NGC 3720

NGC 3720 is a spiral galaxy in the constellation Leo about 277 million ly from Earth. It spans roughly 86,000 ly, about the width of our Milky Way. It is receding from us at about 5,958 km/s.

Because its light is 277 million ly from home, you are seeing NGC 3720 as it looked roughly 277 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.
