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

Amy Klobuchar is ending her Democratic presidential campaign and is set to endorse Joe Biden. Her campaign says she is flying to Dallas and plans to join Biden at his rally Monday night. The Minnesota senator is the third presidential candidate to drop out of the race in less than 48 hours, following Pete Buttigieg’s departure on Sunday and Tom Steyer's exit on Saturday. Their decisions reflect an urgent push among moderates to consolidate behind Biden as a counter to progressive rival Bernie Sanders.Klobuchar outlasted several better-known and better-funded Democrats, thanks to a better-than-expected third-place finish in in New Hampshire. But she couldn't turn that into success elsewhere.Sanders continues to lead all candidates with 60 pledged delegates. Klobuchar picked up seven delegates in the first four states. 840

A police department in Texas has apologized to a man after two mounted police officers leashed him to their horses during an arrest.The photos, taken by bystanders in Galveston, Texas, prompted outrage and accusations of racism against the police department.According to the Galveston Police, 43-year-old Donald Neely was arrested for criminal trespassing on Saturday. During his arrested, two officers — identified only as P. Brosch and A. Smith — clipped a rope to his handcuffs, which was being held by one of the officers.The officers' body cameras were activated at the time. The department did not say whether the two officers had been disciplined. 666
