NASA Reveals Stunning Ultraviolet Photos of Mars, Capturing Changing Seasons
SPACE — In a surprising twist, NASA has shared photographs of the planet Mars in a different color than its iconic red hue. The images, taken in July 2022 and January 2023, showcase the changing seasons on the red planet.
The photographs were captured by astronomers using the Mars Atmosphere and Volatile EvolutioN (MAVEN) spacecraft, owned by the American Space Agency. The MAVEN Imaging Ultraviolet Spectrograph (IUVS) instrument measured wavelengths outside the visible spectrum, between 110 and 340 nanometers.
The first photo, taken in July 2022, reveals a purple area representing ozone in the Martian atmosphere. The white and blue areas indicate clouds or fog in the planet’s sky, while the surface of Mars appears brown or green in the ultraviolet light. By viewing the planet in these wavelengths, scientists gain unique insights into the Martian atmosphere and surface features.
The second image, captured in January 2023, showcases the northern hemisphere of Mars after it has passed the farthest point in its orbit around the sun. This results in an abundance of white clouds in the north polar region. Ozone accumulation can also be seen at the top of the planet, formed during the cold polar nights of the northern winter.
These photographs highlight the rapidly changing seasons on Mars. Similar to Earth, Mars experiences four distinct seasons due to its oblique axis of rotation. However, the Martian seasons are approximately twice as long as those on Earth, as Mars has a longer year.
During the southern summer, when Mars is closest to the sun, temperatures rise significantly, leading to more turbulence, stronger winds, and larger dust storms in the southern hemisphere. The first image captured one of Mars’ deepest craters, the Argyre Basin, filled with atmospheric fog. The deep canyon of Valles Marineris appears to be filled with clouds.
In contrast, the northern hemisphere experiences its summer when Mars is farther away from the sun. This results in cooler temperatures and an abundance of white clouds in the north polar region, as seen in the second image.
The changing seasons also impact the polar ice caps on Mars. Warmer summer temperatures cause the south polar ice cap to shrink, releasing carbon dioxide and thickening the atmosphere. However, the increase in water vapor during spring destroys the ozone layer in the Northern Hemisphere.
The MAVEN spacecraft, launched in November 2013, aims to study Mars’ atmospheric gases and understand the planet’s evolution over time. By studying atmospheric loss, scientists gain insights into Mars’ history, including its atmosphere, climate, liquid water, and potential habitability.

SPACE — Mars, often referred to as the red planet, has captivated astronomers once again with a series of breathtaking photographs showcasing its appearance in a different color. The images, shared by NASA on June 22, were taken when Mars was near the opposite end of its orbit around the sun.
Using the Mars Atmosphere and Volatile EvolutioN (MAVEN) spacecraft, astronomers were able to capture the unique beauty of Mars in ultraviolet light. The first photo, taken in July 2022, shows the planet during its summer season in the southern hemisphere when it is closest to the sun.
The photo reveals a purple area representing ozone in the Martian atmosphere, while white and blue areas indicate clouds or fog in the planet’s sky. The surface of Mars appears brown or green in these new images. NASA officials stated that viewing the planet in ultraviolet wavelengths provides scientists with extraordinary insights into the Martian atmosphere and surface features.
These photographs also highlight the rapidly changing seasons on Mars. Similar to Earth, Mars experiences four distinct seasons due to its oblique axis of rotation. However, the Martian seasons are approximately twice as long as those on Earth, as Mars has a longer year.
During the southern summer, when Mars is closest to the sun, temperatures rise significantly, leading to more turbulence, stronger winds, and larger dust storms in the southern hemisphere. The first image captured in July 2022 showcases one of Mars’ deepest craters, the Argyre Basin, filled with atmospheric fog. Additionally, the deep canyon of Valles Marineris appears to be filled with clouds.
As Mars orbits farther from the sun, the northern hemisphere tilts towards it, resulting in a colder northern summer. The second image, taken in January 2023, displays an abundance of white clouds in the north polar region. Ozone accumulation can also be observed at the top of the planet, formed during the cold polar nights of the northern winter. However, the increase in water vapor during spring will destroy the ozone layer in the Northern Hemisphere.
The MAVEN spacecraft, launched in November 2013, has been instrumental in studying Mars’ atmospheric gases. It has also detected increased hydrogen loss from Mars, likely caused by dust storms pushing water vapor to great heights. By studying these atmospheric changes, scientists hope to gain a better understanding of Mars’ evolution over time and its potential habitability.
The stunning photos of Mars in ultraviolet light serve as a reminder of the planet’s unique beauty and the ongoing exploration efforts to unravel its mysteries. As NASA continues to delve deeper into the secrets of the red planet, humanity’s understanding of our neighboring world continues to expand.
What insights can be gained from studying Mars’ atmospheric gases and atmospheric loss, as observed by the MAVEN spacecraft, regarding the planet’s history and potential habitability
Nary insights into the Martian atmosphere and surface features.
The second image, captured in January 2023, showcases the northern hemisphere of Mars after it has passed the farthest point in its orbit around the sun. During this time, Mars experiences its summer in the northern hemisphere. The image displays an abundance of white clouds in the north polar region and ozone accumulation at the top of the planet, formed during the cold polar nights of the northern winter.
These photographs illustrate the changing seasons on Mars, which are influenced by its oblique axis of rotation. Similar to Earth, Mars experiences four distinct seasons, but they are approximately twice as long due to its longer year. During the southern summer, Mars experiences higher temperatures, leading to more turbulence, stronger winds, and larger dust storms in the southern hemisphere. The first image captured the Argyre Basin, one of Mars’ deepest craters, filled with atmospheric fog. The second image displays cooler temperatures and an abundance of white clouds in the north polar region during the northern hemisphere’s summer.
The changing seasons also have an impact on Mars’ polar ice caps. Warmer summer temperatures cause the south polar ice cap to shrink, releasing carbon dioxide and thickening the atmosphere. However, the increase in water vapor during spring leads to the destruction of the ozone layer in the Northern Hemisphere.
