NGC 3415

NGC 3415 is a lenticular galaxy in the constellation Ursa Major about 152 million ly from Earth. It spans roughly 60,000 ly, about 60% of our Milky Way's width. It is receding from us at about 3,177 km/s.

Because its light is 152 million ly from home, you are seeing NGC 3415 as it looked roughly 152 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.
