NGC 3499

NGC 3499 is a lenticular galaxy in the constellation Ursa Major about 71 million ly from Earth. It spans roughly 17,000 ly, about 17% of our Milky Way's width. It is receding from us at about 1,559 km/s.

Because its light is 71 million ly from home, you are seeing NGC 3499 as it looked roughly 71 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.
