A ten-sided atmospheric wave is circling Saturn's south pole, according to a paper published Sept. 2 in Science Advances by Agustín Sánchez-Lavega of the University of the Basque Country and…

Astronomers have identified four candidate pairs of "little red dots" in the James Webb Space Telescope's COSMOS-Web survey, and follow-up spectroscopy places both members of two of those pairs at…

Mars's atmosphere is stirred by a single planet-wide loop of circulation, and a new analysis reports that the loop's own structure keeps dust and gas from mixing across its edge while carrying…

The Japan Meteorological Agency will begin feeding observations from a microwave sensor aboard a Japanese satellite launched last year into the computer model that underpins its public weather…

Researchers at Arizona State University and two partner institutions tumbled stony meteorites in a laboratory mill and measured how long each took to fall apart. The number of rotations needed to…

NASA astronaut Jessica Meir and ESA astronaut Sophie Adenot ended a spacewalk outside the International Space Station at 3:29 p.m. EDT on Sept. 1 after installing a new navigation reflector on the…

MIT researchers report that three short peptides stayed intact for weeks in a solution of about 98 percent sulfuric acid and folded into a defined three-dimensional shape instead of breaking down.…
