Life on the Moons of Jupiter and Saturn through Panspermia?

  A new study suggests the possibility of transfer of life from the inner Solar System to the moons orbiting Jupiter and Saturn, although very rare, cannot be ruled out. A comparison portrait of Jupiter’s four Galilean moons Io, Europa, Ganymede, and Callisto, each with different characteristics. (In this image composite, Jupiter is not at [continue reading]

Best Spots on Europa to Search for Extraterrestrial Life

  The surface of Jupiter’s moon Europa exposes material churned up from inside the moon and also material resulting from matter and energy coming from above. If you want to learn about the deep saltwater ocean beneath this unusual world’s icy shell — as many people do who are interested in possible extraterrestrial life — [continue reading]

Anne's Picture of the Day: Jupiter’s moon Europa

March 19, 2013 Jupiter’s icy moon Europa Image Credit: NASA/JPL/DLR Jupiter’s moon Europa is, with just over 3,100 kilometers (1,900 mi) in diameter, slightly smaller than Earth’s Moon. It is the sixth-largest moon of Jupiter, and the smallest of its four Galilean satellites but nonetheless more massive than all known moons in the Solar System [continue reading]

Water from Europa's Ocean Sometimes Comes to the Surface

  With data collected from the mighty W. M. Keck Observatory, California Institute of Technology (Caltech) astronomer Mike Brown — known as the Pluto killer for discovering a Kuiper-belt object that led to the demotion of Pluto from planetary status — and Kevin Hand from the Jet Propulsion Laboratory (JPL) have found the strongest evidence [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]

Arctic Bacteria Help in the Search for Life on moon Europa

  In a fjord in Canada scientists have found a landscape similar to one of Jupiter’s icy moons: Europa. It consists of a frozen and sulfurous environment, where sulfur associated with Arctic bacteria offer clues for the upcoming missions in the search for traces of life on Europa. Artist’s concept of Jupiter’s icy moon Europa. Credit: NASA/JPL-Caltech [continue reading]
