NGC 3617

NGC 3617 is an elliptical galaxy in the constellation Hydra about 102 million ly from Earth. It spans roughly 53,000 ly, about 53% of our Milky Way's width. It is receding from us at about 2,199 km/s.

Because its light is 102 million ly from home, you are seeing NGC 3617 as it looked roughly 102 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.
