Delhi: Scientists have discovered a cluster of stars in the farthest reaches of the Milky Way Galaxy in the Solar System. Within our own galaxy is a cluster of stars more distant from Earth than about halfway to a neighboring galaxy. The researchers said these 208 stars reside in the farthest reaches of the Milky Way’s mantle, a globular stellar cloud surrounded by a mysterious invisible substance called dark matter known only through its gravitational influence.

The farthest of them is 1.08 million light-years from Earth (a light-year is the distance that light travels in one year, 5.9 trillion miles). These stars, seen using the Canada France Hawaii Telescope on Mount Mauna Kea in Hawaii, are part of a class of stars called RR Lyrae that are relatively low-mass and typically contain small amounts of elements heavier than hydrogen and helium. The most distant mass appears to be about 70 percent of the mass of our Sun. No other star in the Milky Way has been measured to be more distant than these.

the galaxy gravitationally merged with its own Milky Way
Yuting Feng, a NASA astronomy doctoral student at the University of California, Santa Cruz, who led the study, presented it this week at an American Astronomical Society meeting in Seattle. Feng said that larger galaxies may have gravitationally merged smaller galaxies into their own galaxy, but these stars are left at such great distances as the debris of the merger event over time through such catastrophes. The Milky Way has evolved.
