Woods Hole Oceanographic Institution Selected By NASA To Investigate Ocean Worlds And Their Organic Carbon Cycles

by Keith Cowing

Ocean worlds such as Jupiter’s icy moon Europa and Saturn’s counterpart, Enceladus, could be among the most favorable places to discover life beyond Earth—and perhaps even a second, independent origin […]

Icy Worlds: Moons And Dwarf Planets

by Keith Cowing

In the outer solar system beyond Jupiter, water ice is a dominant component of planetary bodies, and most solid objects in this region are classified as icy bodies.

Cassini Study Found Organics From An Ocean Inside Enceladus

by Keith Cowing

NASA’s Cassini spacecraft captured dramatic plumes, both large and small, spray water ice out from many locations along the famed ‘tiger stripes’ near the south pole of Saturn’s moon Enceladus.

Geochemical Mobility of Elements in Antarctic Environments Affected by CO2-Rich Hydrothermal Fluids: Astrobiological Implications

by Keith Cowing

Hydrothermal systems are widespread in our solar system. Identification of alteration mineral assemblages on Mars and potentially in ocean worlds such as Enceladus suggests the existence of extensive hydrothermal fluid-igneous […]
