IC 150

IC 150 is a barred spiral galaxy in the constellation Pisces about 259 million ly from Earth. It spans roughly 66,000 ly, about 66% of our Milky Way's width. The light reaching us tonight left it about 259 million years ago.

Because its light is 259 million ly from home, you are seeing IC 150 as it looked roughly 259 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.
