How Enceladus got its stripes

Saturn's icy moon Enceladus is of great interest to scientists due to its subsurface ocean, making it a prime target for those searching for life elsewhere. New research led by Carnegie's Doug Hemingway reveals the physics ...

Warming ocean layers will undermine polar ice sheets

Warming of the ocean's subsurface layers will melt underwater portions of the Greenland and Antarctic ice sheets faster than previously thought, according to new University of Arizona-led research. Such melting would increase ...

Triton: A subsurface ocean?

Neptune's largest moon Triton is most likely a captured Kuiper Belt Object. The capture of icy Triton and the subsequent taming of its orbit likely led to the formation of a subsurface ocean through tidal heating. New research ...

Gas insulation could be protecting an ocean inside Pluto

A gassy insulating layer beneath the icy surfaces of distant celestial objects could mean there are more oceans in the universe than previously thought. Computer simulations provide compelling evidence that an insulating ...

Cassini finds hints of activity at Saturn moon Dione

(Phys.org) —From a distance, most of the Saturnian moon Dione resembles a bland cueball. Thanks to close-up images of a 500-mile-long (800-kilometer-long) mountain on the moon from NASA's Cassini spacecraft, scientists ...

Breaking Antarctica's ice

Over the course of the past decade, NASA spacecraft have identified several sites on Mars where conditions capable of supporting life existed in the past. One of the most promising of these sites, and a good candidate for ...

Flash floods in Mangala Valles via Mars Express orbiter

Catastrophic flooding triggered by ice melting from the heat of volcanic activity is thought to be responsible for the chaotic scenery depicted in this region of the Mangala Valles channel network.

SWIM project maps potential sources of Mars water

Missions carrying humans to Mars will require on-site resources, and a project led by Planetary Science Institute (PSI) scientists Nathaniel Putzig and Gareth Morgan is mapping the availability of potential shallow water-ice ...
