NGC 1157

NGC 1157 is a barred spiral galaxy in the constellation Eridanus about 419 million ly from Earth. It spans roughly 88,000 ly, about the width of our Milky Way. The light reaching us tonight left it about 419 million years ago.

Because its light is 419 million ly from home, you are seeing NGC 1157 as it looked roughly 419 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.
