IC 4492

IC 4492 is an elliptical galaxy in the constellation Boötes about 192 million ly from Earth. It spans roughly 35,000 ly, about 35% of our Milky Way's width. The light reaching us tonight left it about 192 million years ago.

Because its light is 192 million ly from home, you are seeing IC 4492 as it looked roughly 192 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.
