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 […]

With so many exoplanets now being discovered on a regular basis by astronomers, the focus has turned to what number of them might be habitable for some kind of life. For life as we know it at least, that depends on a number of […]

NASA’s next spacecraft destined for Mars, MAVEN, is in its final month of pre-launch processing at Kennedy Space Center in Florida. After a decade of work from people across the country, and having passed some 270 reviews, MAVEN […]

Is Climate Change Cyclical? NASA Study Suggests Yes

The severity of the current Climate Change “crisis” has been blamed almost exclusively on man-made carbon-dioxide emissions and that the change is permanent. A recent study conducted by several universities as well as NASA point to an “inconvenient truth” – that neither of these statements is true.
