NGC 3459

NGC 3459 is a barred spiral galaxy in the constellation Crater about 198 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 198 million years ago.

Because its light is 198 million ly from home, you are seeing NGC 3459 as it looked roughly 198 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.
