A normal star passes near a supermassive black hole in the center of a galaxy. This sequence of artist's illustrations shows how a black hole can devour a bypassing star. Only a few of these so called “massive fails” ( yes, that’s what they’re calling them) have been spotted, so astronomers are cautious about the results. Astronomers using NASA's Hubble Space Telescope have recorded a star's final moments in detail as it gets gobbled up by a black hole. Rather than exploding, the gas collapses directly into the core of the star. This can happen when the core collapse of the star is especially massive. The Event Horizon Telescope (EHT) a planet-scale array of eight ground-based radio telescopes forged through international collaboration was designed to capture images of a black hole. Neutron star or black hole Depending on the mass at the start of its life, a supernova will leave behind either a neutron star or a black hole. What is a Black Hole Library of Congress When a particularly large star nears the end of its life, it often becomes a black hole. The supermassive black hole imaged by the EHT is located in the center of the elliptical galaxy M87, located about 55 million light years from Earth.
While some supernova events are explosive and leave clouds of debris for thousands of years (aka nebula) like SN 1054, the star in question seems to have begun to explode and then had all its gas sucked right back into the black hole at the center. An exploding supernova throws hot gas into space. And now, Hubble seems to have seen a supernova blink out - suggesting it captured the moment when a black hole took over. What’s left is mostly neutron stars or black holes. When a massive star expends its fuel, its core collapses into a dense object and sends the rest of its gas outward in an event called a supernova.
