision	Variable absorption by trees
Beryllium-10	Ice cores	Cross-verification of tree-ring data	Less precise due to unclear layer timing
Chlorine-36	Ice cores, sediments	Long-term record of atmospheric changes	Limited availability in natural archives

Facts About Solar Storms

The Aurora Borealis and Aurora Australis are visual effects of solar activity.
The Carrington Event of 1859, the most powerful geomagnetic storm recorded, caused telegraph systems to spark and fail.
SPEs are not only historical; they can happen again, with catastrophic impacts on modern infrastructure.

Future Research Directions

Scientists continue to refine their methods for studying SPEs, including:

Improved Dating Techniques: Advanced models to synchronize tree-ring and ice-core records.
Global Sampling: Expanding isotopic analysis to trees and ice cores from diverse locations.
Predictive Models: Developing forecasts for solar activity to mitigate technological risks.

Earth’s ancient trees and ice cores offer a detailed but complex record of the Sun’s powerful outbursts. Events like the 660 BCE Miyake Event remind us of the Sun’s potential to disrupt life on Earth. While we cannot predict future solar storms, understanding past events equips us with knowledge to prepare for and mitigate their impacts.

Introduction

Albert Einstein’s general relativity is one of the most profound scientific achievements of the 20th century. Its implications extend across the universe, from predicting planetary orbits to understanding black holes. But can this theory withstand the test of time? A monumental new study led by the Dark Energy Spectroscopic Instrument (DESI) indicates that it can.

By examining nearly 6 million galaxies distributed over 11 billion years of cosmic history, researchers have confirmed that the predictions made by Einstein’s equations align remarkably well with observable reality. The results are accessible online through DESI’s published findings on arXiv and related news releases.

Understanding General Relativity

Einstein’s theory describes how gravity arises from the curvature of spacetime caused by mass. Unlike earlier Newtonian concepts, general relativity explains phenomena like:

The bending of light around massive objects (gravitational lensing).

Instead, the booster performed an offshore divert and landed in the Gulf of Mexico, ultimately tipping over and exploding. Despite this, the mission was still considered a success as Starship was placed on a suborbital trajectory, tested key engine capabilities, and made a successful reentry, though with minor damage to its thermal protection system. SpaceX also plans to incorporate improvements in future launches, particularly in the areas of vehicle design and recovery systems.

Summary

Launch Details: SpaceX launched Starship’s sixth test flight from Starbase, Boca Chica, Texas, on November 19.
Launch Window: The liftoff took place at 5:00 PM Eastern, with no reported issues during the countdown.
Booster’s Failure: The Super Heavy booster (Booster 13) was initially intended for recovery at the launch site but was diverted offshore after about three minutes.
Booster’s Final Fate: The booster landed in the Gulf of Mexico and exploded shortly after tipping over.
Starship’s Success: Despite the setback with the booster, the Starship upper stage successfully reached suborbital trajectory.
Reentry Testing: The Starship performed a reentry over the Indian Ocean, with the company purposefully stressing its systems to evaluate the vehicle’s limits.
Flap Damage: Starship sustained minor damage to its flap and thermal protection systems.
Splashdown: The vehicle made a powered soft landing in the ocean and was seen floating on its side in daylight, allowing for better video coverage.
Future Upgrades: SpaceX plans to stretch the Starship for larger propellant tanks and improve its thermal protection systems for future missions.
Flight License: SpaceX was able to conduct this test flight just over a month after the previous one without needing modifications to its Federal Aviation Administration (FAA) license.

Introduction

SpaceX’s Starship program continues to push boundaries with its ambitious goals for space exploration. On November 19, SpaceX launched the sixth test flight of its Starship/Super Heavy vehicle, marking a significant moment in the development of the next-generation spacecraft. However, this launch was not without its challenges. While Starship’s upper stage achieved its mission objectives, the Super Heavy booster was not recovered as planned, ending the mission with a setback. Despite this, SpaceX’s ability to test key systems and collect valuable data for future launches proves that the company is making significant strides in its quest to create a reusable, fully integrated spacecraft for missions to the Moon, Mars, and beyond.

