Good morning, Rallypoint. Today's Astronomy Picture of the Day (APOD) is titled "A Black Hole Disrupts a Passing Star." First things first: this image is an artist's interpretation. But it seems well based on evidence. A tidal disruption event (also known as a tidal disruption flare) occurs when a star approaches sufficiently close to a supermassive black hole and is pulled apart by the black hole's tidal force (e.g. gravity). A portion of the star's mass is captured into an accretion disk around the black hole, resulting in a temporary flare of electromagnetic radiation as matter in the disk is consumed by the black hole. This flare is detectable by instruments such as NASA's Transiting Exoplanet Survey Satellite (TESS), the Wide-field Infrared Survey Explorer (WISE), and Chandra X-ray space telescope. TESS recently observed a tidal disruption event in January 2019 that was located in a galaxy found in the Southern constellation Volans, around 375 million light years away.

Just a bit faster than ludicrous speed

Good Tuesday morning my friend Maj William W. 'Bill' Price and thank you for posting the NASA Astronomy artistic impression of the Day (AAIOD) for march 24, 2020 entitled "A Black Hole Disrupts a Passing Star."

"Explanation: What happens to a star that goes near a black hole? If the star directly impacts a massive black hole, then the star falls in completely -- and everything vanishes. More likely, though, the star goes close enough to have the black hole's gravity pull away the outer layers of the star, or disrupt the star. Then most of the star's gas does not fall into the black hole. These stellar tidal disruption events can be as bright as a supernova, and an increasing amount of them are being discovered by automated sky surveys. In the featured artist's illustration, a star has just passed a massive black hole and sheds gas that continues to orbit. The inner edge of a disk of gas and dust surrounding the black hole is heated by the disruption event and may glow long after the star is gone."

The disruption of the A Black Hole Disrupts a Passing Star." brought to mind ludicrous speed :-)
