The new simulations show that this debris forms an asymmetric bubble around the black hole, reprocessing the energy and producing the observed light curves with lower temperatures, fainter ...

In a nutshell Stellar flares emit 3-12 times more far-ultraviolet radiation than previously thought, based on analysis of 182 ...

By taking photos of the stellar remnant using a range of tools and filters on the James Webb Space Telescope (JWST), astronomers are getting their clearest look ever at Cassiopeia A. Astronomer and ...

Stellar light show predicted for next year as black hole swallows star By Michael Irving. August 26, 2024 ... Almost two years later, the X-ray and UV light flared back up.

Planets orbiting red dwarf stars may have a harder time hanging on to the conditions needed for life to arise and survive than previously thought, data from NASA's dead space telescope GALEX reveals.

A groundbreaking study has revealed that red dwarf stars can produce stellar flares that carry far-ultraviolet (far-UV) radiation levels much higher than previously believed.
