Periodically, these gravitational behemoths will devoir stars and other objects in their vicinity, releasing tremendous amounts of light and radiation.
In October 2018, astronomers witnessed one such event when observing a black hole in a galaxy located 665 million light-years from Earth....another team from the Harvard & Smithsonian Center for Astrophysics noticed something unprecedented when they examined the same black hole three years later. As they explained in a recent study, the black hole was shining very brightly because it was ejecting...leftover material from the star at half the speed of light.
[T]he team observed the outburst while revisiting data on tidal disruption events (TDEs) that took place over the last few years. These occur when stars pass too close to black holes and are pulled apart during multiple passes, a process known as “spaghettification” because of how the stars are ripped into strands.
To their surprise, they noticed that the black hole had mysteriously become reanimated.
The team concluded that this resulted from the black hole ejecting residual material from the star at relativistic speeds (a fraction of the speed of light). This is the first time astronomers have ever observed such a phenomenon, and the team is unsure why the outflow was delayed by several years.
In some cases, spaghettified material will be thrown back into space, which astronomers liken to black holes being “messy eaters.” However, the outflow emissions normally develop quickly after a TDE occurs and not years later. In short, said Cendes, it’s as if this black hole began abruptly burping out a bunch of stellar material it ate years ago. What’s more, these “burps” were extremely energetic, with ejected material reaching speeds of up to 50% the speed of light – about five times what astronomers have observed with other TDEs

There’s always something new to learn
When you feast upon a star...
There’s Hawking radiation...Supposedly...
Maybe this is hawked radiation... Could name it lunga #1...
The more we Lear, the less we know…
The idea of being able to “see” something 665 million light years away is mind boggling enough without even considering a black hole with indigestion...smh
Spaghettification by messy eaters... sounds like a coyote kill.
