NGC 2577

NGC 2577 is an elliptical galaxy in the constellation Cancer about 99 million ly from Earth. It spans roughly 44,000 ly, about 44% of our Milky Way's width. It is receding from us at about 2,145 km/s.

Because its light is 99 million ly from home, you are seeing NGC 2577 as it looked roughly 99 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.
