NGC 7578B

NGC 7578B is an elliptical galaxy in the constellation Pegasus about 573 million ly from Earth. It spans roughly 290,000 ly, about 2.9 times the width of our Milky Way. It is receding from us at about 12,053 km/s.

Because its light is 573 million ly from home, you are seeing NGC 7578B as it looked roughly 573 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.
