Astronomers find over 200 most distant stars in Milky Way


Astronomers have discovered over 200 distant variable stars called RR Lyrae stars in the Milky Way’s halo. The most distant of these stars are over a million light-years away from Earth, almost half the distance to our neighbouring galaxy, Andromeda, located around 2.5 million light-years away. These observations could help confirm the theoretical estimates of the halo’s size.
