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 body of a missing Texas police chief who fell overboard while on a fishing boat was recovered Sunday morning, the US Coast Guard said.Kemah Police Chief Chris Reed was on the boat with his wife in Galveston Bay on Friday afternoon when it was hit by a wake of a passing vessel.His body was found about 8 a.m. a mile and a half north of the Texas City Dike in Texas City, the Coast Guard said.Reed's wife remained on the boat and was not injured. He was not wearing a life jacket at the time, Coast Guard Lt. Cmdr. Caren Damon told reporters.Kemah is on Galveston Bay about 40 miles from Houston.Coast Guard crews searched more than 650 square miles over some 40 hours.About 40 vessels, including 15 from the Coast Guard, searched, the Coast Guard said. An aircrew and a team of drones -- along with 12 state, local and federal agencies -- were involved, said Tom Munoz, emergency management coordinator for Texas City."Number one, he's just a great cop, just to start off with. He's been in this county a long time, working for several different agencies," said Texas City Police Chief Joe Stanton before the body was located. "We're a tight-knit group. He's one of ours. And, we're out there and we're gonna find him."In addition to his career as a police officer, Reed was a retired Army paratrooper and was on the Clear Creek Independent School District board, according to CNN affiliate 1407

The family of a man who contracted COVID-19 on the Grand Princess and later died is suing Princess and Carnival Cruises, saying the companies should have known passengers on board were sick and should not have accepted more passengers.64-year-old Ronald Wong and his wife boarded the Grand Princess in March in San Francisco, Mexico. A month later, Wong died in a California hospital after testing positive for coronavirus.Wong's wife also contracted the virus, but later recovered.In the lawsuit, Wong's family claims the cruise line and its parent company should have known a passenger on the ship's previous voyage had tested positive for COVID-19.After reports emerged that several passengers had contracted the virus, the Grand Princess docked at the Port of Oakland on March 9. A total of 131 people aboard the ship tested positive for the coronavirus, and five later died. The lawsuit filed by Wong's family is one of roughly a dozen filed by passengers on the Grand Princess and their families.A spokesperson for Princess Cruises said the company does not comment on pending litigation. 1106
