Supreme Court Chief Justice John Roberts was sworn in Thursday to preside over impeachment trial of President Donald Trump on Thursday, beginning the third impeachment trial in U.S. history.House lawmakers prosecuting the case began Thursday by walking across the Capitol and formally delivering the articles in the Senate chambers.Roberts then swore in all senators, who will act as jurors during the impeachment trial.Rep. Adam Schiff (D-California), one of the impeachment managers appointed by House Speaker Nancy Pelosi, then read the articles in their entirety. The articles allege Trump abused his presidential power by pressuring Ukraine to investigate Democratic rival Joe Biden and used military aid to the country as leverage. Trump is also charged with obstructing Congress’ ensuing probe.Watch live video of the swearing-in below.Trump has called the impeachment a "hoax." 897

Snowball can headbang, vogue and body roll as well as, if not better than, any rhythmically inclined human. Never mind he's covered in feathers.The sulphur-crested cockatoo broke big on YouTube in 2007 for his toe-tapping, head-bobbing performance to the Backstreet Boys' "Everybody." But after spending a decade studying his wide repertoire of bangs, hops and lifts, researchers suggest that parrots and humans share a tendency to dance when the music moves them.Ever the entertainer, Snowball performed 14 unique dances when prompted by music, according to findings published Monday in Current Biology. It's evidence that some birds are capable of sophisticated cognitive control and a level of creativity previously unseen in other species.The study follows a 775

SpaceX launched 60 more mini internet satellites late Monday, this time testing a dark coating to appease stargazers.It’s a “first step” compromise between SpaceX and astronomers fearful of having dark skies spoiled by hundreds and, eventually, thousands of bright satellites circling overhead.The Falcon 9 rocket blasted into a cold, clear night sky, recycled by SpaceX for its fourth flight. As the first-stage booster flew to a vertical landing on an ocean platform, the Starlink satellites continued hurtling toward orbit to join 120 similar spacecraft launched last year. Flight controllers applauded, and the launch commentator described the booster’s fourth touchdown as “awesome.” An hour later, all 60 satellites were free of their upper stage and making their own way in orbit. “It’s a beautiful sight,” the commentator observed.His Starlink fleet now numbering 180, SpaceX founder and chief executive Elon Musk plans to ultimately launch thousands of these compact flat-panel satellites to provide global internet service. Each spacecraft is just 575 pounds (260 kilograms).After the first Starlink batch of 60 was launched in May and the second in November, astronomers complained how the bright satellite chain was hampering their observations. In response, SpaceX came up with a darkening treatment to lessen reflectivity. The coating is being tested on one of the newly launched satellites.Jeff Hall, director of the Lowell Observatory in Flagstaff, Arizona, said the Starlinks have been just an occasional problem — so far — but noted the risk to stargazing will grow as the constellation expands and other companies launch their own fleets. He heads the American Astronomical Society’s committee on light pollution, space debris, and radio interference, and is working with SpaceX on the issue. The matter is on the agenda, in fact, at the society’s conference in Hawaii this week.“Anything that darkens the satellites is a step in the right direction,” Hall said in an email Monday. He said it’s too soon to know whether the dark coating will work, “but it definitely is just a first step and not enough to mitigate the issues astronomy will experience with the Starlinks.”The Starlinks are initially placed in a relatively low orbit of 180 miles (290 kilometeters), easily visible as a long, strung-out cluster parading through the night sky. Over a few months, krypton-powered thrusters raise the satellites to a 340-mile (550-kilometer) orbit. The higher the orbit, the less visible the satellites are from the ground, according to SpaceX. Even so, SpaceX said it’s supplying astronomy groups with the satellite coordinates in advance, so they can avoid the bright flyover times.Already established in launching satellites for others and making space station deliveries for NASA, SpaceX is among several companies looking to provide high-speed, reliable internet service around the world, especially in places where it’s hard to get or too expensive. Others include Jeff Bezos’ Amazon and OneWeb. SpaceX may start service later this year in the northern U.S. and Canada, then expand to the world’s most populated areas after 24 launches. 3170

Rep. Steve King, the Iowa Republican who was stripped of his congressional committee assignments earlier this year, was not allowed to fly aboard Air Force One on Tuesday as President Donald Trump traveled to Iowa, two GOP officials say.King, who represents the state's 4th District in Western Iowa, asked the White House to join the President's entourage, but administration officials rejected the request, two officials familiar with the matter told CNN.Republican Sens. Joni Ernst of Iowa and Deb Fischer of Nebraska joined Trump aboard Air Force One. Ernst had not been planning to travel with the President, citing her voting schedule, but ended up flying to Iowa with Trump.King declined to comment about the snub, telling CNN on Wednesday morning that he had nothing to say about the matter.Instead of cruising back to Washington on Air Force One, King buckled himself into seat 1A and sipped a cup of coffee on an American Airlines flight back to the nation's capital.He attended the Republican Party of Iowa's fundraising dinner in West Des Moines on Tuesday evening. He faces a primary challenge in his re-election bid next year.While King has a history of making incendiary remarks around race and immigration, King was removed from his committee assignments and rebuked by members of his own party after giving an interview with The New York Times in January in which he made racist comments. In the article, King, as part of a defense of what he said was the "culture of America," asked how certain terms had become controversial in modern discourse."White nationalist, white supremacist, Western civilization — how did that language become offensive?" he told the Times. "Why did I sit in classes teaching me about the merits of our history and our civilization?"King said on the House floor in January that he rejected the ideology of white nationalism and he maintains that his comments were misinterpreted. The House Republican Steering Committee removed King from his committee posts shortly after the comments were publicized in January.Despite the controversy, King refused to step aside from his post in Congress and announced in February he'll run for re-election in 2020. He won his race in 2018 by 3.6 percentage points. 2256
