NGC 6636 NED02

NGC 6636 NED02 is a spiral galaxy in the constellation Draco about 210 million ly from Earth. It spans roughly 44,000 ly, about 44% of our Milky Way's width. The light reaching us tonight left it about 210 million years ago.

Because its light is 210 million ly from home, you are seeing NGC 6636 NED02 as it looked roughly 210 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.
