The most distant world ever explored 4 billion miles away finally has an official name: Arrokoth.That means “sky” in the language of the Native American Powhatan people, NASA said Tuesday.NASA’s New Horizons spacecraft flew past the snowman-shaped Arrokoth on New Year’s Day, 3 ? years after exploring Pluto. At the time, this small icy world 1 billion miles (1.6 billion kilometers) beyond Pluto was nicknamed Ultima Thule given its vast distance from us.“The name ‘Arrokoth’ reflects the inspiration of looking to the skies,” lead scientist Alan Stern of Southwest Research Institute said in a statement, “and wondering about the stars and worlds beyond our own.”The name was picked because of the Powhatan’s ties to the Chesapeake Bay region.New Horizons is operated from Johns Hopkins University’s Applied Physics Lab in Laurel, Maryland. The Hubble Space Telescope — which discovered Arrokoth in 2014 — has its science operations in Baltimore.The New Horizons team got consent for the name from Powhatan Tribal elders and representatives, according to NASA. The International Astronomical Union and its Minor Planet Center approved the choice.Arrokoth is among countless objects in the so-called Kuiper Belt, or vast Twilight Zone beyond the orbit of Neptune. New Horizons will observe some of these objects from afar as it makes its way deeper into space.___The Associated Press Health and Science Department receives 1436

The grand jury's criminal investigation started by special counsel investigators is "continuing robustly," a federal prosecutor said Wednesday, even though Robert Mueller filed his report on Russian interference in the 2016 election with the Justice Department last week.In a federal court hearing about whether the name of the company and country that's been fighting a subpoena from Mueller since last summer should be revealed, Chief Judge Beryl Howell asked prosecutor David Goodhand, point-blank, if the grand jury investigation is over."No, it's continuing. I can say it's continuing robustly," said Goodhand, an assistant prosecutor in the DC US attorney office.There were no prosecutors from Mueller's office in court. The special counsel's office has handed over the subpoena case to the DC US attorney's office. It remains unclear what part of Mueller's investigation is ongoing and if more criminal charges could still come.The continuing work, even after Mueller declared his investigation had concluded, further raises questions about what was being investigated with few clues so far about what country it is or the company, which the special counsel has previously said is not a target of the investigation but has information needed by prosecutors.Attorney General William Barr wrote in his letter to Congress that several matters had been referred by Mueller to other federal prosecutor offices.The hearing was held to discuss whether the name of the company and other details could be made public. The company does not want its identity revealed, its lawyers said in court.Howell did not make a decision Wednesday, but acknowledged that it would be harder under the law to reveal the company's identity if there continues to be an active investigation. 1782

The first three nomination races have not gone well for former Vice President Joe Biden. The once frontrunner for the Democratic nomination has struggled to attract voters to the polls thus far. But Saturday’s primary in South Carolina could be what the doctor ordered for an ailing campaign. Or it could be what brings the campaign to a halt going into Super Tuesday. POLLS CLOSE AT 7 P.M. ET ON SATURDAY.South Carolina represents the most delegates (54) that have been up for grabs in a nominating race so far. It is also far more diverse than Iowa and New Hampshire. While Biden was hopeful a more diverse electorate would improve his fortunes in Nevada, he watched as Sen. Bernie Sanders won in convincing fashion last week. Still, Nevada was Biden’s best performance of the three races so far, but his second-place finish only showed how much ground he has lost to Sanders. DELEGATE COUNT THROUGH FEB. 28:SANDERS: 45BUTTIGIEG: 26BIDEN: 15WARREN: 8KLOBUCHAR: 71991 NEEDED TO WIN THE NOMINATIONPolling for Saturday’s primary indicates South Carolina could put Biden back into the mix as Democrats prepare for the most important night of the nomination on Tuesday. Monmouth University released a South Carolina primary poll on Thursday indicating Biden was leading the pack with 36%. The poll showed that Sanders and Tom Steyer were jockeying for second with 16% and 15% respectively. 15% is a key figure for the race as it is the threshold to receive delegates – anything less results in a goose egg. Helping Biden’s standing with the black vote was this week’s endorsement from Rep. Jim Clyburn. Clyburn, the third-most powerful Democrat in the House, has been one of South Carolina’s most recognizable Democrats for decades. “I know Joe Biden. I know his character, his heart, and his record. Joe Biden has stood for the hard-working people of South Carolina. We know Joe. But more importantly, he knows us,” Clyburn told voters this week. Following Saturday’s race is Super Tuesday when one-third of all delegates are up for grabs. The night could be intriguing for several reasons. One is the foray of Mike Bloomberg into the race. He sat out the first four nominating contests, and has spent a fortune of his own money to advertise in delegate-rich states such as Texas and California. Super Tuesday also could provide clarity on which candidate or candidates will take on Sanders deep into the nominating race. Finally, it could give an indication on whether Democrats need to prepare for a brokered convention. As Democrats allocate delegates proportionally, having a candidate such as Sanders come away with a majority of the delegates by July's convention could be a challenge. 2701

The House moved toward approval of a non-binding measure limiting President Donald Trump's ability to take military action against Iran as criticism of the U.S. killing of a top Iranian general intensified. Speaker Nancy Pelosi, D-Calif., said that while the war powers resolution does not require Trump's signature, it nonetheless “has real teeth” because it is “a statement of the Congress of the United States.''Republicans denounced the House measure as little more than “a press release” designed to attack Trump. Trump and Vice President Mike Pence urged GOP lawmakers to oppose the plan.Correction: This story has been updated to reflect that the House is nearing a vote and has not yet passed a resolution.
