IC 4384

IC 4384 is a lenticular galaxy in the constellation Boötes about 487 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 10,397 km/s.

Because its light is 487 million ly from home, you are seeing IC 4384 as it looked roughly 487 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.
