NGC 3514

NGC 3514 is a spiral galaxy in the constellation Crater about 160 million ly from Earth. It spans roughly 57,000 ly, about 57% of our Milky Way's width. The light reaching us tonight left it about 160 million years ago.

Because its light is 160 million ly from home, you are seeing NGC 3514 as it looked roughly 160 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.
