A New Catalog of Close to 3,000 Supernova Challenges Theories on Dark Energy
4+ hour, 1+ min ago (88+ words) The most comprehensive catalogue of exploding white dwarf stars ever assembled has revealed new clues about dark energy, the mysterious force driving the universe’s accelerating expansion....
A molecular-hydrogen cloud only 300 light-years away spans roughly 40 full-Moon widths across our sky, yet astronomers did not identify it until 2025. Named Eos, it escaped conventional surveys because they search for molecular hydrogen indirectly through carbon monoxide—and almost all of Eos is CO-dark.
5+ hour, 25+ min ago (858+ words) Eos covers about 20 degrees of sky, but almost all its estimated 3,400 solar masses of molecular hydrogen escaped the carbon-monoxide surveys normally used to find such clouds....

‘Odd couple’ black holes can find each other in space
2+ day, 2+ 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…...
Help Refine Data from Space Telescopes with Artifact InSPECtor
1+ day, 10+ hour ago (186+ words) How do scientists studying space with data from a telescope hundreds of thousands of miles away know that what they are seeing is real? A new NASA project, Artifact InSPECtor, invites you to find out – and by doing so, to…...
Astronomy Picture of the Day - M83: The Southern Pinwheel
1+ day, 10+ hour ago (312+ words) Explanation: Beautiful and bright spiral galaxy M83 lies some twelve million light-years away, near the southeastern tip of the very long constellation Hydra. Prominent spiral arms traced by dark dust lanes and blue star clusters lend this galaxy its popular name,…...
