Astronomers Identify New Substances on Europa of Possible Underground Origin

An image mosaic of Europa taken from NASA’s Galileo spacecraft, showing the moon’s famous “chaos terrain” of linear cracks and ridges that crisscross almost its entire surface. A new research by a team of U.S. astronomers has identified a previously unseen set of minerals along Europa’s chaos terrain, which are thought to have originated […]

The Science of Pluto: The Sails of Charon (Part 2)

An artist’s concept of Charon (at front), with Pluto seen in the background. Equally as fascinating and exciting as Pluto, Charon has sported its own set of intriguing mysteries and unanswered questions, some of which include the exciting possibility for the existence of geyser-like surface eruptions, underground layers of liquid water, and even the […]

New Study Suggests Pluto's Charon May Have Harbored Underground Oceans Long Ago

An artist’s depiction of Pluto, as seen from the surface of its largest moon Charon. A recent study by a team of US astronomers argues that Charon might harbor frozen underground oceans of liquid water, the pressence of which could be inferred by surface geologic features that could be visible to the New Horizons […]

Hubble Shows Evidence of Large Underground Ocean on Ganymede

From HubbleSite: “NASA’s Hubble Space Telescope observed a pair of auroral belts encircling the Jovian moon Ganymede. The belts were observed in ultraviolet light by the Space Telescope Imaging Spectrograph and are colored blue in this illustration. They are overlaid on a visible-light image of Ganymede taken by NASA’s Galileo orbiter. The locations of […]

New Study Suggests Europa Is Far Less Geophysically Active Than Previously Thought

An artist’s impression of Jupiter and its moon Europa, based on actual visible light images. Last year, a team of astronomers using the Hubble Space Telescope, had reported the detection of signs of water vapour being vented off Europa’s south pole. A new study comes to challenge this interpretation, by presenting evidence that Europa’s […]

Living On the Edge: The Mysterious Lakes of Titan (Part 4)

Titan’s colorful globe passes in front of Saturn and its rings, in this true color image taken in 2011 from NASA’s Cassini spacecraft. The moon’s opaque atmosphere hides a fascinating surface that is rich in methane lakes, water ice, and organic compounds. Image Credit: NASA/JPL-Caltech/Space Science Institute

Living On the Edge: The Inviting Waters of Europa (Part 2)

Jupiter’s moon Europa, as seen by NASA’s Galileo spacecraft. A long line of evidence has shown that Europa has an underground ocean of liquid water, which for many scientists constitutes the best place in the Solar System to search for alien life. Image Credit: NASA/JPL/Ted Stryk

“Since ’tis certain that Earth and Jupiter have […]
