NGC 1207

NGC 1207

NGC 1207 is a barred spiral galaxy in the constellation Perseus about 223 million ly from Earth. It spans roughly 110,000 ly, about the width of our Milky Way. It is receding from us at about 4,787 km/s.

Because its light is 223 million ly from home, you are seeing NGC 1207 as it looked roughly 223 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.
