We Finally Measured How Big the Andromeda Galaxy Really Is...

Two point five million years of light travel away, a monster is growing larger. Scientists just measured something impossible. The Andromeda galaxy is not the size we thought. It is six times wider than the full Moon in your sky right now, but you cannot see it. Its invisible halo stretches halfway to Earth, already touching our galaxy. One trillion stars spin inside a disk two hundred twenty thousand light years wide, surrounded by a gas cloud extending two million light years in some directions. The collision everyone predicted might not happen at all, or it might tear both galaxies apart. If you enjoy learning about the cosmos, consider subscribing. We are about to explore the largest structure you cannot see. Prepare yourselves. We begin.
