IC 1220

IC 1220 is an elliptical galaxy in the constellation Hercules about 462 million ly from Earth. It spans roughly 170,000 ly, about 1.7 times the width of our Milky Way. The light reaching us tonight left it about 462 million years ago.

Because its light is 462 million ly from home, you are seeing IC 1220 as it looked roughly 462 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.
