IC 3287

IC 3287 is a spiral galaxy in the constellation Coma Berenices about 759 million ly from Earth. It spans roughly 46,000 ly, about 46% of our Milky Way's width. The light reaching us tonight left it about 759 million years ago.

Because its light is 759 million ly from home, you are seeing IC 3287 as it looked roughly 759 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.
