NGC 5475

NGC 5475 is a spiral galaxy in the constellation Ursa Major about 78 million ly from Earth. It spans roughly 44,000 ly, about 44% of our Milky Way's width. It is receding from us at about 1,720 km/s.

Because its light is 78 million ly from home, you are seeing NGC 5475 as it looked roughly 78 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.
