IC 3008

IC 3008 is a barred spiral galaxy in the constellation Coma Berenices about 325 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 325 million years ago.

Because its light is 325 million ly from home, you are seeing IC 3008 as it looked roughly 325 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.
