Scientists Have Detected the First Stars
See that fuzzy blob on the sky? The one just left of the Milky Way center in the constellation of Andromeda. That’s M31 – the Andromeda galaxy. It’s two and a half million light years away and host to a trillion stars. It has a beautiful spiral structure spanning its gently rotating disk 220 thousand light years in diameter, and a central bulge that hides a giant black hole that contains the mass of well over a hundred million Suns. Andromeda is also racing towards our galaxy at 110 km/s.
