New evidence for ancient ocean on Mars

Did a vast ocean once cover Mars' northern plains? The idea has been hotly debated among scientists for the past 20 years, ever since Viking Orbiter images revealed possible ancient shorelines near the pole. Later findings ...

Changes in Titan's surface brightness point to cryovolcanism

Changes in surface brightness on Titan observed over four years by NASA's Cassini spacecraft have added to evidence that cryovolcanism is active on Saturn's largest Moon. Anezina Solomonidou has presented results at the European ...
