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.

We tend to define planets as objects that need a star around which to revolve. Yet, as […]

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.

Peering ever further back in space and time, the Hubble Space Telescope has glimpsed the largest known group of the faintest and youngest primordial galaxies ever—over 250—some of which are estimated […]

Astronomers Begin Woldwide Observations of 'Unusual' Star as SETI Listens for Alien Signals

Astronomers have begun a close-up study of the unusual star KIC 8462852 in the hopes of explaining Kepler's enigmatic observations. To that end, the American Association of Variable Star Observers recently issued a call to the astronomical community worldwide for more detailed observations, while the SETI Institute has began searching for possible radio signals of artificial origin in KIC 8462852's vicinity.

Planetary debris disks, or protoplanetary disks, are some of the most interesting phenomena in astronomy – these giant clouds of dust and gas surrounding young stars are the birthplaces of new planets. Now, astronomers […]

Planets Around Red Dwarf Stars Could Be More Life-Friendly Than Previously Thought, According to New Study
