IC 1809

IC 1809 is a barred spiral galaxy in the constellation Aries about 260 million ly from Earth. It spans roughly 64,000 ly, about 64% of our Milky Way's width. The light reaching us tonight left it about 260 million years ago.

Because its light is 260 million ly from home, you are seeing IC 1809 as it looked roughly 260 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.
