NGC 6870

NGC 6870 is a spiral galaxy in the constellation Telescopium about 128 million ly from Earth. It spans roughly 95,000 ly, about the width of our Milky Way. It is receding from us at about 2,736 km/s.

Because its light is 128 million ly from home, you are seeing NGC 6870 as it looked roughly 128 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.
