Aug. 27 (UPI) — NASA observed interstellar comet 3I/ATLAS through the lens of the James Webb Space Telescope for the first time. On Aug. 6, the telescope with its near-infrared Spectrograph instrument analyzed the comet as it provided more information about its size, physical properties, and chemical makeup. This kind of observation can help make clear what conditions were like …

Chemistry that cools clouds The first star-forming gas clouds, called protostellar clouds, were warm—roughly room temperature. Warm gas has internal pressure that pushes outward against the inward force of gravity trying to collapse the cloud. A hot air balloon stays inflated by the same principle. If the flame heating the air at the base of the balloon stops, the air …

Tank-like physique, bristling with body armour and a collar of spikes the length of golf clubs, Spicomellus afer looks more like a Pokémon creation than a living creature. This bizarre dinosaur roamed the flood planes of what is now north Africa 165m years ago, palaeontologists have revealed. The fossil, the oldest known ankylosaur specimen, was unearthed near the central Moroccan …

Volcanoes can bring catastrophic consequences, and reliable warnings can make the difference between a close call and a tragedy. A new study on Japan’s Ontake Volcano identifies a signal, in the form of a subtle change in earthquake waves, that could sharpen those warnings. Researchers compared two eruptions of Ontake and focused on a detail in the waves …

Recent studies have revealed fascinating connections between rising oxygen levels in deep-ocean environments and the evolution of marine life, particularly in the Late Devonian period. This research, published in the Proceedings of the National Academy of Sciences, uncovers how oxygenation, driven by terrestrial plant growth, may have shaped the future of life in the ocean. These findings help us understand …
