IC 4608

IC 4608

IC 4608 is a barred spiral galaxy in the constellation Apus about 137 million ly from Earth. It spans roughly 34,000 ly, about 34% of our Milky Way's width. It is receding from us at about 2,928 km/s.

Because its light is 137 million ly from home, you are seeing IC 4608 as it looked roughly 137 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.
