NGC 3529

NGC 3529 is a barred spiral galaxy in the constellation Crater about 175 million ly from Earth. It spans roughly 56,000 ly, about 56% of our Milky Way's width. The light reaching us tonight left it about 175 million years ago.

Because its light is 175 million ly from home, you are seeing NGC 3529 as it looked roughly 175 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.
