ExoMars Observes Water Frost On The Caldera Floor of the Ceraunius Tholus Volcano

by Keith Cowing

Researchers have discovered frost atop volcanoes near Mars’s equator for the first time – a part of the planet where it was thought impossible for frost to form. The finding […]

Hydrothermal Vents On The Seafloors Of Ocean Worlds Could Support Life

by Keith Cowing

We’ve all seen the surreal footage in nature documentaries showing hydrothermal vents on the frigid ocean floor—bellowing black plumes of super-hot water—and the life forms that cling to them. Now, […]
