1+ day, 8+ 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…...

3+ day, 14+ hour ago   (618+ words) Using a next-generation telescope, astronomers investigated two distant sources that had puzzled researchers and found evidence pointing to a much more complex story. The James Webb Space Telescope has revealed that two mysterious objects from the early universe were not…...

3+ day, 15+ hour ago   (231+ words) Astronomers have reconstructed a massive protostellar encounter that could reveal an unexpected route to building close binary stars. Astronomers have reconstructed the turbulent assembly of two massive young stars, finding evidence that they may have formed separately before a close…...

4+ day, 11+ hour ago   (671+ words) NASA’s Hubble and Webb telescopes have revealed that tiny objects beyond Neptune may preserve the earliest history of planet formation. NASA’s Hubble Space Telescope and James Webb Space Telescope have revealed that some of the smallest objects beyond Neptune still…...

4+ day, 15+ hour ago   (522+ words) This strange cosmic structure looks like a giant eye in space, but astronomers discovered that the Helix Nebula is actually a massive cylinder of glowing gas pointing toward Earth. A new portrait of the Helix Nebula offers one of the…...

4+ day, 11+ hour ago   (762+ words) Scientists have uncovered a new approach to reading black hole signals, but the strange possibility behind the pattern remains one of the biggest mysteries. Black holes may hide structures that cannot be seen directly but could leave traces in gravitational…...

1+ week, 2+ day ago   (654+ words) Astronomers have identified the violent merger that launched a supermassive black hole out of its galaxy and into intergalactic space. In 2022, astronomers detected an unusual structure extending from a distant galaxy located about 7.5 billion light-years from Earth. The feature appeared…...

1+ week, 2+ day ago   (463+ words) A weird spacetime crystal has scientists looking at gravity in a whole new way, and the results are stranger than expected. Unlike the massive black holes found at the centers of galaxies or created by collapsing stars, these theoretical objects…...

1+ week, 3+ day ago   (675+ words) A supermassive black hole in the Perseus Cluster revealed a rare link between X-ray activity and delayed radio jets. A supermassive black hole in the galaxy NGC 1275 erupted in X-rays before triggering a radio flare nearly 300 days later, revealing a…...

1+ week, 4+ day ago   (642+ words) JWST has identified a distant supernova that reveals how massive stars ended their lives in the young universe. The light from SN 2023aeaf has traveled for roughly 11.7 billion years before reaching Earth, carrying information from an era when galaxies were still…...
