9+ hour, 4+ min ago   (878+ words) What happens to Webb’s mysterious little red dots as the universe ages? The Saguaro galaxy’s red nucleus offers a way to explore their hidden surroundings. When the James Webb Space Telescope began finding tiny, intensely red sources in the early…...

13+ hour, 19+ min ago   (129+ words) Slate On this day in 2015 gravitational waves were detected for the first time by the Advanced LIGO interferometers in Louisiana and Washington state. The waves, predicted by Einstein’s general relativity, are caused by the rippling of spacetime caused by movement…...

23+ hour, 52+ min ago   (236+ words) Scientists using NASA's Chandra X-ray Observatory have discovered a new class of objects that behave differently from anything they have seen before. The newly spotted objects give off unusually low-energy X-rays but intense ultraviolet radiation, and scientists believe they could…...

1+ day, 6+ hour ago   (429+ words) Chariklo’s inner ring is getting denser. Its outer ring is fading. Both changes are happening at the same time — and, for the moment, nobody knows why. The finding matters beyond Chariklo itself. Ring systems around planets had already shown that…...

3+ day, 13+ hour ago   (477+ words) When two black holes find each other in the vastness of space, they can form a binary odd couple—and it’s more common than researchers expected. Scientists think most black holes are born when a star dies and its core…...

3+ day, 1+ hour ago   (715+ words) Brazilian physicist’s arXiv paper finds the two-phase warp sequence generates three simultaneous enemy-visible images, not the two depicted in TNG Shields failing, enemy closing fast, Jean-Luc Picard orders the USS Stargazer to punch to warp speed, stop cold near the…...

2+ day, 22+ hour ago   (635+ words) A new AI-powered reconstruction method has transformed radio observations into a continuous video, revealing unexpected motion inside a distant black hole jet. For decades, astronomers have relied on Very Long Baseline Interferometry (VLBI) to study the enormous jets launched by…...

2+ day, 20+ hour ago   (775+ words) New gravitational wave observatories could detect ancient black hole mergers and reveal how the first stars shaped the early universe. New generations of gravitational wave detectors could soon detect the hidden remnants of the universe’s first stars, according to a…...

4+ day, 6+ min ago   (418+ words) Astronomers once thought winds generated by supermassive black holes affected only their host galaxies, but a recent study found that their energy can also reach surrounding galaxies. Winds from a supermassive black hole can carry energy far beyond the galaxy…...
