IC 5025
IC 5025 is a barred spiral galaxy in the constellation Octans about 306 million ly from Earth. It spans roughly 150,000 ly, about the width of our Milky Way. The light reaching us tonight left it about 306 million years ago.

Because its light is 306 million ly from home, you are seeing IC 5025 as it looked roughly 306 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.
