NGC 5321

NGC 5321 is a lenticular galaxy in the constellation Canes Venatici about 216 million ly from Earth. It spans roughly 56,000 ly, about 56% of our Milky Way's width. The light reaching us tonight left it about 216 million years ago.

Because its light is 216 million ly from home, you are seeing NGC 5321 as it looked roughly 216 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.
