The Labor Department saw an additional 3 million people seeking unemployment claims last week — the highest increase of unemployment claims the Labor Department has recorded since it began measuring seasonal unemployment.It also marked the highest level of insured unemployment since April 2018, when the unemployment rate was at 342
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 moon is slowly shrinking over time, which is causing wrinkles in its crust and moonquakes, according to photos captured by NASA's Lunar Reconnaissance Orbiter.Unlike Earth, the moon doesn't have tectonic plates. Instead, as the moon's interior has cooled over the last several hundred million years, it has caused the surface to wrinkle as it shrinks. Unlike the flexible skin of a grape when it shrinks into a raisin, the moon's brittle crust breaks. This creates stair-step cliffs called thrust faults as part of the crust is pushed up and over another close part of the crust.There are now thousands of cliffs scattered across the moon's surface, averaging a few miles long and tens of yards high. The orbiter has taken photos of more than 3,500 of them since 2009. In 1972, Apollo 17 astronauts Eugene Cernan and Harrison Schmitt had to ascend one of these cliffs, the Lee-Lincoln fault scarp, by zig-zagging the lunar rover over it.Today the moon is 50 meters "skinnier" because of this process. And as it shrinks, the moon actively produces moonquakes along the faults. Researchers re-analyzed seismic data they had from the moon to compare with the images gathered by the orbiter.Data from the seismometers placed on the moon during the Apollo 11, 12, 14, 15 and 16 missions revealed 28 moonquakes recorded between 1969 and 1977. Researchers compared the location of the epicenters for those quakes with the orbiter imagery of the faults. At least eight of the quakes occurred due to activity along the faults. This rules out the possibility of asteroid impacts or rumblings from the moon's interior.This means that the Apollo seismometers recorded the moon shrinking, the researchers said. The study of Apollo seismic data and analysis of more than 12,000 of the orbiter's photos were published Monday in the journal 1841
The Dow Jones Industrial Average closed the week on a sour note, giving back some of the gains it had made on three straight days in the green.The Dow closed down 915 points — a 4 percent loss — its first drop since Monday. However, the markets remained up for the week, the first week-over-week gain since February.The day of losses came despite the House passage of a .2 trillion stimulus package that the Trump administration hopes can boost the economy amid an economic slowdown caused by the coronavirus. President Donald Trump is expected to sign the bill into law this afternoon. 600
