Large Ocean Inside Saturn's Moon Enceladus

  NASA’s Cassini spacecraft and Deep Space Network have uncovered evidence Saturn’s moon Enceladus harbors a large underground ocean of liquid water, furthering scientific interest in the moon as a potential home to extraterrestrial microbes. Gravity measurements by NASA’s Cassini spacecraft and Deep Space Network suggest that Saturn’s moon Enceladus, which has jets of water vapor [continue reading]

Explosive Crater Twins on Mars

  Dramatic underground explosions, perhaps involving ice, are responsible for the pits inside two large martian impact craters, here imaged by ESA’s Mars Express on 4 January. High-Resolution Stereo Camera nadir and color channel data taken during orbit 11467 on 4 January 2013 by ESA’s Mars Express have been combined to produce this color view of two craters, both [continue reading]

Reull Vallis: a Former River on Mars?

  ESA’s Mars Express imaged the striking upper part of the Reull Vallis region of Mars with its high-resolution stereo camera last year. High-Resolution Stereo Camera (HRSC) nadir and colour channel data taken during revolution 10657 on 14 May 2012 by ESA’s Mars Express have been combined to form a natural-colour view of Reull Vallis. Centered at [continue reading]

Snow And Ice on Oven-Hot Venus?!

  Venus Express has spied a surprisingly cold region high in the planet’s atmosphere that may be frigid enough for carbon dioxide to freeze out as ice or snow. This image of the Venus southern hemisphere illustrates the terminator – the transitional region between the dayside (left) and nightside of the planet (right). The south [continue reading]

Does Jupiter's Moon Europa Have a Subsurface Ocean?

  Europa, the enigmatic moon of Jupiter, is believed to be home to a subsurface ocean of liquid water. However, future missions to explore Europa’s ocean may need to dig deep. Research suggests that water does not stay in a liquid state near Europa’s surface for longer than a few tens of thousands of years [continue reading]
