A star hurled over our galaxy Probably a tremendous speed was ejected through a kind of black hole from its birth galaxy that has never been seen in our galaxy.
Researchers from the Keck Telescope believe that the star PG 1610 + 062 was thrown across the galaxy by a moderately heavy black (MMBH).
Data from the Keck Observatory showed that PG1610 + 062 is indeed a surprisingly young, massive star that is ten times more massive and ejected from the Galactic disk at nearly the escape velocity from the Milky Way galaxy.
I think there is only one probable culprit – a black hole in the middle of the mass.
It has been predicted that such objects exist in young star clusters in the spiral arms of the Milky Way, but no one has yet been discovered.

& nb ;, PG1610 + 062 can provide evidence that MMBHs might indeed exist in our galaxy. says the main author Andreas Irrgang of the Friedrich-Alexander-University Erlangen-Nürnberg.
The race is progressing to actually find her. "
The team needed spectral data from the star, but its distance and position in the sky made the echelette spectrograph and imager (ESI) of the WM Keck Observatory the only tool for this task.
In the northern hemisphere, only the combination of Keck Observatory and ESI gave us what we needed. Keck's collection enabled us to collect enough photons for our object, and ESI has just the right resolution high enough to resolve all the spectral features.
