Light that traveled for more than 8.5 billion years to reach us was the last gasp of a dying star as a black hole swallowed it.
"From the data we have, we can estimate that relativistic jets are launched in only 1 percent of these destructive events, making AT2022cmc an extremely rare occurrence. In fact, the luminous flash from the event is among the brightest ever observed."fast radio bursts
In February, the Zwicky Transient Facility caught just such a flare. Immediately, 20 other telescopes around the world and in space sprang into action, capturing a bucketload of data on the sudden blaze over the days and weeks that followed. Tidal disruption events are extreme; they occur when a star wanders just a little too close to a black hole. The tidal forces in that black hole's gravitational field stretch the star, pulling it so hard that it's torn apart. The star debris then falls onto the black hole.

Astronomers caught a black hole slurping up a star like spaghettiWhen a star ventures a little too close to a black hole, the intense tidal forces suck into it like a giant noodle of star stuff in a cosmic (and much more chaotic) reenactment of that iconic scene in “Lady and the Tramp.” The black hole’s extreme gravitational pull shreds the star into thin strands of material—a process delightfully called “spaghettification.” When these noodle-like strips get sucked into the black hole, they release a powerful bright flare of energy. In September of 2019, the light from such a doomed encounter reached Earth.
