Heating ocean moon Enceladus for billions of years



Paris (ESA) Nov 08, 2017
Enough heat to power hydrothermal activity inside Saturn's ocean moon Enceladus for billions of years could be generated through tidal friction if the moon has a highly porous core, a new study finds, working in favour of the moon as a potentially habitable world. A paper published in Nature Astronomy presents the first concept that explains the key characteristics of 500 km-diameter Enceladus as observed by the international Cassini spacecraft over the course of its mission, which concluded in Se ... read more

To keep Saturn's A ring contained, its moons stand united
Ithaca NY (SPX) Oct 25, 2017
For three decades, astronomers thought that only Saturn's moon Janus confined the planet's A ring - the largest and farthest of the visible rings. But after poring over NASA's Cassini mission data, ... more

Saturn's A ring contained by not one, but seven moons
(UPI) Oct 17, 2017
Until recently, astronomers assumed Saturn's A ring was contained by a single moon, Janus, the gas giant's largest. But new research shows the A ring, the outermost of Saturn's large, bright rings, is confined by seven moons. ... more

A team of mainly Dutch astronomers has observed moving shadows on a dust disk around a star. On multiple days they took a 'photo' of the star and its disk. They used the SPHERE instrument, partially built in the Netherlands, on the Very Large Telescope in Chile. Probably, processes in the inner disk cast their shadows at the outer disk. The astronomers publish their findings in The Astrophysical ... more
