IC 4436

IC 4436 is an elliptical galaxy in the constellation Boötes about 454 million ly from Earth. It spans roughly 160,000 ly, about 1.6 times the width of our Milky Way. It is receding from us at about 9,734 km/s.

Because its light is 454 million ly from home, you are seeing IC 4436 as it looked roughly 454 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.
