Researchers studying supermassive black holes called SDSS J1354 + 1327 at a distance of 800 million light-years from Earth capture a rare phenomenon.
The black hole is seen burping by issuing a bright light that moves like a shock wave after swallowing hot gas.
In fact, this phenomenon has been understood by researchers. Although supermassive black holes are usually in the midst of silent galaxies, sometimes they can be triggered to eat when there is a gas approaching and releasing high-energy particles.
Unfortunately, this phenomenon is quite rare to see, and a team led by researchers from the University of Colorado Boulder was fortunate to see it through the Hubble telescope, Sinar X Chandra Observatory, and other observatories in Hawaii and New Mexico, USA.
In addition to the incident, the researchers also found the remains of the previous burp that occurred about 100,000 years before being witnessed this time.
Study leader Assistant Professor Julie Comerford of CU Boulder told Space.com that black holes are greedy eaters, but they also do not have a good eating procedure.
"We already have many examples of black holes that burp once, but this is the first time a supermassive black hole burps twice that we observed in the galaxy," he continued.
This discovery has been presented by researchers in The Astrophysical Journal.
