NGC 7121

NGC 7121

NGC 7121 is a barred spiral galaxy in the constellation Aquarius about 389 million ly from Earth. It spans roughly 130,000 ly, about the width of our Milky Way. The light reaching us tonight left it about 389 million years ago.

Because its light is 389 million ly from home, you are seeing NGC 7121 as it looked roughly 389 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.
