IC 1129

IC 1129 is a spiral galaxy in the constellation Ursa Minor about 305 million ly from Earth. It spans roughly 89,000 ly, about the width of our Milky Way. The light reaching us tonight left it about 305 million years ago.

Because its light is 305 million ly from home, you are seeing IC 1129 as it looked roughly 305 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.
