Hints of buried water on Mars have swung between tantalizing and controversial, but one idea keeps resurfacing: lakes could persist if they sit beneath a protective lid of ice. Instead of needing a ...

If life ever existed on Mars, traces of it might still be frozen beneath the planet's icy surface. A new study from NASA and Penn State University suggests fragments of biomolecules from ancient ...

Mars has long been painted as a dead world of dust and radiation, a place where human visitors would survive only inside ...

Small lakes on ancient Mars may have remained liquid for decades, even with average air temperatures well below freezing. Using a climate model adapted for Martian conditions, a team of researchers ...

The lumps frozen in Mars' mantle may have been there for billions of years. Astronomers may have figured out where the mysterious blobs embedded in Mars' mantle originated. The mysterious lumps have ...

The findings potentially solve the paradox of how liquid water seems to have persisted on Mars even when the climate grew too cold. When you purchase through links on our site, we may earn an ...

Changes in Mars’ axial tilt (obliquity) drive shifts between polar ice caps at low obliquity and widespread mid-latitude glaciation at high obliquity. These cycles result in ice accumulating inside ...

The UA Lunar and Planetary Lab has released a particularly beautiful new batch of HiRISE photos of the Martian surface this week. See them here. Don’t forget: The LPL is having a picnic on Mount ...
