NGC 3153

NGC 3153 is a spiral galaxy in the constellation Leo about 131 million ly from Earth. It spans roughly 66,000 ly, about 66% of our Milky Way's width. It is receding from us at about 2,827 km/s.

Because its light is 131 million ly from home, you are seeing NGC 3153 as it looked roughly 131 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.
