NGC 7215

NGC 7215 is a lenticular galaxy in the constellation Aquarius about 187 million ly from Earth. It spans roughly 49,000 ly, about 49% of our Milky Way's width. The light reaching us tonight left it about 187 million years ago.

Because its light is 187 million ly from home, you are seeing NGC 7215 as it looked roughly 187 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.
