Although NASA's Kepler space telescope ran out of fuel and ended its mission in 2018, citizen scientists have used its data to discover an exoplanet 226 light-years away in the Taurus constellation.The exoplanet, known as K2-288Bb, is about twice the size of Earth and orbits within the habitable zone of its star, meaning liquid water may exist on its surface. It's difficult to tell whether the planet is rocky like Earth or a gas giant like Neptune.The planet is in the K2-288 system, which contains a pair of dim, cool M-type stars that are 5.1 billion miles apart, about six times the distance between Saturn and the sun. The brightest of the two stars is half as massive as our sun, and the other star is one-third of the sun's mass. K2-288Bb orbits the smaller, dimmer star, completing a full orbit every 31.3 days.K2-288Bb is half the size of Neptune or 1.9 times the size of Earth, placing it in the "Fulton gap" between 1.5 and two times the size of Earth. This is a rare size of exoplanet that makes it perfect for studying planetary evolution because so few have been found.The discovery was announced Monday at the 233rd meeting of the American Astronomical Society in Seattle."It's a very exciting discovery due to how it was found, its temperate orbit and because planets of this size seem to be relatively uncommon," said Adina Feinstein, a University of Chicago graduate student in astrophysics and lead author of a paper describing the new planet that was accepted for publication by The Astronomical Journal.Although all of the data from the Kepler mission was run through an algorithm to determine potential planet candidates, visual manpower was needed to actually look at the possible planet transits -- or dip in light when a planet passes in front of its star -- in the light curve data. Kepler observed other events that could be mistaken for planet transits by a computer.But the "reboot" of the Kepler mission in 2014 that led to the K2 mission allowed for multiple observation campaigns that brought in even more data. Every three months, Kepler would stare at a different patch of sky."Reorienting Kepler relative to the Sun caused miniscule changes in the shape of the telescope and the temperature of the electronics, which inevitably affected Kepler's sensitive measurements in the first days of each campaign," said study co-author Geert Barentsen, an astrophysicist at NASA's Ames Research Center, in a statement.Those first three days of data were ignored, and errors were corrected in the rest of the data gathered.But the scientists couldn't do it alone. There were too many light curves to study on their own.So the reprocessed, "cleaned-up" light curves were uploaded through the 2731

A partial government shutdown remains in effect after funding expired for roughly a quarter of the federal government when the clock struck midnight on Saturday — and it is not clear when it will end.Negotiations between congressional Democrats and the Trump administration over the President's demands for a border wall have so far not yielded an agreement, making it likely that the shutdown will continue until after Christmas. It is even possible that it could still be underway when the new Congress starts in early January.Here's a look at the latest on negotiations and the outlook for the partial shutdown:How long is the shutdown expected to last?The President's incoming acting chief of staff Mick Mulvaney 729

A Maryland rapper was shot and killed in Annapolis over the weekend.Officers received a call about shots fired and found a single vehicle crashed at the scene Saturday. The only occupant of that vehicle, Edward Montre Seay, 32, of Chester, died from gunshot wounds, police said.Seay was also a rapper who went by the stage name Tre Da Kid, said Sgt. 362
