IC 3759

IC 3759 is a spiral galaxy in the constellation Coma Berenices about 327 million ly from Earth. It spans roughly 59,000 ly, about 59% of our Milky Way's width. The light reaching us tonight left it about 327 million years ago.

Because its light is 327 million ly from home, you are seeing IC 3759 as it looked roughly 327 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.
