NGC 3204

NGC 3204 is a barred spiral galaxy in the constellation Leo about 231 million ly from Earth. It spans roughly 84,000 ly, about 84% of our Milky Way's width. The light reaching us tonight left it about 231 million years ago.

Because its light is 231 million ly from home, you are seeing NGC 3204 as it looked roughly 231 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.
