NGC 3594

NGC 3594 is a lenticular galaxy in the constellation Ursa Major about 463 million ly from Earth. It spans roughly 170,000 ly, about 1.7 times the width of our Milky Way. It is receding from us at about 6,257 km/s.

Because its light is 463 million ly from home, you are seeing NGC 3594 as it looked roughly 463 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.
