IC 4474

IC 4474 is a barred spiral galaxy in the constellation Boötes about 437 million ly from Earth. It spans roughly 83,000 ly, about 83% of our Milky Way's width. The light reaching us tonight left it about 437 million years ago.

Because its light is 437 million ly from home, you are seeing IC 4474 as it looked roughly 437 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.
