NGC 3271

NGC 3271 is a lenticular galaxy in the constellation Antlia about 175 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 3,794 km/s.

Because its light is 175 million ly from home, you are seeing NGC 3271 as it looked roughly 175 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.
