One of the most mysterious objects in the Universe — black holes, hidden in an incredible amount of secrets. Scientists around the world scratching their heads over such issues, how and why supermassive black holes exist at the centers of galaxies that lies behind the event horizon, and can black holes be portals to other Universes. However, today, scientists know about these space objects more than ever in history. Recently we wrote about the fact that NASA has provided the world with a visualization of a black hole. Today we will tell you about a new study by astronomers. Scientists have discovered something surprising — three black holes can collide with each other.
Why this anomaly?
In the vastness of the infinite, expanding Universe all in charge of the force of gravity. Countless number of different celestial objects collide among themselves, be they galaxies, stars or planets. Recently, scientists have discovered three supermassive black holes that reside at the centres of the three galaxies. This phenomenon makes that the three galaxies that are billions of light-years from our planet, are facing each other. However, there is another strange thing — it turned out that these supermassive objects that glow in x-rays.

In 2017, scientists announced to the world about the discovery of gravitational waves predicted by relativity theory of albert Einstein. Gravitational waves have reached our planet, originating in the collision of two supermassive black holes. Thus, the researchers first obtained data on the fusion of these space monsters. However, according to scientists, Observatory LIGO or VIRGO will not be able to detect gravitational waves that arise as a result of collision of three galaxies, due to their low frequency. But about all under the order.
As scientists have discovered an anomaly?
It all started with the discovery of merging galaxies in optical light telescope Sloan Digital Sky Survey (SDSS) in new Mexico. The researchers then examined data collected by the spacecraft NASA’s Wide-field Infrared Survey Explorer (WISE). Scientists say that WISE has detected infrared radiation during the merger of galaxies. Further observations in x-ray and optical light confirmed the assumptions of astronomers that in the center of each of the three galaxies is a black hole.

Subsequently x-ray Observatory NASA’s Chandra has detected x-ray sources near each of the centers of the merging galaxies. This suggests that near the center of galaxies consumed a lot of gas and dust, and this is a sign of the presence of a black hole. According to experts, every telescope has provided unique data, which confirmed that before them is a truly unusual discovery of three black holes exist in the center of colliding galaxies.
According to the researchers, the discovered collision of such massive objects is different from the collision of two black holes. The fact that each of the three black holes is the core of the galaxy, which actively absorbs material. Due to the fact that in the absorption process, the material emits brilliant light, scientists were able to detect this unusual system. Experts note that these objects are quite difficult to detect as they are surrounded by large amounts of dust and gas, and that makes it hard to search.
Black holes help galaxies evolve
It is no secret that all space objects has its own life cycle. So astronomers argue that the abnormal system is discovered during a recent study, evidence of evolution of galaxies. The key to understanding such processes is a black hole. Computer simulations showed that about 16% of the galaxies that collide with each other and which are rotating supermassive black holeswill interact with the third supermassive black hole. According to researchers, a third black hole contributes to a more rapid merger process of galaxies.
Also, this study can shed light on “the mystery of the last parsec” — it tells us that in the process of merging two galaxies, the black holes at their centers face each other, and flies over the barrier, thus forming a double system at a distance of several parsecs. Thus, the third black hole can finally be combined.
