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 new study shows that women who take birth control pills are less likely to develop the most aggressive types of ovarian cancer. "Among those who used the birth control pills, there were 46 percent lower odds of being diagnosed with ovarian cancer that resulted in death within 12 months of the diagnosis," Jennifer Mongiovi, a PhD student at the University at Buffalo and one of the authors of the study, said.The research also found over a five year period birth control pills reduced the likelihood fatal ovarian cancer by 32 percent. "By taking birth control pills, you can stop as much damage being done to your ovaries from your ovulation, and essentially lower your risk of future damage, such as cancer," Mongiovi said.However, researchers said that before you go out and buy birth control pills, you should consult with your doctor about your medical history and what is appropriate given your circumstances."With anything there are trade offs on both sides. Birth control is a hormone so you are potentially putting yourself at a greater risk of breast cancer. So that's something you definitely need to review your medical history. What essentially is the biggest risk to you," Mongiovi said.The research was conducted at Roswell Park. 1259

A new pop-up called The Kitten Lounge is now open in D.C. It gives cat lovers the chance to hang out with kittens, while giving them the opportunity to save lives. “Really, I would describe this place as your chic best friend’s apartment filled with cats, but it’s like cool and trendy," says Kanchan Singh, who created the pop-up lounge. At The Kitten Lounge, 25 kittens roam free. The kittens are between the ages of three and six months, and visitors pay to hang out and play or relax with them.Singh owns 521

A swing act performer fell during a Cirque du Soleil performance Sunday at the Bellagio hotel-casino in Las Vegas. The artist was part of the Russian swing act of "O," according to Ann Paladie, a spokesperson for the entertainment group. The show was stopped as a precaution measure while an emergency team brought the artist backstage following the show's response protocol. No immediate word was released to the extent of his injuries. However, Paladie said the artist would continue to be monitored by the medical and coaching teams to determine when he can return to his activities. The water-themed show is known to be one Cirque du Soleil's top-selling shows and has been a permanent residence at the Bellagio since 1998. 740
