NGC 5011A

NGC 5011A is a spiral galaxy in the constellation Centaurus about 144 million ly from Earth. It spans roughly 66,000 ly, about 66% of our Milky Way's width. It is receding from us at about 3,096 km/s.

Because its light is 144 million ly from home, you are seeing NGC 5011A as it looked roughly 144 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.
