NGC 3300

NGC 3300 is a lenticular galaxy in the constellation Leo about 141 million ly from Earth. It spans roughly 63,000 ly, about 63% of our Milky Way's width. It is receding from us at about 3,045 km/s.

Because its light is 141 million ly from home, you are seeing NGC 3300 as it looked roughly 141 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.
