Astronomers spot farthest galaxy ever, 13.5B light-years from Earth

Astronomers spot farthest galaxy ever, 13.5B light-years from Earth

Science
April 7 (UPI) -- A global team of astronomers has found the most distant space object ever, according to the Harvard-Smithsonian Center for Astrophysics. It's a distant galaxy called HD1, some 13.5 billion light years away from Earth, with researchers offering two ideas of what, exactly, the galaxy is. The first paper, published this week in the Monthly Notices of the Royal Astronomical Society Letters, is that HD1 could be creating stars at an astounding rate and could even be home to what's known as Population III stars. Population III stars are the universe's very first stars, which researchers say have never been seen until now. The second idea proposed by the team, in another paper published this week in the Astronomical Journal, is that HD1 could hold a supermassive black hole roug...
SpaceX successfully completes first launch of 2022 from Florida

SpaceX successfully completes first launch of 2022 from Florida

Science
ORLANDO, Fla., Jan. 6 (UPI) -- SpaceX kicked off a surge in launch activity Thursday with the successful launch of 49 of the company's Starlink communications satellites from Florida, heading south along the state's coastline. Five SpaceX missions may launch in the next month on the southern polar trajectory, flying closer to the Florida coast toward Miami than most launches, according to the U.S. Space Force. The Falcon 9 rocket lifted off as planned at 4:49 p.m. EST from Complex 39A at Kennedy Space Center. Nine minutes after launch, the first-stage booster landed successfully on a barge in the Atlantic Ocean. "Starlink is now live in 25 countries and regions currently servicing over 145,000 users worldwide," SpaceX engineer Jessie Anderson said during a live broadcast of the launch. "...
Appeal to identify ‘La Botaniste’ who slipped from history

Appeal to identify ‘La Botaniste’ who slipped from history

Science
RHSWhen sorting through books gathering dust in the attic, it's common to find mementos of the past such as a poem, a pressed-flower, or a letter.But when staff at the Royal Horticultural Society (RHS) went through hundreds of old plant books, they stumbled on a collection of botanical treasures the likes of which they'd never seen before.Tucked inside a copy of The English Flora from 1830 were poems, doodles, plant specimens and a cartoon.Judging by the contents, the owner was a keen plants woman. But her name, Isabella A Allen, appears to have slipped from history.She may be the early 19th Century botanical illustrator about which little is known. Or she could be among the legions of uncelebrated 19th Century women with a passionate interest in plants.Either way, the RHS is hoping to tra...
Owls may have inherited their night-hunting abilities from dinosaurs

Owls may have inherited their night-hunting abilities from dinosaurs

Science
May 6 (UPI) -- New research suggests a small bird-like dinosaur's exacting night vision and owl-like hearing allowed it to track down prey in the black of night. Nocturnal hunting is relatively rare among predators, as it requires specialized sensory abilities -- many of the best night-hunters are birds, including owls, nightjars, nighthawks and more. Advertisement Because modern birds are the closest living relatives of the dinosaurs, scientists have previously surmised that the night-hunting capabilities of owls and other nocturnal birds might be inherited from their theropod ancestors. To investigate the possibility, scientists used detailed CT scans to compare the anatomical features of the eyes and inner ears of nearly 100 living bird and extinct dinosaur species. They shared the re...
SpaceX Crew-1 astronauts to return to Earth from ISS

SpaceX Crew-1 astronauts to return to Earth from ISS

Science
ORLANDO, Fla., April 30 (UPI) -- The first operational crew of astronauts on a SpaceX orbital mission, Crew-1, plan to start their return to Earth on Friday after making history on a journey to the International Space Station. NASA plans to bring the crew of four home starting at 5:55 p.m. EDT, when the Crew Dragon capsule Resilience will undock from the space station. Advertisement After a relatively quick flight, the capsule is scheduled to splash down in the Atlantic Ocean near the coast of Florida at 11:36 a.m. Saturday. The flight marked the first time four people flew in a space capsule and was only the second crewed mission for SpaceX and NASA's commercial crew program. The capsule will fly automatically, or robotically, unless there is a serious problem, crew commander Mike Hopki...
