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 […]

By Leonidas Papadopoulos, on July 6th, 2015 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 […]

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 […]

By Emily Carney, on March 14th, 2015 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 […]

By Leonidas Papadopoulos, on December 24th, 2014 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 […]

By Leonidas Papadopoulos, on September 5th, 2014 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.
