NGC 245

NGC 245

NGC 245 is a barred spiral galaxy in the constellation Cetus about 192 million ly from Earth. It spans roughly 67,000 ly, about 67% of our Milky Way's width. It is receding from us at about 4,123 km/s.

Because its light is 192 million ly from home, you are seeing NGC 245 as it looked roughly 192 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.
