NGC 5365A

NGC 5365A is a barred spiral galaxy in the constellation Centaurus about 128 million ly from Earth. It spans roughly 110,000 ly, about the width of our Milky Way. It is receding from us at about 2,740 km/s.

Because its light is 128 million ly from home, you are seeing NGC 5365A as it looked roughly 128 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.
