IC 1375

IC 1375 is an elliptical galaxy in the constellation Equuleus about 537 million ly from Earth. It spans roughly 91,000 ly, about the width of our Milky Way. The light reaching us tonight left it about 537 million years ago.

Because its light is 537 million ly from home, you are seeing IC 1375 as it looked roughly 537 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.