SpaceX’s Starship/Super Heavy vehicle, also known as Starship, took off from SpaceX’s Starbase test site in Boca Chica, Texas. The launch occurred at the opening of a 30-minute window at 5:00 p.m. Eastern, and everything went smoothly during the countdown. Among those in attendance was President-elect Donald Trump, who has maintained a close relationship with SpaceX CEO Elon Musk. The event was a significant milestone for SpaceX, not just because of the launch itself, but also due to the high-profile nature of the occasion.

Following a successful liftoff, the Super Heavy booster, designated Booster 13, separated from the Starship upper stage approximately 2 minutes and 45 seconds after launch. The booster then began its return to the launch site, where SpaceX had planned for it to land. However, just over a minute later, SpaceX engineers announced a “booster offshore divert,” indicating that the booster would not be returning to the launch pad. Instead, the booster made a powered landing in the Gulf of Mexico, just offshore of the launch site. Moments later, the booster tipped over and exploded.

This marked a minor setback for SpaceX, especially following the success of the previous flight on October 13, when the company was able to successfully “catch” the Super Heavy booster back at the launch tower. Despite the booster’s failure to land as planned, the mission was still considered a success due to the Starship upper stage’s ability to complete its objectives.

While the Super Heavy booster failed to land, the Starship upper stage (Ship 31) successfully reached a suborbital trajectory. This achievement was a critical step in SpaceX’s testing program, as it demonstrated that Starship’s propulsion system and overall design were capable of reaching the necessary velocity to enter space. During the flight, SpaceX engineers also performed a test by reigniting one of Starship’s Raptor engines, a critical maneuver for deorbit burns on future missions.

Before the launch, SpaceX had announced that it would be intentionally stressing the limits of the vehicle during the reentry phase. This was done to test the vehicle’s systems and understand how much they could handle in extreme conditions. SpaceX’s Kate Tice, one of the hosts of the webcast, stated, “Do not be surprised if this is not a smooth flight to splashdown today. We are intentionally looking for how far we can push and discover the vehicle’s true limits as we plan for future ship return and catch.”

Starship performed reentry over the Indian Ocean, with the vehicle experiencing some damage to a flap and other parts of the thermal protection system. SpaceX had specifically used an older version of the thermal protection system than the one used in previous flights, another test of the spacecraft’s durability. Despite the damage, Starship survived the reentry and ultimately made a soft landing in the ocean. The successful splashdown took place 65 and a half minutes after liftoff, with the vehicle floating on its side in the daylight hours, allowing for better video coverage of the return.

SpaceX is already planning upgrades to the Starship system for future flights. The company plans to stretch the upper stage of the vehicle to accommodate larger propellant tanks, which will allow for more fuel to be carried on future missions. This will increase Starship’s payload capacity from 1,200 tons to 1,500 tons. Additionally, the design of the vehicle’s forward flaps, used for controlling the vehicle during reentry, will be adjusted. These new flaps will be smaller and placed in a different location to provide better protection against the heat of reentry.

One of the significant upgrades in future flights will involve improving the vehicle’s thermal protection system. SpaceX intends to make modifications to Starship’s heat shields and thermal protection tiles, addressing some of the issues observed during this flight. The company is working toward making the system more robust, ensuring that Starship can handle the extreme heat of reentry during deep-space missions, such as those planned for the Moon and Mars.

FAA Launch License

SpaceX was able to launch this test flight just over a month after the previous one because it did not need to modify its Federal Aviation Administration (FAA) license. The license issued by the FAA for the fifth flight also covered this mission. The limited changes to the vehicle for the sixth test flight were deemed to be within the scope of what had already been analyzed and approved by the FAA.

Facts

SpaceX’s goal is to develop Starship as the most powerful rocket in history, capable of carrying both crewed and uncrewed missions to Mars.
The Super Heavy booster, which is designed to provide the necessary thrust for Starship’s missions, is powered by Raptor engines.
The name “Starship” refers not just to the upper stage of the vehicle but to the entire system, which includes the Super Heavy booster and the upper stage.
SpaceX has been working on the Starship program for several years, with initial tests starting as early as 2019.

