Muddy Mars: New Evidence for Liquid Water Flows Within Past Million Years

Illustration of debris flows inside Istok crater on Mars, which have provided evidence of large amounts of flowing water and mud in the past. The flows are very similar to ones on Earth in Arctic regions such as Iceland. Image Credit: Nature Communications

The fact that Mars used to have large amounts of liquid […]

The exploration of the outer Solar System has revealed a plethora of amazing worlds, the likes of which […]

Researchers Develop New Technique to Search for Chemical Evidence of Life on Mars

Despite decades of searching, definitive evidence for life on Mars, past or present, has still remained elusive and controversial. Confirmation of such a finding would need to be thoroughly tested and documented, and now researchers at the University of Kansas have developed a new technique that they hope would help to do just that, […]

Dark Material in Fractures on Europa's Surface Is Sea Salt, New Research Suggests
