NGC 4696D

NGC 4696D is a lenticular galaxy in the constellation Centaurus about 121 million ly from Earth. It spans roughly 48,000 ly, about 48% of our Milky Way's width. It is receding from us at about 2,590 km/s.

Because its light is 121 million ly from home, you are seeing NGC 4696D as it looked roughly 121 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.
