IC 3149

IC 3149 is a lenticular galaxy in the constellation Virgo about 368 million ly from Earth. It spans roughly 68,000 ly, about 68% of our Milky Way's width. It is receding from us at about 8,127 km/s.

Because its light is 368 million ly from home, you are seeing IC 3149 as it looked roughly 368 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.
