Reindeer herders in a Russian Arctic archipelago have found an immaculately preserved carcass of an Ice Age cave bear, researchers said Monday.
The find, revealed by the melting permafrost, was discovered on the Lyakhovsky Islands with its teeth and even its nose intact. Previously scientists only had been able to...
Hey, remember Betelgeuse? It caused quite a kerfuffle both among astronomers and normal people in late 2019 and early 2020 when the star's brightness dropped precipitously.

NASA engineers are laying the foundation for the moonwalks the first woman and next man will conduct when they land on the lunar South Pole in 2024 as part of the Artemis program. At the agency’s Johnson Space Center in Houston, teams are testing the tools and developing training...
Could the climate crisis drive Homo sapiens to extinction?

NASA is seeking proposals for two new private astronaut missions to the International Space Station as part of the agency’s efforts to open space to more people than ever before. With these opportunities, U.S. commercial companies will continue to play an essential role in establishing a sustained presence in...
A team of astronomers in Japan has detected 12 stellar flares, including a so-called superflare, on AD Leonis, an M-dwarf star located just 16 light-years away in the constellation of Leo.
“Stellar flares are sudden explosions that emanate from the surfaces of stars, including our own Sun,” said lead author...
Scientists have used high-speed video to capture a fleeting moment of connection that sets the path of a lightning flash.
A new study reports two consecutive images, each representing 1/380-thousandth of a second, illuminating how downward-questing lightning fingers from a lightning cloud, called lightning leaders, and upward reaching leaders from...
Researchers have discovered a treasure trove of data during the OSIRIS-REx mission, including the presence of water and traces of organic material, which may well seed life on planets such as our own across the galaxy.
According to Amy Simon, of NASA’s Goddard Space Flight Center, “carbon-bearing, organic material” is...
The U.S. Fish and Wildlife Service announced today that the interior least tern, a small bird that nests along major rivers in the midwestern and southern United States, has fully recovered and can be removed from the endangered species list.
Endangered Species Act protections have helped interior least tern numbers...
