NGC 5801

NGC 5801 is a barred spiral galaxy in the constellation Libra about 381 million ly from Earth. It spans roughly 79,000 ly, about 79% of our Milky Way's width. The light reaching us tonight left it about 381 million years ago.

Because its light is 381 million ly from home, you are seeing NGC 5801 as it looked roughly 381 million years ago. The photons left before that much of history had passed, and are only now reaching us. This distance is estimated from the galaxy's redshift, so the lookback time is approximate.
