NGC 3620

NGC 3620 is a barred spiral galaxy in the constellation Chamaeleon about 83 million ly from Earth. It spans roughly 76,000 ly, about 76% of our Milky Way's width. The light reaching us tonight left it about 83 million years ago.

Because its light is 83 million ly from home, you are seeing NGC 3620 as it looked roughly 83 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.
