NGC 238

NGC 238

NGC 238 is a barred spiral galaxy in the constellation Phoenix about 407 million ly from Earth. It spans roughly 240,000 ly, about 2.4 times the width of our Milky Way. It is receding from us at about 8,621 km/s.

Because its light is 407 million ly from home, you are seeing NGC 238 as it looked roughly 407 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.
