First there were the unusual bright spots on Ceres, which are still awaiting an explanation, and now as New […]

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 […]

Saturn’s largest moon, Titan, has seas and lakes of liquid methane and ethane dotting its surface, but one question scientists have been trying to figure out is how the hollows in the ground, which hold the lakes, form to begin with. Now, a […]

The debate over whether Mars used to be warmer and wetter or colder and wetter earlier in its history has been a long and contentious one. Now, a new study suggests it may be the latter, that […]

Saturn's Massive Phoebe Ring Even Larger Than Previously Thought

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, […]

With so much attention now on the rovers and spacecraft at Mars, Saturn, Ceres, comet 67P/Churyumov-Gerasimenko, and, soon, Pluto, it may seem like Earth’s closest planetary neighbor Venus has been forgotten again. But no, […]
