Astronomers detect an extremely red supermassive black hole in the early universe growing in the shadows
Analyzing images from the James Webb Space Telescope (JWST), a group of astronomers led by Dr. Lukas Furtak and Prof. Adi Zitrin from Ben-Gurion University of the Negev has detected an extremely red, gravitationally lensed supermassive black hole in.....»»
Daily Telescope: Finally, we’ve found the core of a famous supernova
In the astronomy community, SN 1987A has somewhat legendary status. Enlarge / Webb has observed the best evidence yet for emission from a neutron star at the site of Supernova 1987A. (credit: NASA, ESA, CSA, STScI, et. al.).....»»
Further study of bright gamma-ray burst GRB 230307A shows it was caused by neutron stars merging
An international team of astronomers and astrophysicists has found evidence that the bright gamma-ray burst GRB 230307A observed last year was caused by two neutron stars merging, not from a collapsing massive star. In their study, published in the j.....»»
