IC 4964

IC 4964 is a spiral galaxy in the constellation Pavo about 148 million ly from Earth. It spans roughly 68,000 ly, about 68% of our Milky Way's width. It is receding from us at about 3,147 km/s.

Because its light is 148 million ly from home, you are seeing IC 4964 as it looked roughly 148 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.
