NGC 3654

NGC 3654 is a barred spiral galaxy in the constellation Ursa Major about 73 million ly from Earth. It spans roughly 31,000 ly, about 31% of our Milky Way's width. It is receding from us at about 1,579 km/s.

Because its light is 73 million ly from home, you are seeing NGC 3654 as it looked roughly 73 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.
