NGC 3844

NGC 3844 is a lenticular galaxy in the constellation Leo about 317 million ly from Earth. It spans roughly 110,000 ly, about the width of our Milky Way. It is receding from us at about 6,829 km/s.

Because its light is 317 million ly from home, you are seeing NGC 3844 as it looked roughly 317 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.
