NGC 6174 NED01

NGC 6174 NED01 is an elliptical galaxy in the constellation Hercules about 394 million ly from Earth. It spans roughly 47,000 ly, about 47% of our Milky Way's width. The light reaching us tonight left it about 394 million years ago.

Because its light is 394 million ly from home, you are seeing NGC 6174 NED01 as it looked roughly 394 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.
