    Hubble pinpoints roaming massive black hole

    May 9, 2025, Categories  Astronomy/Space

    Six-panel illustration marked "Artist's Concept." The upper left panel shows the silhouette of supermassive black hole that is adrift inside a galaxy. The middle upper panel shows a yellow star drifting near the black hole. The three following panels show the star being shredded in bright white concentric streamers followed by a white explosion. the bottom right panel is an external view of the galaxy showing a bright white star-like object that is the site if the explosion as viewed in X-rays and visible light.
    This six-panel illustration of a tidal disruption event around a supermassive black hole shows the following: 1) A supermassive black hole is adrift inside a galaxy, its presence only detectable by gravitational lensing; 2) A wayward star gets swept up in the black hole’s intense gravitational pull; 3) The star is stretched or “spaghettified” by gravitational tidal effects; 4) The star’s remnants form a disk around the black hole; 5) There is a period of black hole accretion, pouring out radiation across the electromagnetic spectrum, from X-rays to radio wavelengths; and 6) The host galaxy, seen from afar, contains a bright flash of energy that is offset from the galaxy’s nucleus, where an even more massive black hole dwells.
