The scene looks delicate, but it belongs to one of the oldest classes of objects in the Milky Way. Inside its crowded glow, astronomers see evidence that this stellar “chandelier” formed through…

Researchers at Monash University have found that Antarctica’s current ice loss can reveal how much the continent is likely to add to sea levels over the next 30 to 50 years. The study, published in Nature, suggests that models matching today’s observed ice loss can give governments and coastal planners a stronger basis for decisions…
A study in Science Advances has found that the Moon’s enormous South Pole-Aitken basin may have been carved by a 260-kilometer differentiated impactor that struck from north to south. If the models are right, future Artemis astronauts near the lunar south pole could encounter rocks that began deep inside the Moon. The work focuses on…
A study in Earth and Planetary Science Letters has found evidence that a rare meteorite from the Sahara Desert came from a shattered protoplanet that may have been as large as the Moon. The finding points to a vanished world that formed during the solar system’s infancy, then broke apart after a violent collision. The…
