IC 4729

IC 4729 is a spiral galaxy in the constellation Pavo about 208 million ly from Earth. It spans roughly 79,000 ly, about 79% of our Milky Way's width. It is receding from us at about 4,419 km/s.

Because its light is 208 million ly from home, you are seeing IC 4729 as it looked roughly 208 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.
