Exoplanets – planets orbiting other stars – have been found by the thousands now, with many more to come. But what about exomoons? So far there haven’t been any confirmed yet, and they are much more difficult to detect, […]

Kepler Enters Hibernation Mode, Downlinks Latest Science Data Before Fuel Runs Out

Artist’s conception of the Kepler Space Telescope in space. Fuel is now running very low and the spacecraft has downlinked its latest science data to Earth. Image Credit: NASA/AP

The end is nigh – that appears to be the case at least for NASA’s Kepler Space Telescope which is now running very low on […]

The discovery of thousands of exoplanets in recent years is one of the most exciting developments in space exploration, and the future promises the detection of thousands more. Many of those have come from the Kepler Space Telescope, including Earth-sized planets in the habitable […]

Moons are exceedingly common in the Solar System – Jupiter alone has 67! But smaller planets do as well of course, except for Mercury and Venus, and even some […]

Pale Red Dot: Astronomers Discover Potentially Habitable Exoplanet Orbiting Nearest Star

Artist’s conception of what Proxima b might look like. It is just slightly more massive than Earth and orbits in its star’s habitable zone. Temperatures might allow liquid water to exist on its surface. A potentially habitable world, it is also now the closest known exoplanet. Image Credit: ESO/M. Kornmesser

Astronomers today announced one […]

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.

One of the most impressive […]

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.

What is […]

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

Astronomers have begun a follow-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 […]

Kepler Observes White Dwarf Star Disintegrating Its Planet(s)

An artist’s concept of a minor planet being disintegrated by a white dwarf star. New observations by NASA’s Kepler space telescope have indicated that this indeed takes place around WD 1145+017, a white dwarf located 570 light-years away. Image Credit: CfA/Mark A. Garlick

One of the wonderful things of living in a galaxy populated […]

The Kepler Discovery Controversy: Objects Orbiting New Star Likely Cometary Fragments, Not Aliens

Are the unusual objects around KIC 8462852 a giant swarm of comets or something else? Image Credit: NASA/JPL-Caltech/T. Pyle (SSC)

There has been a lot of discussion during the past several days regarding a discovery by the Kepler Space Telescope, which, according to some, might be the first evidence for advanced extraterrestrial intelligence, or […]
