Saturn's Moon Mimas May Have an Underground Ocean—or Just a Weird Core

It wasn’t that long ago that Earth was thought to be the only place in the Solar System capable of having liquid water oceans, but now we know of several moons that […]

New Study Points to Alternative Origin for the 'Man in the Moon'

Oceanus Procellarum, or Ocean of Storms, an expansive flat basaltic basin that covers approximately 17 percent of the Moon’s near side, is surrounded by a series of linear gravitational anomalies (shown in red), as revealed by NASA’s GRAIL spacecraft. These anomalies indicate that the large basin was formed by volcanic processes rather than an […]

It's Back! 'Mystery Island' in Titan Sea Makes Unexpected Reappearance

The mystery of an unusual feature in one of Titan’s hydrocarbon seas, dubbed the “mystery island,” has taken an interesting turn. After apparently disappearing following its initial […]

Living On the Edge: The Icy Plains of Enceladus (Part 3)

Lit by reflected light from Saturn, Enceladus appears to hover above the gleaming rings with its well-defined ice particle jets spraying a continuous hail of tiny ice grains, in this image taken by NASA’s Cassini spacecraft in 2006 from a distance of 1.303 million kilometers. The 500-km-wide moon has excited the scientific community and […]

Living On the Edge: Life Under the Ice (Part 1)

After drilling through the 800-meter-thick ice sheet that covers subglacial Lake Whillans in western Antarctica, a U.S. research team discovered a thriving microbial ecosystem on the lake floor that hasn’t been reached by sunlight possibly for up to a million years. The image shows the view down the bore hole as the drill melted […]

Space Dust Indicates Ancient Origin for Saturn's Rings
