IC 4515
IC 4515 is a spiral galaxy in the constellation Boötes about 441 million ly from Earth. It spans roughly 130,000 ly, about the width of our Milky Way. The light reaching us tonight left it about 441 million years ago.

Because its light is 441 million ly from home, you are seeing IC 4515 as it looked roughly 441 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.
