NGC 3125

NGC 3125 is an elliptical galaxy in the constellation Antlia about 52 million ly from Earth. It spans roughly 18,000 ly, about 18% of our Milky Way's width. It is receding from us at about 1,080 km/s.

Because its light is 52 million ly from home, you are seeing NGC 3125 as it looked roughly 52 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.
