Dec 3rd, 2025 - Planned orbital observatories would see satellites cross nearly all of their images. On Wednesday, three NASA astronomers released an analysis showing that several planned orbital telescopes would see their images criss-crossed by planned satellite constellations, such as a fully expanded Starlink and its competitors. While the impact of these constellations on ground-based has been widely considered, orbital hardware was thought to be relatively immune from their interference. But the planned expansion of constellations, coupled with some of the features of upcoming missions, will mean that ... [Read More]

Dec 3rd, 2025 - As U.S. electricity demand rises and technology companies seek to build more and larger data centers to drive artificial intelligence systems, the main question arising is how to generate all that power. According to the International Energy Agency, large-scale data centers around the world used about 460 terawatt-hours of electricity in 2022, a figure that analysts expect to continue rising years into the future. One potential solution being proposed is nuclear energy – produced by existing large-scale nuclear power plants , reactivated old ones , new ones that might be constructed ... [Read More]

Dec 2nd, 2025 - What appeared to be tentacles washed up on an Aberdeenshire beach are the remains of a deep-sea creature called a seven-arm octopus, say experts. A local member of the public spotted the arms with rows of suckers at Forvie National Nature Reserve at Collieston, near Ellon, on Sunday and alerted reserve staff. Detective work led to the animal being identified as one of the world's largest species of octopus - although experts remain puzzled about how it washed up on the beach. Also known as a septopus, giant gelatinous octopus or blob octopus, they have eight arms like other octopus - but in ... [Read More]

Dec 2nd, 2025 - One of the mantras of amateur astronomy is ''aperture rules.'' This means you'll see more detail as you observe through ever-larger telescopes. Few celestial objects demonstrate this better than Stephan's Quintet. So, fair warning, this post is directed to those of you with access to large amateur instruments. French astronomer Edouard Stephan discovered this group in 1877 in the constellation Pegasus the Winged Horse. The five galaxies now carry the designations NGC 7317 (magnitude 14.6), NGC 7318A (magnitude 14.3), NGC 7318B (magnitude 13.9), NGC ... [Read More]

The enormous snakes' average body size has remained constant since they first appeared in the fossil record about 12.4 million years ago, during the Middle Miocene (16 million to 11.6 million years ago), researchers revealed in a new study published Monday (Dec. 1) in the Journal of Vertebrate Paleontology . During the ... [Read More]

Duchêne Day 2 of the 2025 Space Telescope Advent Calendar : a stellar nursery. Reflection nebula GN 04.32.8 is part of the stellar nursery called the Taurus Molecular Cloud, roughly 480 light-years from Earth. Enormous clouds of dust surround a group of chaotic young stars, illuminated by their starlight. The small orange blob to the right of center is a newly formed protostar, hidden in a protoplanetary disk that obstructs some of its light, ... [Read More]

Dec 2nd, 2025 - You can now listen to Fox News articles! Archaeologists have opened the lid on a rare, untouched Roman sarcophagus in Hungary — the first time it's been opened in 1,700 years. The tomb, discovered by archaeologists with the Budapest History Museum, was found in Óbuda, a northern district of Budapest. Óbuda was known as Aquincum in Roman times, serving as a major settlement located on the banks of the Danube River. The tomb was found in a 3rd-century burial ground, among the ruins of abandoned houses. Remarkably, the tomb hadn't been opened by looters since it was buried. ... [Read More]
