NGC 3126

NGC 3126 is a spiral galaxy in the constellation Leo Minor about 239 million ly from Earth. It spans roughly 220,000 ly, about 2.2 times the width of our Milky Way. It is receding from us at about 5,144 km/s.

Because its light is 239 million ly from home, you are seeing NGC 3126 as it looked roughly 239 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.
