NGC 5101

NGC 5101 is a lenticular galaxy in the constellation Hydra about 87 million ly from Earth. It spans roughly 150,000 ly, about 1.5 times the width of our Milky Way. It is receding from us at about 1,840 km/s.

Because its light is 87 million ly from home, you are seeing NGC 5101 as it looked roughly 87 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.
