NGC 7687

NGC 7687 is a lenticular galaxy in the constellation Pisces about 217 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 217 million years ago.

Because its light is 217 million ly from home, you are seeing NGC 7687 as it looked roughly 217 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.
