The distant object suddenly started feeding after a prolonged silence.
have jet- and wind-emitting supermassive black holes at their cores. An ultraviolet spectrum of the object suggested to the research team that material was pushed outwards by some energetic outburst. A black hole suddenly deciding to feed could effectively “switch on” a galactic nucleus, and may be the situation at play in J221951.Tidal disruption events occur when a star passes close—too close—to a black hole, causing it to yield at least some of its material to the abyss.
“We will need to continue to monitor J221951 over the next few months to years to capture its late-time behavior,” Oates added.Black holes only have a vacant demeanor if you peer into their lightless shadows. Observing their effects on surrounding matter reveals that black holes are some of the most dynamic objects in the universe. Just this week, astronomers using the Webb Space Telescope announced the, which dates back to around 570 million years after the Big Bang.
Whether it was an unfortunate star or a hungry, hungry hole—or both!—in J221951, the truth may help astronomers understand black hole behavior, and the sort of conditions that might cause such a behemoth to suddenly decide to “eat.”The cosmos has plenty of many mysteries strewn across space and time. With just a few telescopes and some more observations, astronomers might clarify what went down in that ancient galaxy some 10 billion light-years away.
