NGC 169

NGC 169 is a spiral galaxy in the constellation Andromeda about 213 million ly from Earth. It spans roughly 95,000 ly, about the width of our Milky Way. It is receding from us at about 4,507 km/s.

Because its light is 213 million ly from home, you are seeing NGC 169 as it looked roughly 213 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.
