IC 3271

IC 3271 is a spiral galaxy in the constellation Virgo about 337 million ly from Earth. It spans roughly 78,000 ly, about 78% of our Milky Way's width. The light reaching us tonight left it about 337 million years ago.

Because its light is 337 million ly from home, you are seeing IC 3271 as it looked roughly 337 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.
