NASA’s IXPE Challenges Theories on Black Hole Corona and Polarised X-Ray Emissions
NASA’s Imaging X-ray Polarimetry Explorer (IXPE) has made surprising observations in a black hole binary system, detecting a high degree of X-ray polarisation that challenges current models of corona structure and accretion discs. In X-ray binaries, black holes pull matter from nearby stars, forming hot accretion discs and coronas.

How Did Heavy Metals Like Gold, Uranium Form? Research Says Answer Lies in Black Holes
While all heavy metals have formed under extreme conditions inside stars or due to stellar explosions and collision of neutron stars, the question remains: when and why was the material ejected and whether heavy elements can be produced in any other way.

"Study Suggests Formula To Help Probe Black Holes": Union Minister
Union Health Minister Harsh Vardhan on Sunday said that a new study by the scientists from Aryabhatta Research Institute of Observational Sciences has suggested a formula that can help probe black holes by assessing the spectrum emitted from the accretion discs around black holes.
