NGC 3753

NGC 3753 is a barred spiral galaxy in the constellation Leo about 406 million ly from Earth. It spans roughly 190,000 ly, about 1.9 times the width of our Milky Way. It is receding from us at about 8,717 km/s.

Because its light is 406 million ly from home, you are seeing NGC 3753 as it looked roughly 406 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.
