NGC 3175

NGC 3175 is a spiral galaxy in the constellation Antlia about 50 million ly from Earth. It spans roughly 77,000 ly, about 77% of our Milky Way's width. It is receding from us at about 1,095 km/s.

Because its light is 50 million ly from home, you are seeing NGC 3175 as it looked roughly 50 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.
