NGC 3756

NGC 3756 is a spiral galaxy in the constellation Ursa Major about 60 million ly from Earth. It spans roughly 33,000 ly, about 33% of our Milky Way's width. It is receding from us at about 1,071 km/s.

Because its light is 60 million ly from home, you are seeing NGC 3756 as it looked roughly 60 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.
