IC 4782

IC 4782 is a spiral galaxy in the constellation Telescopium about 134 million ly from Earth. It spans roughly 16,000 ly, about 16% of our Milky Way's width. The light reaching us tonight left it about 134 million years ago.

Because its light is 134 million ly from home, you are seeing IC 4782 as it looked roughly 134 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.
