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 shooting at a bowling alley late Friday left three men dead and four people wounded in Southern California, and police are trying to find whoever fired the shots, authorities said.The gunshots at the Gable House Bowl in Torrance went off just before midnight. A fight -- first involving young ladies, then men -- happened shortly beforehand, sending people running, a witness said."Then ... maybe a minute and a half later, all of the sudden all we heard was, pop, pop, pop," the witness, Dana Scott, told RMG News. "Bowlers were diving under the benches. The people that were still bowling on the lanes were on the floors, underneath the seats.""People were looking for their parents, because this is a family league. You've got mothers, fathers, sons, daughters ... everybody's friends in that league," she said.No arrests were immediately reported after the shooting. City police were "working to identify the suspect(s) involved," they said in a news release.By late Saturday morning, relatives of those who were shot were clustered outside the bowling alley, standing behind yellow police tape. Some of them embraced one another; others looked toward the building's rear, where a coroner's van pulled out.Keithnisha More, one of those standing outside Saturday, said her brother-in-law was one of those who died and that he leaves behind a son."How do you explain to a 5-year-old boy that his father is dead?" More said. "How does my sister-in-law tell this little boy that daddy is gone? Just gone."The names of the dead and wounded weren't immediately released.Witness: 'People started to run'A man who says he was in a karaoke area of the building when the shooting happened described a scene of panic."People started to run inside the karaoke (area), shouting, 'Gunshot, gunshot, gunshot,'" the man, identified on Facebook as D Ryon Thomas, says in a video posted to the social network.Staff ushered people into an area in the back of the building, he said.Police ask public for videoDetectives are going to examine surveillance video recorded inside the building, Torrance police Sgt. Ron Harris said."We're also asking anyone in the public who might have seen anything, or (recorded) any cell phone video or other video, to come forward and help in this investigation," Harris said.Torrance police officers saw multiple people with gunshot wounds when they arrived, and they started lifesaving measures, including CPR and using a defibrillator, police said in a news release.Video from RMG News showed numerous firefighters or other first responders tending to people outside.The Gable House Bowl is open until 3 a.m. on Saturdays. The complex also offers laser tag and a bar, its website says.Torrance is about 20 miles from Los Angeles. 2763

A Texas police officer shot his adult son Saturday, thinking he was an intruder.Dispatchers received a call around 6 p.m. CDT from a man reporting a shooting at his home. The man said he was an off-duty Dallas officer who mistook his son for an intruder and accidentally shot him, according to a release from the DeSoto Police Department. DeSoto is a city south of Dallas.When officers arrived on scene, they found the victim bleeding from his right forearm. The victim was taken to a hospital with non-life-threatening injuries, the release said."It was a startling situation, it was an accident," Pete Schulte, DeSoto police spokesman, told 655

After having trouble conceiving on their own, a white couple opted for in-vitro fertilization and gave birth to a baby girl. When their daughter was a toddler, they grew concerned that she didn't look like them."When she was born, all my friends said, 'Oh, she looks Asian, she looks Asian,'" said Kristina Koedderich, the girl's mother. "We were cracking the jokes... but you just figure every baby, like, looks different when they're born." 454

A tornado has killed one person in central Louisiana, authorities said Monday.Vernon Parish Sheriff's Office Chief Calvin Turner said authorities received a report of one fatality in a rural area of the parish, which is located northwest of Lafayette. Turner said the death was due to damage in a home. He didn't have any additional details.The National Weather Service earlier issued a tornado emergency, the highest criteria for a tornado warning, for Rapides Parish, east of Vernon Parish. This includes the town of Alexandria. A large tornado was confirmed near the Alexandria International Airport.Alexandria police said there are no reports of injuries in the parish. Several structures were damaged, police said.Video showed an overturned vehicle and debris in Alexandria.Tornado warnings and watches have been issued for parts of Louisiana, Mississippi, Arkansas and Texas, the 898
