NGC 3910

NGC 3910 is an elliptical galaxy in the constellation Leo about 365 million ly from Earth. It spans roughly 150,000 ly, about 1.5 times the width of our Milky Way. It is receding from us at about 7,833 km/s.

Because its light is 365 million ly from home, you are seeing NGC 3910 as it looked roughly 365 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.
