IC 1079

IC 1079 is an elliptical galaxy in the constellation Boötes about 406 million ly from Earth. It spans roughly 170,000 ly, about 1.7 times the width of our Milky Way. The light reaching us tonight left it about 406 million years ago.

Because its light is 406 million ly from home, you are seeing IC 1079 as it looked roughly 406 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.
