IC 3528

IC 3528 is a spiral galaxy in the constellation Coma Berenices about 640 million ly from Earth. It spans roughly 61,000 ly, about 61% of our Milky Way's width. It is receding from us at about 13,764 km/s.

Because its light is 640 million ly from home, you are seeing IC 3528 as it looked roughly 640 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.
