NGC 3364

NGC 3364 is a spiral galaxy in the constellation Ursa Major about 126 million ly from Earth. It spans roughly 51,000 ly, about 51% of our Milky Way's width. It is receding from us at about 2,713 km/s.

Because its light is 126 million ly from home, you are seeing NGC 3364 as it looked roughly 126 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.
