IC 5253

IC 5253 is a lenticular galaxy in the constellation Pegasus about 330 million ly from Earth. It spans roughly 85,000 ly, about the width of our Milky Way. The light reaching us tonight left it about 330 million years ago.

Because its light is 330 million ly from home, you are seeing IC 5253 as it looked roughly 330 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.
