IC 4219

IC 4219 is a barred spiral galaxy in the constellation Centaurus about 171 million ly from Earth. It spans roughly 56,000 ly, about 56% of our Milky Way's width. It is receding from us at about 3,647 km/s.

Because its light is 171 million ly from home, you are seeing IC 4219 as it looked roughly 171 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.
