NGC 7446

NGC 7446 is an elliptical galaxy in the constellation Andromeda about 254 million ly from Earth. It spans roughly 93,000 ly, about the width of our Milky Way. The light reaching us tonight left it about 254 million years ago.

Because its light is 254 million ly from home, you are seeing NGC 7446 as it looked roughly 254 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.
