IC 4777

IC 4777 is a lenticular galaxy in the constellation Telescopium about 258 million ly from Earth. It spans roughly 70,000 ly, about 70% of our Milky Way's width. It is receding from us at about 5,555 km/s.

Because its light is 258 million ly from home, you are seeing IC 4777 as it looked roughly 258 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.
