NGC 1691

NGC 1691 is a lenticular galaxy in the constellation Orion about 215 million ly from Earth. It spans roughly 96,000 ly, about the width of our Milky Way. It is receding from us at about 4,590 km/s.

Because its light is 215 million ly from home, you are seeing NGC 1691 as it looked roughly 215 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.
