NGC 7311

NGC 7311 is a spiral galaxy in the constellation Pegasus about 211 million ly from Earth. It spans roughly 90,000 ly, about the width of our Milky Way. It is receding from us at about 4,462 km/s.

Because its light is 211 million ly from home, you are seeing NGC 7311 as it looked roughly 211 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.
