Today Venus has a dry, oxygen-poor atmosphere. But recent studies have proposed that the early planet may have had liquid water and reflective clouds that could have sustained habitable conditions. Researchers at the University ...
In a first-of-its-kind study, a research team, including Northwestern University's Brian Hoffman and Ajay Sharma, found that ancient bacteria could survive close to the surface on Mars much longer than previously assumed. ...
