NGC 4945A

NGC 4945A is a spiral galaxy in the constellation Centaurus about 64 million ly from Earth. It spans roughly 49,000 ly, about 49% of our Milky Way's width. It is receding from us at about 1,367 km/s.

Because its light is 64 million ly from home, you are seeing NGC 4945A as it looked roughly 64 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.