Introduction: The Collapse of a Cultural Icon

The recent collapse of the ancient pyramid in Ihuatzio has left both historians and locals in shock. Once one of the most intact structures of the P’urhépecha civilization, this pyramid now lies in ruins after being battered by relentless rainfall. The pyramid, standing at 15 meters tall, was part of a much larger archaeological site that featured multiple pyramids, a fortress, and tombs. This site was of monumental significance to the indigenous P’urhépecha people, who are known for their resistance to the mighty Aztec Empire.

In the wake of the collapse, the local community in Michoacán has expressed profound fear, interpreting the event as a sign of divine displeasure. These reactions highlight the ongoing cultural ties that locals have to their ancestors, who left behind these monumental structures as symbols of their civilization. While Mexico’s National Institute of Anthropology and History (INAH) has pointed to extreme weather conditions as the cause, the public’s perception of the event is shaped by a deep spiritual connection to the land and its history.

The Importance of the Ihuatzio Pyramid

The pyramid in question was part of the Ihuatzio archaeological site, a location with rich historical significance. The site is known for its well-preserved remains of the P’urhépecha civilization, which flourished in the region long before the Aztecs. The P’urhépechas, who occupied the area for centuries, were never conquered by the Aztecs. This historical fact adds an extra layer of significance to the collapse of their pyramid.

The P’urhépechas were skilled in metallurgy, pottery, and architecture, and their monuments, such as the Ihuatzio pyramid, stand as enduring testaments to their culture. The pyramid’s collapse is not only a loss of a physical structure but also a blow to the preservation of P’urhépecha heritage.

The Structural Damage

When the pyramid collapsed, it left a significant portion of the monument in ruins. Specifically, the south wall of the pyramid fell, and six of the pyramid’s stepped bodies were severely damaged, including the retaining walls and core of the structure. The damage is not just structural but also symbolic, as these ancient stones were once part of the civilization’s spiritual and cultural identity.

In addition to the physical damage, the collapse has led to concerns about the future of the site. How can such a historically and culturally significant monument be preserved? The extreme weather that caused the collapse raises important questions about the preservation of ancient sites in a changing climate.

The Role of Weather in the Collapse

According to the National Institute of Anthropology and History (INAH), the collapse was primarily caused by extreme weather conditions, especially the heavy rainfall that struck the area. These weather conditions have been increased by climate change, with many regions experiencing more intense and unpredictable storms. The rain, coupled with the wear and tear from centuries of natural exposure, likely caused the pyramid’s foundation to weaken, resulting in the collapse.

However, locals believe there is more to the story. Many view the event as an omen, a sign from the gods that their spiritual balance has been disrupted. The idea of natural events being tied to divine will is deeply ingrained in the culture of the region. This belief is not uncommon in many indigenous communities, where natural events often hold spiritual significance.

Local Spiritual Interpretations

For the people of Ihuatzio, the collapse of the pyramid is not just a matter of historical or geological interest but a spiritual event. Some residents have openly stated that the collapse represents the displeasure of the gods, a form of divine retribution for actions taken by modern society that have disrupted the natural order.

This spiritual interpretation shows how indigenous beliefs still affect life today. Many people in the region see the collapse as a symbol. It reminds them of their strong bond with the land. It also emphasizes the importance of respecting and preserving their cultural heritage.

Efforts to Restore and Preserve the Site

Despite the collapse, there have been ongoing efforts by INAH and local authorities to restore and protect the Ihuatzio pyramid and the surrounding archaeological site. These efforts are crucial, not just for historical and cultural preservation but also for future generations to learn about the P’urhépecha civilization.

The restoration process is likely to be a long and delicate one. Experts will need to assess the damage, secure the site, and plan for the careful rebuilding of the pyramid’s structural elements. This will likely involve a mix of traditional preservation techniques and modern technology, such as 3D mapping and digital modeling.

Facts:

The P’urhépecha civilization was known for its advanced metallurgy, especially in making copper tools.
Despite the heavy rain, some parts of the pyramid’s structure were so well-built that they withstood the collapse.
The P’urhépecha were one of the few Mesoamerican civilizations that were never conquered by the Aztecs.
Ihuatzio is home to one of the most significant archaeological sites in Michoacán, attracting visitors and researchers alike.
The pyramid is believed to have been constructed around the 14th century.
