Astronomers have discovered a group of stars fugitives

U.S. scientists have discovered receding at high speed from the host galaxy globular cluster . His study authors published in the Astrophysical Journal Letters, briefly with him can be found at Sci-News.com.

Astronomers first discovered a massive globular cluster HVGC- 1 , moving away from home galaxy Messier 87 at a speed of about 900 kilometers kilometers per second. To do this, the researchers analyzed the spectral and photometric data of stars, which determined what clusters are scattered , and what - ball , and measured their speed. To get their results , astronomers studied every globular cluster separately.


Globular clusters contain the earliest ( and old ) stars have appeared in the galaxy. These stars are related to the gravitational field of spherical ordered associations, rotating as a whole around the galactic core . In elliptical galaxy Messier 87 has them to a few thousand , in the Milky Way - about 150 clusters. Compared with spherical stars in open clusters are weakly bound by gravitational forces , younger and located in the galactic disk . Role in the evolution of globular clusters of galaxies is not fully understood .

Astronomers believe such behavior HVGC- one manifestation of what Messier 87 formed in the collision of two galaxies, so it may be in its center two supermassive black holes . Object HVGC- 1 - first discovered globular cluster , moving away from the galactic center with a high speed.
