NGC 3803

NGC 3803 is a barred spiral galaxy in the constellation Leo about 167 million ly from Earth. It spans roughly 30,000 ly, about 30% of our Milky Way's width. The light reaching us tonight left it about 167 million years ago.

Because its light is 167 million ly from home, you are seeing NGC 3803 as it looked roughly 167 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.
