Like the lead character of “Project Hail Mary,” some scientists are proposing ways that life might exist beyond a star’s ...

Europa’s frozen surface is covered with distinctive pairs of ridges that straddle troughs of ice. These double ridges are the most common features on the Jovian moon. But scientists don’t yet have a ...

Understanding liquid states of water at very low temperatures is important for earth sciences and biology but is difficult because supercooled liquid water is very unstable. A new computational study ...

Mars has a history of liquid water on its surface, including lakes like the one that used to occupy Jezero Crater, which have long since dried up. Ancient water that carried debris—and melted water ...

Liquid water is an important prerequisite for life to develop on a planet. As researchers report in a new study, liquid water could also exist for billions of years on planets that are very different ...

Deep beneath the surface of Mars lies a large reservoir of liquid water, according to seismometer data from NASA’s retired InSight lander. The findings, published Aug. 12 in Proceedings of the ...

Data about Mars’ planetary crust gathered from the Mars InSight lander are best explained by the conclusion that the crust has stores of liquid water. Analysis led by Vashan Wright, a geophysicist at ...
