The scientists reported that the VLA radio telescope was probably found in the Cygnus A galaxy, which is the first radio galaxy in the history of observations, the second large Black Hole. The journal Astrophysical Journal write that the object was hidden from astronomers for more than 20 years.
Rick Perley of the National Radio Astronomy Observatory in Socorro recalls that in 1980 the VLA was already making photographs of this galaxy, which then demonstrated the possibilities of radio astronomy. Then, when the telescope was updated in 2012, astronomers decided to take new pictures of Cygnus A and were surprised to find a new object in the center of the galaxy that had not been seen in the images before. Swan A is a galaxy with a large cluster of stars. It is impossible to see it in the optical range because of the long distance, but it can be seen by radio emission. Every second Galaxy Swan A allocates as much energy as would allocate 260 billion of our Suns. The source of energy are powerful quasars, active Black Holes in the centers of radio galaxies, which with a high speed throw some of the captured matter in the form of beams of hot matter into the intergalactic space. Such bundles are called scientific jets, they brightly shine in the radio range. On the shots they are visible, as long, bright "tails". VLA, observing Swan A in November 2016, managed to display on the snakes of the nucleus Cygnus A not one, but two pairs of such tails. One pair belonged to the first Black Hole, discovered several decades ago, but the second one is already "new", located 1,500 light years from the first. The study of Cygnus A with the help of other telescopes, including those capable of seeing the galaxy in the other part of the electromagnetic spectrum, confirmed the existence of a massive object. There are two versions that have been discovered. This is either a flash from the supernova remnants, or a powerful Black Hole that appeared not long ago and began to absorb the space around itself. Both theories are viable and applicable to the discovered object. However, Rick Perlie believes that we are talking about the Black Hole, since such a powerful and long gamma-ray bursts and radio waves from supernovae are extremely rare.
