NGC 3664

NGC 3664 is a barred spiral galaxy in the constellation Leo about 64 million ly from Earth. It spans roughly 27,000 ly, about 27% of our Milky Way's width. It is receding from us at about 1,362 km/s.

Because its light is 64 million ly from home, you are seeing NGC 3664 as it looked roughly 64 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.
