IC 3147 NED01
IC 3147 NED01 is a spiral galaxy in the constellation Virgo about 363 million ly from Earth. It spans roughly 70,000 ly, about 70% of our Milky Way's width. The light reaching us tonight left it about 363 million years ago.

Because its light is 363 million ly from home, you are seeing IC 3147 NED01 as it looked roughly 363 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.
