For the first time, an object in our solar system has been found more than 100 times farther than Earth is from the sun.The International Astronomical Union's Minor Planet Center announced the discovery Monday, calling the object 2018 VG18. But the researchers who found it are calling it "Farout."They believe the spherical object is a dwarf planet more than 310 miles in diameter, with a pinkish hue. That color has been associated with objects that are rich in ice, and given its distance from the sun, that isn't hard to believe. Its slow orbit probably takes more than 1,000 years to make one trip around the sun, the researchers said.The distance between the Earth and the sun is an AU, or astronomical unit -- the equivalent of about 93 million miles. Farout is 120 AU from the sun. Eris, the next most distant object known, is 96 AU from the sun. For reference, Pluto is 34 AU away.The object was found by the Carnegie Institution for Science's Scott S. Sheppard, the University of Hawaii's David Tholen and Northern Arizona University's Chad Trujillo -- and it's not their first discovery.The team has been searching for a super-Earth-size planet on the edge of our solar system, known as Planet Nine or Planet X, since 2014. They first suggested the existence of this possible planet in 2014 after finding "Biden" at 84 AU. Along the way, they have discovered more distant solar system objects suggesting that the gravity of something massive is influencing their orbit.Farout was found using the Japanese Subaru 8-meter telescope on Hawaii's Mauna Kea in November. Follow-up observations with Carnegie's Las Campanas Observatory's Magellan telescope in Chile determined its path, brightness and color."This discovery is truly an international achievement in research using telescopes located in Hawaii and Chile, operated by Japan, as well as by a consortium of research institutions and universities in the United States," Trujillo said in a statement. "With new wide-field digital cameras on some of the world's largest telescopes, we are finally exploring our Solar System's fringes, far beyond Pluto."In October, the team announced the discovery of "the Goblin" at 80 AU; it's so named because the distant solar system object was first spotted near Halloween.It's unlikely that these objects are influenced by the gravity of gas giants Neptune and Uranus because they never get close enough to them -- which indicates that something else is determining their orbits.Farout's orbit is yet to be determined."2018 VG18 is much more distant and slower moving than any other observed Solar System object, so it will take a few years to fully determine its orbit," Sheppard said in a statement. "But it was found in a similar location on the sky to the other known extreme Solar System objects, suggesting it might have the same type of orbit that most of them do. The orbital similarities shown by many of the known small, distant Solar System bodies was the catalyst for our original assertion that there is a distant, massive planet at several hundred AU shepherding these smaller objects." 3114

HAMPTON, Va. - Hampton University's Mo'ne Davis took the country by storm in 2014, becoming the first girl to pitch a shutout in Little League World Series history. That performance led to another historic moment when Davis became the first Litte Leaguer to be featured on the cover of Sports Illustrated. Due to the stardom Davis experienced after making headlines as a 13-year-old, there was a lot of excitement when she decided to play softball at Hampton. “I was like oh snap," Hampton outfielder/first baseman Brianna Anderson said. "I was like oh this is big.” “When everyone found out she was coming it was kind of a cool deal, you know,” Hampton head softball coach Angela Nicholson said.Although, the position that earned her fame more than five years ago is now in the past for Davis.In fact, she won't even pitch to her teammates during practice, even though they ask to hit off her "like every day," Nicholson said.As a 13-year-old baseball player, Davis was pitching as fast as 70 miles per hour, but now she utilizes that arm strength at middle infield.“I wanted to keep hitting so I was like I'm just gonna play an field position," Davis said. “Her transition and her glove work is phenomenal, and that’s where you see the baseball side of things,” Nicholson said.The transition, early on, was accompanied with some uncertainty by the Pirates. The team was unsure what to expect from someone who experienced stardom at such a young age.“I thought the kid was gonna be arrogant or cocky, but it was complete opposite," Nicholson said. "If you didn’t know who she was it would never come out. She doesn’t speak of it. She just wants to be a normal everyday person.” “From the moment she stepped on campus she’s worked harder than everybody," Hampton pitcher Emily Workman said. "She just always gives it 110 percent.” Davis made her Pirates debut on Sunday, going 1-for-3 with a two-run single in Hampton's season opener against North Carolina A&T. The Pirates take the field again on Friday in Greenville, North Carolina, where they'll face George Washington University.This article was written by Megan Plain for 2145

For the fourth time in just over a week, losses by the Dow Jones Industrial Average triggered a circuit-breaker.The Dow had dropped 7 percent by early afternoon Wednesday, and trading was halted for 15 minutes.At the time of the trading halt, the Dow had fallen below where it had been when President Donald Trump was inaugurated in January 2017.The drop came after futures fell sharply overnight, signaling a tough day ahead for markets.By the end of the day, the Dow leveled off, closing down 6.3% for the day, losing 1,333 points from yesterday's totals. The Dow closed below, 20,000 points for the first time in more than three years. The Dow Jones Industrial Average has fallen 28 percent since hitting its all-time high in February.On Tuesday, the Dow recovered slightly from historic losses on Monday on the back of President Donald Trump's talk of a stimulus plan. Trump and administration officials said they are considering sending Americans cash directly within a matter of weeks in an attempt to boost the economy amid quarantines caused by the coronavirus pandemic. 1090

  

Greyhound has been put up for sale after its UK owner caved to activist investors who wanted the company to ditch the bus line.FirstGroup, which owns the iconic inter-city bus operation, said Thursday that it wants to focus on its school transportation and commuter businesses.The company said in a statement that Greyhound has "limited synergies" with its other businesses in North America and that "value for shareholders can best be delivered by seeking new owners.""Our plans will create a more focused portfolio, with leading positions in our core North American contracting markets," added CEO Matthew Gregory.The company owns American school bus service First Student, which it says is the largest in North America. Its First Transit brand offers shuttle buses and other services to commuters in the United States.FirstGroup said the two divisions generate a combined 60% of the its operating profits and increasingly overlap in terms of the technologies and skills they require. Shares in FirstGroup surged almost 5% in London after the announcement.Greyhound said it serves 2,400 destinations across the United States and Canada, transporting nearly 16 million passengers each year.The separation is a big win for activist shareholder group Coast Capital Management, which owns just under 10% of FirstGroup.Coast Capital Management had been pushing FirstGroup's board to separate its businesses in the United Kingdom and North America.The investor group said that while it welcomed the plan announced Thursday, it still wants to take control of FirstGroup's board by replacing six of the current 11 directors.Coast Capital said it has "no confidence in the ability of the current board to deliver the changes needed to best effect, as there is precious little expertise in surface transport among the current lineup, especially in a US context." 1866
