In December 2021, the US-based National Aeronautics Space Agency launched the imaging X-ray polarimetry explorer mission to explore the remnants of supernova explosions, the particle streams emitted by black holes and other cosmic …
Mooley, K.P., Anderson, J. From this, scientists, piecing together evidence from complementary measurements, surmised that the event they had observed was of two neutron stars merging and forming a black hole and, in the process, giving off light. This resolves the earlier fuzziness about what the source was and puts the source clearly as massive neutron stars merging to give …
Scientists have for the first time detected gravitational waves — ripples in the fabric of space-time — produced by the collision of a neutron star and a black hole. The finding confirms that there are systems consisting of a neutron star and a black hole, and will help answer many questions about the cosmos, from star formation to the expansion …
