NGC 4712

NGC 4712 is a barred spiral galaxy in the constellation Coma Berenices about 204 million ly from Earth. It spans roughly 93,000 ly, about the width of our Milky Way. It is receding from us at about 4,462 km/s.

Because its light is 204 million ly from home, you are seeing NGC 4712 as it looked roughly 204 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.
