NGC 7189

NGC 7189

NGC 7189 is a barred spiral galaxy in the constellation Aquarius about 420 million ly from Earth. It spans roughly 120,000 ly, about the width of our Milky Way. It is receding from us at about 9,125 km/s.

Because its light is 420 million ly from home, you are seeing NGC 7189 as it looked roughly 420 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.
