NGC 1421

NGC 1421

NGC 1421 is a barred spiral galaxy in the constellation Eridanus about 97 million ly from Earth. It spans roughly 100,000 ly, about the width of our Milky Way. It is receding from us at about 2,081 km/s.

Because its light is 97 million ly from home, you are seeing NGC 1421 as it looked roughly 97 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.
