A Martian Autumn Begins
Just like Earth, Mars experiences seasons because its axis is tilted. This Hubble Space Telescope image captured the beginning of autumn in Mars's northern hemisphere. The image allowed astronomers to observe changes in the planet's atmosphere. Understanding Martian seasons helps us interpret weather patterns and climate history on the red planet.
