IC 309

IC 309 is a lenticular galaxy in the constellation Perseus about 195 million ly from Earth. It spans roughly 58,000 ly, about 58% of our Milky Way's width. It is receding from us at about 4,234 km/s.

Because its light is 195 million ly from home, you are seeing IC 309 as it looked roughly 195 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.
