IC 3815

IC 3815 is a barred spiral galaxy in the constellation Coma Berenices about 908 million ly from Earth. It spans roughly 150,000 ly, about the width of our Milky Way. The light reaching us tonight left it about 908 million years ago.

Because its light is 908 million ly from home, you are seeing IC 3815 as it looked roughly 908 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.
