Astronomers have observed a rare case of a galaxy shapeshifting.
A supermassive black hole that is positively guzzling down dust and gas from its surrounding space looks very different. That material forms a torus and disk that circles the black hole; the extreme gravitational and frictional forces at play cause this disk to blaze with light across the entire electromagnetic spectrum.water swirling down a drain
When the black hole finishes its meal and quietens down again, what remains of those jets can continue to travel through space, spreading out into lobes that continue to emit radio waves. These are known as, and they can be colossal. PBC J2333.9-2343 has such radio lobes, evidence of past black hole activity, spanning a total distance of 3.9 million light-years.
The research team conducted an extremely thorough investigation, collecting observations in radio, infrared, optical, ultraviolet, X-ray, and gamma-ray wavelengths. Then, they compared their observational data against a large database of blazar and non-blazar galaxies. ."They are the relics of past activity, whereas the structures located closer to the nucleus represent younger and active jets."
