NGC 3161

NGC 3161 is an elliptical galaxy in the constellation Leo Minor about 293 million ly from Earth. It spans roughly 39,000 ly, about 39% of our Milky Way's width. It is receding from us at about 6,171 km/s.

Because its light is 293 million ly from home, you are seeing NGC 3161 as it looked roughly 293 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.
