NGC 2388

NGC 2388 is a barred spiral galaxy in the constellation Gemini about 182 million ly from Earth. It spans roughly 46,000 ly, about 46% of our Milky Way's width. The light reaching us tonight left it about 182 million years ago.

Because its light is 182 million ly from home, you are seeing NGC 2388 as it looked roughly 182 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.
