- To date, no conclusive evidence of past or present life has been found on Mars. Cumulative evidence suggests that during the ancient Noachian time period, the surface environment of Mars had liquid water and may have been habitable for microorganisms, but habitable conditions do not necessarily indicate life.

2 days ago · Like Earth, Mars was formed about 4.5 billion years ago, but its early surface was very different than today's. Mars' surface then had high rates of meteorite and asteroid impacts from the period ...
2 days ago · The northern and southern hemispheres of Mars look very different. About one-third of the surface of Mars – mostly in its northern hemisphere – is 2 to 4 miles (3.2-6.4 kilometers) lower in ...
2 days ago · Conceivably, if life exists (or existed) on Mars, evidence of life could be found, or is best preserved, in the subsurface, away from present-day harsh surface conditions. [55] Present-day life on Mars, or its biosignatures, could occur kilometers below the surface, or in subsurface geothermal hot spots, or it could occur a few meters below the surface.
3 days ago · This freeze-thaw cycle gives rise to a variety of curious surface features, many of which are captured in these images of the Australe Scopuli region close to the south pole of Mars. The images were taken by the High Resolution Stereo Camera (HRSC) onboard Mars Express on 2 April 2024 during southern hemisphere spring.
2 days ago · The icy moon Europa was picked out by NASA as one of the most likely places to support life, due to an ocean of liquid water which scientists believe might lurk beneath the surface. NASA official Gina DiBraccio described it as “one of the most promising places to look for life beyond Earth.”. The Europa Clipper mission will look for ...
5 days ago · Although the surface of Mars is frigid and hostile to life today, NASA's robotic explorers at Mars are searching for clues as to whether it could have supported life in the distant past. Researchers used instruments on board Curiosity to measure the isotopic composition of carbon-rich minerals (carbonates) found in Gale crater and discovered new insights into how the Red Planet's ancient ...
4 days ago · This is the latest in a long history of studies trying to piece together the past climate of Mars. Others have suggested the red planet once had an ocean. Whatever the case, Mars reached a tipping ...
