IC 3155

IC 3155 is a lenticular galaxy in the constellation Virgo about 105 million ly from Earth. It spans roughly 30,000 ly, about 30% of our Milky Way's width. It is receding from us at about 2,062 km/s.

Because its light is 105 million ly from home, you are seeing IC 3155 as it looked roughly 105 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.
