Astronomers have discovered the farthest group of stars from Earth that has been observed so far within the boundaries of the Milky Way galaxy, in the stellar halo on its outer borders.
Reuters quoted researchers who monitored the stars on Mauna Kea in Hawaii as saying: These 208 stars reside at a distance of 1.08 million light-years from Earth in the outer halo regions, which is a spherical cloud of stars dominated by the mysterious, invisible matter that Scientists call it dark matter, the existence of which is known only through the influence of its gravity.
The researchers pointed out that these stars belong to the class of stars called (RR Laray), which have a relatively low mass and are characterized by a lack of elements heavier than hydrogen and helium, with a mass of about 70 percent of the mass of the sun.
Yuting Feng, a researcher in astronomy at the University of California, explained that the explanation for the origin of these distant stars is that they were most likely born in the halos of dwarf galaxies and star clusters that attracted them or, in a more clear expression, were swallowed by the Milky Way.
