Andromeda Galaxy
Our giant neighbour galaxy — the farthest thing you can see with your eyes.
From a dark site it looks like a faint elongated smudge. That smudge is about a trillion stars, 2.5 million light-years away.
Andromeda and our Milky Way are heading towards each other and will merge in roughly 4–5 billion years.
