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 […]

When the topic of ice on Mars comes up, the first thing that usually comes to mind are the polar ice caps which are prominent even in small […]

NASA Mars Orbiter Examines Dramatic New Crater

A dramatic, fresh impact crater dominates this image taken by the High Resolution Imaging Science Experiment (HiRISE) camera on NASA’s Mars Reconnaissance Orbiter on Nov. 19, 2013.

Space rocks hitting Mars excavate fresh craters at a pace of more than 200 per year, but few new Mars scars pack as much visual punch as […]

Will Curiosity Find New Clues to Ancient Martian Habitability, or Perhaps Even Life, at Hematite Ridge?

As the Curiosity rover gets ever closer to its major destination of Mount Sharp, there is an interesting feature there which has become a priority target, one which may help scientists to further […]

Comet ISON Appears In Tact As it Plunges Toward Perihelion Next Month

NASA’s Hubble Space Telescope captured this image of Comet ISON on Oct. 9, 2013. The image suggests that the comet is intact, a good sign that it will survive perihelion next month when it dives to within one million miles of the Sun’s surface.
