IC 964

IC 964 is a barred spiral galaxy in the constellation Boötes about 311 million ly from Earth. It spans roughly 58,000 ly, about 58% of our Milky Way's width. The light reaching us tonight left it about 311 million years ago.

Because its light is 311 million ly from home, you are seeing IC 964 as it looked roughly 311 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.
