Astronomers mining NASA’s Chandra archive found 84 previously overlooked “hypersoft” sources across six galaxies, including Andromeda, that appear to emit most of their enormous energy in extreme ultraviolet—radiation that could ionize interstellar gas and influence how quickly galaxies form stars. They remained hidden because their X-rays fall almost entirely below 0.3 keV, while intervening gas absorbs their ultraviolet light.
2+ day, 3+ hour ago (761+ words) A Chandra archive search found 84 sources visible almost only below 0.3 keV, exposing a model-dependent reservoir of extreme-ultraviolet radiation in six nearby galaxies....
JWST Ruled Out Finding Tiny Moons Around An Exoplanet - That's Great News
3+ day, 23+ hour ago (132+ words) The James Webb Space Telescope (JWST) has opened up many wonders of the cosmos to scientists since it began its science operations a few years ago. But one thing that it hasn’t done is find an “exomoon”. These, as yet…...
Colossal cluster of galaxies discovered from when the universe was only 2.1 billion years old
4+ day, 4+ hour ago (73+ words) Yahoo News UK Scientists have discovered an incomprehensibly massive proto-supercluster - a loosely bound collection of galaxies that will eventually merge into a stable galaxy cluster - from when the universe was only 2.1 billion years old. The international team of astronomers, working…...
COSMOS-z3.1-A: Ancestor of a 5,000-Milky-Way Supercluster
5+ day, 7+ hour ago (207+ words) Astronomers have found COSMOS-z3.1-A, the most distant known ancestor of a galaxy supercluster, with a mass of about 5,000 Milky Ways, using the ODIN survey and the Blanco telescope in Chile. Sources disagree on how old the universe was when…...
