NGC 2291

NGC 2291 is a lenticular galaxy in the constellation Gemini about 241 million ly from Earth. It spans roughly 65,000 ly, about 65% of our Milky Way's width. The light reaching us tonight left it about 241 million years ago.

Because its light is 241 million ly from home, you are seeing NGC 2291 as it looked roughly 241 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.
