NGC 4704

NGC 4704 is a barred spiral galaxy in the constellation Canes Venatici about 381 million ly from Earth. It spans roughly 110,000 ly, about the width of our Milky Way. It is receding from us at about 8,098 km/s.

Because its light is 381 million ly from home, you are seeing NGC 4704 as it looked roughly 381 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.
