Did life stand a chance on Mars amid extreme climate shifts?
New research suggests that ancient Mars might have experienced alternating hot and cold periods, enabling it to retain liquid water billions of years ago. These fluctuations, however, might have posed challenges for the existence of life due to the varying temperatures and chemical changes in the atmosphere.
