"Alien Galaxy's Mysterious Star Found in the Heart of the Milky Way"

Astronomers have determined that a star named S0-6, located at the center of the Milky Way and orbiting a supermassive black hole, has an extragalactic origin. Using the Subaru Telescope, researchers analyzed the star's velocity, trajectory, and chemical composition, finding that it is low in heavy elements and most similar to stars in dwarf galaxies orbiting the Milky Way. This discovery suggests that remnants of these galaxies could have made their way towards the galactic center, providing observational evidence of the Milky Way's history of devouring other galaxies. Further research is needed to confirm these findings and unravel the mysteries of stars near supermassive black holes.

Young stars lead solitary lives at Milky Way's center.

A 10-year survey using the W. M. Keck Observatory has found that young, massive main-sequence stars living closest to the supermassive black hole at the center of the Milky Way have no stellar companions. The S-stars, which are only about six million years old, are all single, which is surprising given that stars at this age and mass usually spend their childhood years paired with a twin in a binary system. The researchers suggest that the black hole's powerful influence causes binary star systems to either merge or become disrupted, where a companion star gets kicked out from the region.
