IC 4570

IC 4570 is a spiral galaxy in the constellation Corona Borealis about 448 million ly from Earth. It spans roughly 99,000 ly, about the width of our Milky Way. It is receding from us at about 9,637 km/s.

Because its light is 448 million ly from home, you are seeing IC 4570 as it looked roughly 448 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.
