Trying to understand the ancient climate of our own planet is hard enough, but to understand Mars' climatic history, planetary scientists have had to turn to a rather inventive method of climate forensics. Continue reading →
NASA's Saturn-orbiting Cassini spacecraft has imaged something peculiar on the outermost edge of the gas giant's A-ring. Continue reading →
New modeling of the Pluto-Charon system give good reasons to suspect that the surface of Pluto will be riddled with faults caused in part from a liquid ocean that once lie hidden under the icy surface.
On April 21 -- if not sooner -- the Lunar Atmosphere and Dust Environment Explorer will crash into the surface of the moon and vaporize. But before that happens, NASA has a low-fly mission planned.
Scientists have announced the discovery of a sub-surface ocean on the Saturnian moon Enceladus -- explore the tiny world's icy surface and water ice geysers in this stunning collection of images from NASA's Cassini mission.
On April 8, Mars will be at opposition in the night sky -- here's how you can get the best astronomical viewing opportunities.
Gravity measurements indicate the small moon Enceladus has an ocean sandwiched between its rocky core and icy shell, a finding that raises the prospects of a niche for life beyond Earth.
It can be stressful being a small asteroid -- not only do they risk collision with the planets any time, they are also slowly being eroded by the sun. Continue reading →
