IC 2435

IC 2435 is an elliptical galaxy in the constellation Cancer about 288 million ly from Earth. It spans roughly 74,000 ly, about 74% of our Milky Way's width. The light reaching us tonight left it about 288 million years ago.

Because its light is 288 million ly from home, you are seeing IC 2435 as it looked roughly 288 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.
