IC 4797

IC 4797 is an elliptical galaxy in the constellation Telescopium about 124 million ly from Earth. It spans roughly 95,000 ly, about the width of our Milky Way. It is receding from us at about 2,678 km/s.

Because its light is 124 million ly from home, you are seeing IC 4797 as it looked roughly 124 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.
