NGC 3495

NGC 3495 is a spiral galaxy in the constellation Leo about 52 million ly from Earth. It spans roughly 71,000 ly, about 71% of our Milky Way's width. It is receding from us at about 1,086 km/s.

Because its light is 52 million ly from home, you are seeing NGC 3495 as it looked roughly 52 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.
