NGC 3427

NGC 3427 is a lenticular galaxy in the constellation Leo about 297 million ly from Earth. It spans roughly 110,000 ly, about the width of our Milky Way. It is receding from us at about 6,263 km/s.

Because its light is 297 million ly from home, you are seeing NGC 3427 as it looked roughly 297 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.
