NGC 5605

NGC 5605 is a spiral galaxy in the constellation Libra about 158 million ly from Earth. It spans roughly 69,000 ly, about 69% of our Milky Way's width. The light reaching us tonight left it about 158 million years ago.

Because its light is 158 million ly from home, you are seeing NGC 5605 as it looked roughly 158 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.
