Just in time for Halloween, astronomers have announced the discovery of huge stars that spin so fast they start to resemble awesome stellar pumpkins. And these “pumpkin stars” are incredible X-ray generators, producing radiation hundreds of times more powerful than our sun. Continue reading ‘Pumpkin Stars’ Are All You Need for a Stellar Halloween
A new analysis of data collected during the Kepler space telescope’s prime planet-hunting mission shows that 1,284 candidate planets are indeed confirmed exoplanets, boosting the current tally of worlds beyond the solar system to 3,264. Continue reading Kepler Space Telescope Confirms 1,284 New Planets
After a weekend of uncertainty for the Kepler spacecraft, NASA let out a sigh of relief on Monday, saying that “the spacecraft reached a stable state with the communication antenna pointed toward Earth.”
NASA posted a statement from mission manager Charlie Sobeck on Monday, saying that the “mission has cancelled the spacecraft emergency, returning the Deep Space Network ground communications to normal scheduling.” Continue reading Kepler Spacecraft Stabilized After Unexplained Emergency
