Astronomers in the United States have found a new class of unusual celestial bodies, at the center of our galaxy, the Milky Way. The University of California researchers team said that these objects look like gas, but their behavior is similar to that of stars. The team had announced in the current issue of the British “Nature” magazine, the discovery of four heavenly bodies that were not known so far, bringing the number of bodies of this type to six.

The team, which works under the supervision of the scientist Andrea Gies, found in 2005 the first such object, and they called it G1, and it rotates in the orbit of a giant black hole in the center of the galaxy, and comes very close to it, from time to time. Meanwhile, scientists from the German Max Planck Institute for Non-Earth Physics in 2012 managed to find another body and called it the G2 code, which passed in 2014 near the center of the black hole.

Jez mentioned that when G2 once again approached the black hole he had managed to leave a truly rare footprint, adding: “We had seen this before, but it did not seem very strange, until it approached the black hole and expanded.”

The scientist pointed out that this object loses a large part of its gas during this time, and turns from a non-striking one to an extended and deformed one when it approaches the big black hole. The Geez team has so far found four other bodies in the center of the huge black hole at the center of the Milky Way, they called them codes from G3 to G6, “We now have a grouping of G bodies,” researcher Anna Ciorlo, a Geez fellow, said, adding : That is, it is not a matter of revealing the truth of a unique event such as G2.

Jeez suggests that these six bodies are fused together, or are double stars that still fuse together. Although the G2 had lost its gaseous casing as it approached the black hole, it did not lose the thick dust casing inside the gas, which means that there is something that maintains its consistency and prevents it from melting, and enables it to survive after meeting the black hole, according to Ciorlo, adding : This is evidence of the presence of asteroid inside the G2.

At the same time, according to researchers, this group of celestial bodies is likely to have an impact on the activity of the center of the black hole, by feeding it with gas every time it approaches it, in which this explains Mark Morris, one of the study participants: “When this happens it becomes The hole is able to produce massive fiery forms, because the heat that the black hole swallows rises strongly and emits a lot of radiation, before it disappears behind the event horizon.
