NGC 2389

NGC 2389 is a spiral galaxy in the constellation Gemini about 184 million ly from Earth. It spans roughly 83,000 ly, about 83% of our Milky Way's width. It is receding from us at about 3,783 km/s.

Because its light is 184 million ly from home, you are seeing NGC 2389 as it looked roughly 184 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.
