IC 4189

IC 4189 is a spiral galaxy in the constellation Canes Venatici about 224 million ly from Earth. It spans roughly 81,000 ly, about 81% of our Milky Way's width. It is receding from us at about 4,810 km/s.

Because its light is 224 million ly from home, you are seeing IC 4189 as it looked roughly 224 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.
