The black hole in the center of our galaxy turns stars into something strange

The Milky Way Galaxy, like so many othersspiral galaxies in the universe, hiding in its center a supermassive black hole called Sagittarius A *. This mysterious object of incredible size constantly attracts stars, dust and other matter to its immediate surroundings, forming a superdense star megalopolis. According to, sometimes stars in the space closest to the black hole have to enter into fierce competition, which sometimes leads to very unpredictable consequences.

At the center of our galaxy is the supermassive black hole Sagittarius A *

Strange objects discovered in the center of our galaxy

In a new study published in a journalNature, astronomers describe six mysterious objects that revolve around the central black hole of our galaxy. According to the authors, the discovered anomalous objects, called G1-G6, look like oblong gas clots several times more massive than the Earth. Despite their small size by cosmic standards, the detected objects behave like small stars, capable of passing dangerously close to the edge of a black hole without being torn to pieces.

What exactly can these fearless space beobjects: gas clots or full stars? According to the authors of the study, strange objects can be both. So, each detected object G can be a pair of binary stars that were broken millions of years ago by the powerful gravity of a black hole. Andrea Gez, a professor of astrophysics at the University of California and co-author of the study, believes that black holes can lead to the merging of binary stars. The background for this hypothesis was the analysis of the orbits of the first two discovered objects G, which followed a strikingly similar orbit around Sagittarius A *.

The gravitational effect of a black hole in the center of our galaxy is able to turn binary stars into objects of a new type

Interpreting gas beams as remnants of a miserableof a dead star damaged by the gravitational impact of a superpowerful black hole located in the neighborhood, some astronomers expected to see the final death of miniature stars as a result of their absorption of Sagittarius A back in 2014. However, much to the scientists' surprise, nothing of the kind happened, and the "non-stars" surprisingly survived within a few hundred astronomical units from the black hole. Stretching and distorting near a black hole, objects G regained their original shape with a gradual removal from it. Such an unusual behavior suggests that something extremely powerful holds the gas clot together - that is, G objects can be full-fledged stars.

To test this hypothesis, the authors of the studyspent several years exploring the center of the galaxy from the W. M. Keck Observatory in Hawaii in search of new G-type objects. The team managed to find four more new clots that met the requirements, revolving around Sgr A *. All of them are products of binary stars crumpled by gravity that formed about 5 million years ago near Sgr A *. Perhaps we will hardly be able to see how these objects look in reality in the foreseeable future, however, the discovery of “crushed” stars suggests that even more potential mysteries for the science of the future may be hidden in the Universe.
