Andromeda Galaxy - Galaxies are collections of billions of stars in space. The Andromeda Galaxy, around 2 million light years away, is the closest one to our own galaxy, the Milky Way. In this picture, the bright core of the galaxy appears surrounded by a faint yellow glow. This glow is the collective light of billions of stars! And because of the distance of these stars, we are seeing their light as it was 2 million years ago! The much smaller satellite galaxy of andromeda, M110, is also visible as a fuzzy yellow ellipse in the far right of the picture.
