IC 291

IC 291 is a lenticular galaxy in the constellation Eridanus about 194 million ly from Earth. It spans roughly 67,000 ly, about 67% of our Milky Way's width. The light reaching us tonight left it about 194 million years ago.

Because its light is 194 million ly from home, you are seeing IC 291 as it looked roughly 194 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.
