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 York jury granted nearly million in civil damages to a high school student who was severely burned in a 2014 class chemistry experiment.The award is the culmination of a years-long lawsuit by the family of Alonzo Yanes, who was a student at New York's Beacon High School at the time of the experiment.Yanes is still being treated for his injuries, requiring autografts to replace tissue, his lawyer said."He hasn't had a day without pain," lawyer Ben Rubinowitz said. "They are more than just scars on his face."The lawsuit accused the New York City Department of Education and the Board of Education of failing to alert teachers to the dangers of the experiment, known as the rainbow demonstration.The experiment was intended to demonstrate colors of flame produced by the combustion of various metals or salts. When Yanes attempted it in his sophomore chemistry class, it generated an explosion that caused a fire, the lawsuit states.Several months after the incident, the American Chemical Society's Committee on Chemical Safety put out a 1064

After decades of silence, one of perhaps hundreds of sexual misconduct victims of an Ohio State University team doctor is speaking out for the first time, hoping his story serves as a lesson.The numbers are staggering: nearly 50 instances of rape, almost 1,500 cases of fondling.Those new numbers detail how widespread sexual abuse was at the hands of an Ohio State University's Dr. Richard Strauss. Many of the accusers are former OSU athletes.One of those shared the story he kept hidden for decades.For 14 years, he's been a trusted name in Grand Rapids, Michigan. But for years, Mike Avery, 607

Actress Katherine Helmond was a TV sitcom star in the 70s and 80s and continued acting well into her 80s before succumbing to complications from Alzheimer’s disease last week at the age of 89, Variety Magazine reported.

"Who's the Boss" was one of the most popular sitcoms of the 80s, and was consistently one of the 10 most watched TV shows on TV. For her part playing Robinson, Helmond earned a Golden Globe Award, and a pair of Emmy nominations. Helmond played also played a comedic role on the sitcom "Soap" from 1977 to 1981. The sitcom was a spoof on daytime soap operas. She also won a Golden Globe for her role on "Soap."Before her two breakout TV comedy roles, Helmond appeared in a number of films as well as taking on walk-on roles on TV shows. In 1973, she was nominated for her performance in the Broadway drama "The Great God Brown." 1220

A New Zealand island volcano vented more steam and mud Wednesday, prompting authorities to delay plans to recover the bodies of victims from a deadly eruption two days ago.Volcanic tremors on White Island were intensifying to a level not seen since an eruption in 2016, the GeoNet seismic monitoring agency said, calculating a 40% to 60% chance of another eruption within the next 24 hours.Meanwhile, Australia was sending a military plane to bring some of the Australians injured in the eruption to Australia for specialist medical care. Authorities expected to transport 10 injured patients to New South Wales and Victoria states, beginning Thursday.Six deaths have been confirmed in Monday’s eruption, which sent a tower of steam and ash an estimated 12,000 feet (3,660 meters) into the air. The bodies of eight other people are believed to remain on the ash-covered island. And 30 people remain hospitalized, including 25 in critical condition. Many of the injured suffered severe burns and were being treated at hospital burn units around New Zealand.GeoNet said in an early evening update that shallow magma within the volcano appeared to be driving the increased activity. It also said there was a low risk to the mainland. The volcano is about 50 kilometers (30 miles) off New Zealand’s main North Island.Police believe 47 visitors were on the island at the time of the eruption, 24 of them Australian, nine Americans, five New Zealanders and others from Germany, Britain, China and Malaysia. Many were passengers aboard the Royal Caribbean cruise ship Ovation of the Seas. Survivors ran into the sea to escape the scalding steam and ash and emerged covered in burns, said those who first helped them. Geoff Hopkins watched the eruption from a boat after visiting the island and told the New Zealand Herald the eruption quickly turned menacing.He told the paper that injured people transported on their boat were horrifically burned on their exposed skin and even under their clothes.The first confirmed death was of a local man, Hayden Marshall-Inman, a guide who had shown tourists around the island. Former Whakatane Mayor Tony Bonne said Marshall-Inman was a keen fisherman and well-liked. In the town touted as the gateway to White Island, the volcano has an almost mystical significance, its regular puffing a feature of the landscape. Whether the island, also known by its Maori name Whakaari, will ever host tourists again remains uncertain. Many people were questioning why tourists were allowed to visit the island after seismic monitoring experts raised the volcano’s alert level last month. The island had been mined for sulfur until a 1914 accident in which at least 10 people were killed, and a landslide destroyed the miners’ village and the mine itself. The island became a private scenic reserve in 1953. Daily tours allow more than 10,000 people to visit every year. 2904
