Another 18 exoplanets have been added to the haul, but the difference this time is that all of them are roughly Earth-sized – much smaller than the Neptune-sized average found so far. The discovery was made in old data, using a new and more sensitive algorithm.

After nine years, NASA's exoplanet-hunting Kepler mission came to a final end Thursday as the space agency sent the radio commands ordering the onboard computer to shut down the unmanned space telescope's systems.

Although it’s basically a sure thing that exomoons are out there, astronomers haven’t been able to spot any – until now. Scientists using NASA’s Hubble and Kepler space telescopes have found evidence of a large moon orbiting a gas giant planet some 8,000 light-years away.

NASA’s Kepler Space Telescope has been on shaky ground for some time now. Mission scientists have now placed it into sleep mode in hopes of salvaging what might be its last cache of data, though there are no guarantees.

NASA isn’t done with the Kepler Space Telescope just yet. Its scientists have awoken the deep space probe to gather science data yet again, though with an unknown amount of fuel and a compromised performance, there’s no telling how successful the venture will be.

Watery planets beyond the Solar System may be more common than previously thought, making up 35 percent of exoplanets two to four times the size of the Earth. According to a new study, many planets are made up of half water by mass as opposed to the 0.02 percent water that the Earth has.
