IC 4480

IC 4480 is a barred spiral galaxy in the constellation Boötes about 431 million ly from Earth. It spans roughly 80,000 ly, about 80% of our Milky Way's width. The light reaching us tonight left it about 431 million years ago.

Because its light is 431 million ly from home, you are seeing IC 4480 as it looked roughly 431 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.
