Astronomers have discovered an unusual spiral object in the center of our galaxy
A team of astronomers has found an unusual spiral object in the center of Milky Way that resembles a miniature galaxy, but it is not a galaxy within a galaxy. We are talking about a protostar disk, a cloud of gas that feeds and grows the light in it.
The latter is 26,000 light-years away from us and is 32 times more massive than the Sun, and the diameter of the disk itself is 40,000 astronomical units. There are many similar formations in the world, but such a pattern has not been seen by specialists yet. Its distinctiveness lies in the location, stellar mass, and spiral vents that characterize galaxies.
To explain this phenomenon, the scientists used the ALMA telescope, located in the Atacama Desert, with the help of which they discovered that the formation of disc shears is not related to its movement. On the contrary, it was found that their formation was influenced by the interaction with the sun 3 times the massive light near the above-mentioned object.
The picture below first shows the first stage of interaction with light, followed by the result obtained after 4000 and 8000 years (emergence of spiral beams). Finally we see an image of a shape formed at an interval of 12,000 years taken by a telescope.
This is also shown by the simulations of the potential orbits of the object by the researchers. According to one of them, the first “meeting” of disco and luminosity took place exactly 12,000 years ago, which changed the shape of the gas cloud.
The authors’ work was published in the journal Nature Astronomy.
