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 […]

A Moon Falling Apart: Grooves on Phobos Are a Sign of its Eventual Catastrophic Fate

The unusual grooves on Phobos' surface, such as those on the left side of this image, are now thought to be caused by tidal stress. The large crater Stickney is in the upper portion of the image. Image Credit: NASA/JPL-Caltech/University of Arizona

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

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.
