A view of the Halley 6 Research Station situated on the Brunt Ice Shelf, Antarctica, which is believed to be the closest thing you can get to living in space without leaving Earth, making it perfect to be used for research by the European Space Agency.

Meteorites delivered water ice to asteroids in early solar system

28 June 2016 Astronomy Now

Planetary scientists have discovered pieces of opal in a meteorite found in Antarctica, a result that demonstrates that meteorites delivered water ice to asteroids early in the history of the solar system. Opal, familiar on Earth as a precious stone used in jewellery, is made up of silica (the major component of sand) with up to 30 percent water in its structure.

Computer model explains sustained eruptions on Saturn’s moon Enceladus

29 March 2016 Astronomy Now

NASA’s Cassini spacecraft has observed geysers erupting on Saturn’s icy moon Enceladus since 2005, but the process that drives and sustains these eruptions has remained a mystery. Now, scientists have pinpointed a mechanism by which cyclical tidal stresses exerted by Saturn can drive Enceladus’s long-lived eruptions.
