For several years now the Kepler Space Telescope, as well as other telescopes, has been discovering an increasing number of exoplanets, with over 2,000 such confirmed worlds found so far (and nearly 5,000 candidates). Today, NASA […]

Kepler Observes Supernova's Shockwave in Visible Light for First Time

An artist's impression of a supernova explosion. With the help of NASA's Kepler space telescope, astronomers were able to observe for the first time the exact moment when the shockwave from a supernova reaches the surface of the progenitor star just before the latter explodes.

The James Webb Space Telescope (JWST) just took a big step toward reality with the successful installation of the first of its many flight mirrors. This is […]

Spitzer Data Suggests Kepler's Strange 'Alien' Star is Surrounded by Comets, not Alien Megastructures

An artist's illustration of cometary fragments passing in front of a star. A new study based on data gathered by NASA's Spitzer Space Telescope suggests that the anomalous dips in brightness that have been observed around the star KIC 8462852 are caused by the fragmentation of similar cometary fragments.

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 Worldwide 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.
