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.
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.
NASA's Chandra X-ray Observatory has discovered a new type of compact binary star system unlike anything previously observed. These objects were found to emit very low-energy X-rays while also radiating a large amount of ultraviolet light.
The Chandra X-ray Telescope has discovered a new class of compact binary stars that emit intense ultraviolet light while also emitting low-energy X-rays; these mysterious objects are said to have the potential to solve two major mysteries of astrophysics.
NASA's Chandra telescope identified 84 candidates in six galaxies that emit very low-energy X-rays, but extraordinary amounts of ultraviolet light. The finding could provide clues about the ionization of the interstellar medium and about possible progenitors of Ia-type supernovas.
