NGC 5215A

NGC 5215A is a lenticular galaxy in the constellation Centaurus about 178 million ly from Earth. It spans roughly 81,000 ly, about 81% of our Milky Way's width. It is receding from us at about 3,911 km/s.

Because its light is 178 million ly from home, you are seeing NGC 5215A as it looked roughly 178 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.
