NGC 3182

NGC 3182 is a lenticular galaxy in the constellation Ursa Major about 99 million ly from Earth. It spans roughly 55,000 ly, about 55% of our Milky Way's width. It is receding from us at about 2,130 km/s.

Because its light is 99 million ly from home, you are seeing NGC 3182 as it looked roughly 99 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.
