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 massive police response converged on the small town of Huger, South Carolina Tuesday afternoon following reports of an active shooter, ending in a shootout with officers that left the suspect dead. Berkeley County Sheriff's Office confirmed that no other injuries stemmed from Tuesday's incident. The Sheriff's Office tweeted a photo of one its cruisers that was targeted by the suspect. The suspect's identity has not been released. 448

America's longest war may finally be nearing an end. More than 18 years after the Afghanistan conflict began in response to the September 11, 2001, attacks, the United States and the Islamists it toppled from power in Afghanistan are poised to sign a peace deal on Saturday. That will set the stage for the withdrawal of U.S. troops, some of whom were not yet born when the World Trade Center collapsed. And it promises the potential end of a tremendous American investment of blood and treasure. Negotiations among Afghan factions are still to come. 563

An AK-47 style rifle legally purchased in Nevada and used to attack people at the Gilroy Garlic Festival in northern California couldn't have been purchased legally in California, state Attorney General Xavier Becerra said Monday.Becerra said it's also illegal to transport the assault-style weapon into the state."That weapon could not be sold in California. That weapon cannot be imported into the state of California," Becerra said in response to a question about the assault-style rifle used in the shooting.Becerra added: "There is a very strong likelihood as we develop the evidence that the perpetrator in this particular case violated California law on top of the crimes of homicide and so forth, the crimes that we have that are meant to prevent individuals from carrying out this type of activity."Santino William Legan, 19, killed three people and injured at least 12 others at festival on Sunday with the rifle he bought July 9 in neighboring Nevada, Gilroy Police Chief Scot Smithee told reporters Monday. Three officers who responded within a minute of the gunfire fatally shot Legan, he said.Legan apparently entered the annual festival, which attracts about 100,000 people every year, by using a tool to cut through a back fence and then 1266

After a widely-panned debate performance highlighted by former NYC Mayor Michael Bloomberg getting taken to task by Sen Elizabeth Warren and others about bounding employees of Bloomberg to nondisclosure agreements, Bloomberg said Friday he will release several employees from their NDAs if asked. In a tweet published on Friday, Bloomberg stated, “Bloomberg LP has identified 3 NDAs signed over the past 30+ years with women to address complaints about comments they said I had made. If any of them want to be released from their NDAs, they should contact the company and they'll be given a release.”Bloomberg added, “I’ve decided that for as long as I’m running the company, we won’t offer confidentiality agreements to resolve claims of sexual harassment or misconduct going forward.”Warren hammered Bloomberg for his refusal to release some of his employees from their nondisclosure agreements."Are the women bound by being muzzled by you? You could release them from that immediately. Because understand, this is not just a question of the mayor's character," Warren said."We have very few nondisclosure agreements. None of them accuse me of doing anything other than maybe they didn't like a joke I told," he responded.One of the "jokes" Bloomberg could be referring to is 1290
