IC 1841

IC 1841 is a barred spiral galaxy in the constellation Aries about 659 million ly from Earth. It spans roughly 120,000 ly, about the width of our Milky Way. The light reaching us tonight left it about 659 million years ago.

Because its light is 659 million ly from home, you are seeing IC 1841 as it looked roughly 659 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.
