NGC 4446

NGC 4446 is a spiral galaxy in the constellation Coma Berenices about 341 million ly from Earth. It spans roughly 97,000 ly, about the width of our Milky Way. It is receding from us at about 7,342 km/s.

Because its light is 341 million ly from home, you are seeing NGC 4446 as it looked roughly 341 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.
