    Astronomers discover S0-2 star is Single and Ready for Big Einstein Test

    No companion found for famous young bright star orbiting Milky Way’s supermassive black hole. Astronomers have the “all-clear” for an exciting test of Einstein’s Theory of General Relativity, thanks to a new discovery about S0-2’s star status. Up until now, it was thought that S0-2 may be a binary, a system where two stars circle around each other. Having such a partner would have complicated the upcoming gravity test.

    A team of astronomers led by a UCLA scientist from Hawaii has found that S0-2 does not have a significant ...

    Scientists Identify a Black Hole Choking on Stardust

    March 17, 2017, Categories  Astronomy/Space

    In this artist's rendering, a thick accretion disk has formed around a supermassive black hole following the tidal disruption of a star that wandered too close. Stellar debris has fallen toward the black hole and collected into a thick chaotic disk of hot gas. Flashes of X-ray light near the center of the disk result in light echoes that allow astronomers to map the structure of the funnel-like flow, revealing for the first time strong gravity effects around a normally quiescent black hole.

    An international team of astronomers, including Lancaster’s David Sobral, has discovered a cosmic one-two punch never seen before. 2 of the most powerful phenomena in the Universe – a supermassive black hole and the collision of giant galaxy clusters – have combined to create a stupendous cosmic particle accelerator. By combining data from some of the best X-ray, optical and radio telescopes in the world, researchers have found out what happens when matter ejected by a giant black hole is swept up in the merger of two enormous galaxy clusters.

    This cosmic double whammy is found in a pair of colliding galaxy clusters called Abell 3411 and Abell 3412 located about 2 billion light years from Earth...
