  Mysterious star SO-6 traveled across the Milky Way. 

"A new study reveals that the star S0-6, located near the Milky Way’s central black hole, originated from an external galaxy, reshaping our understanding of star migration and formation in our galaxy."(ScitechDaily.com/Across Time and Space: Mysterious Star’s Epic Journey to Heart of Milky Way)

A star near the supermassive black hole at the center of the Milky Way Galaxy originated outside of the Galaxy according to a new study. This is the first time a star of extragalactic origin has been found in the vicinity of the supermassive black hole".

"Researchers have discovered an extragalactic star, S0-6, near the Milky Way’s central supermassive black hole. The star’s unique composition and 10 billion-year journey from a small, now-absorbed galaxy challenge our understanding of the galactic center’s star population and formation.

"The central region of the Milky Way galaxy as captured by the Subaru Telescope. The image shows many stars in a field of view about 0.4 light-years across. The star S0-6 (blue circle), the subject of this study, is located about 0.04 light-years from the supermassive black hole Sagittarius A* (Sgr A*, green circle).

Star SO-6 near Sagittarius A is born in some small galaxy near Milky Way. Then Milky Way's gravity destroyed that galaxy and pulled SO-6 to a trajectory across the Milky Way to trajectory that orbits Sagittarius A* the supermassive black hole in the middle of our galaxy. 

And why SO-6 is the only star that has made this kind of journey? Where are all other stars from the dwarf galaxy that is the origin of the SO-6? Is there some special thing that affects only SO-6? If the particle's spin in SO-6 is very high, that can push Milky Way's plasma away. Or make some other unusual interaction between Milky Way stars, gravitational fields, and plasma. 

How SO-6 could travel across the Milky Way without contact with neutron stars, white dwarfs, or black holes? That interaction would destroy the SO-6 immediately. If the spin of SO-6 is so high, it is possible, that plasma interaction with SO-6 and other stars is different. But the origin of that star in some other galaxy causes questions about the material in other galaxies. 

Even if the spectroscope sees SO-6 similar to other stars there could be differences between it and Milky Way's stars atoms and subatomic particles. Can the energy level between SO-6 and other stars be somehow different? Can the size of fermions be different in SO-6 and other stars around it? 

SO-6 is interesting. And that star can tell about star's life in those distant galaxies. So research continues.
