IC 1931
IC 1931 is a galaxy in the constellation Taurus about 434 million ly from Earth. It spans roughly 100,000 ly, about the width of our Milky Way. The light reaching us tonight left it about 434 million years ago.

Because its light is 434 million ly from home, you are seeing IC 1931 as it looked roughly 434 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.
