The andromeda galaxy has added new stars to its firmament. And we do not say this figuratively or as a way of metaphorizing some concept or information. The truth is that a group of scientists have detected the greatest migration of stars within the field of astronomy Until now.
Using the Dark Matter Spectroscopic Instrument, or DESI, the group of experts found evidence of a massive movement of stars from one galaxy to another clearly.
This discovery, or rather record, highlights one of the most discussed or rumored theories among the scientific community: galaxies are “built” from smaller galaxies.
star migration
Arjun Dey, the scientist in charge of the project, stated that the recent star migration recorded by DESI supports the postulation that the andromeda galaxy it merged with another large galaxy more than two billion years ago.
It is known, thanks to DESI, that about 7,500 stars migrated massively towards Andromeda making it one of the largest galaxies recorded so far.
“Never before have we seen a massive stellar movement so clearly, and we also did not know structures resulting from such a phenomenon,” said Sergei Kosopov, co-author of the study.
Although up to now the exact galaxy of origin or where the images come from is not known. stars that joined Andromeda, due to the composition of the stars, rich in metals, the group of scientists determined that it is a galaxy with a “long history of star formation that could involve not one, but many more galaxies.” ”.
As of now, no details have been released around this research as scientists continue to analyze the data captured by DESI. In the same way, it is expected that during the following weeks, the galaxy of origin can be determined as well as the new formation of Andromeda after the addition of the new stars.
