NGC 3727

NGC 3727 is a lenticular galaxy in the constellation Crater about 215 million ly from Earth. It spans roughly 58,000 ly, about 58% of our Milky Way's width. The light reaching us tonight left it about 215 million years ago.

Because its light is 215 million ly from home, you are seeing NGC 3727 as it looked roughly 215 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.
