Finally, we know the answer, and they are strange objects at the center of our galaxy

For more than 20 years, we have been close to the center of our galaxy, near the supermassive black hole Sgr A* that inhabits the heart of the Milky Way, They discovered something very strange that scientists always thought was just a big cloud of gas and dust.

A new study published in the journal Astrophysical Journal However, it has shown that this is something completely different. The portal drew attention to the topic Phys.

An object that gives scientists a headache

Scientists have discovered two huge clouds, named G1 and G2. When G2 was at perihelion (the place that was closest to the black hole) in 2014, it started behaving very differently than we expected.

It did not rupture, but rather extended from a compressed body into a strange elongated shape and then returned to its original shape.

These results led to the assumption that what we call the black hole Sgr A* is in fact A strange type of dark matter known as “darkinos”.

Now, in a new study, scientists have found that the G2 object is actually three stars.

As mentioned, as object G2 approached a black hole, it was expected that there would be a huge “fireworks display” in which Sgr A* would tear up and devour the object, which didn’t happen to everyone’s surprise.

In addition, this building was surrounded by other properties. Studies have shown that the temperature of G2 is approximately two times higher than that of ambient clouds or dust sources. This was explained by the fact that there seemed to be a very large number of stars in the center of our galaxy that could have warmed this cloud.

Object G2 holds a secret

But then the question arose as to why only G2 was heated to this temperature, and not other sources of dust in the center of the galaxy. In short and simply, the longer it was observed by scientists, the more mysterious the object became, and it became clear that it must be more than just a cloud of dust and gas.

Recent observations by G2 through the Very Large Telescope (VLT) showed that this is not really an ordinary cloud of dust, but an object consisting of 3 advanced stars that began to form less than a million light-years ago. According to Florian Bisker, who was involved in the research, we’ve never seen younger stars around the galactic center.

Now, however, the question arises as to where these young stars come from, because the vicinity of a supermassive black hole is not exactly the ideal environment for their formation.
