As has been reported previously on AmericaSpace, and elsewhere, there is something weird going on around a star which is a little over 1,400 light-years away. Astronomers are still baffled as to […]

New 2016 NASA Budget Fully Funds Europa Mission, Including Lander

A view many have been waiting for - artist's concept of the surface of Europa. The new NASA budget brings this closer to reality, with funding for not only a flyby probe, but also a lander. Image Credit: NASA/JPL-Caltech

Astronomers have discovered another Earth-sized exoplanet that¬†is the closest one to our own Solar System found so far, but it might not be a nice place […]

SETI Detects No Alien Signals Coming from Strange Star, Continues Searching

The SETI Institute has recently undergone a search for alien radio signals around the star KIC 8462852, whose mysterious brightness fluctuations have been considered to be the workings of an extraterrestrial civilisation. Following a thoroiugh search in a wide range of frequencies, SETI reported that it has detected no such signals that could be of artificial origin. Image Credit: Graeme L.

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 US astronomers has identified a previously unseen set of minerals along Europa's chaos terrain, which are thought to have originated from the moon's underground liquid water ocean.
