Thousands of exoplanets have been discovered so far – just over 4,000 now actually – with thousands more expected to be found in the near future. But these worlds are very far away, so […]

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 […]

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

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

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 […]

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 […]

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 […]

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 […]

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.
