IC 3515

IC 3515 is a barred spiral galaxy in the constellation Coma Berenices about 326 million ly from Earth. It spans roughly 62,000 ly, about 62% of our Milky Way's width. The light reaching us tonight left it about 326 million years ago.

Because its light is 326 million ly from home, you are seeing IC 3515 as it looked roughly 326 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.
