A very large telescope removed a galaxy with two supermassive black holes

A very large European Space Observatory telescope took a picture of the NGC 7727 galaxy. This giant was born as a result of the merger of two other galaxies, which took place about a billion years ago, and as a result two supermassive black holes at the center of NGC 7727.

The impact of galaxies is not like a meeting of two solid bodies. Most of the space of these systems is empty, filled only with gas molecules. So, in a collision, the two galaxies are as if they were spinning in a common dance, while the tide forces created by gravity change the shape of the primary structures.

The tails of stars, gas, and dust twist around the galaxy, forming a new system. It usually has an unusual and asymmetrical shape, such as that seen in the new picture of NGC 7727.

This galaxy is located at a distance of 89 million light years from the Earth in the constellation Water, and in addition to its unusual shape, it attracts researchers with two massive centres remaining from the original objects. Each core consists of a dense group of stars with a supermassive black hole in the center.

Researchers note that the gravity centers at NGC 7727 are the closest pair of black holes ever discovered, with a distance of only 1,600 light years, and in just 250 million years they will form one even larger black hole.
