NGC 1305

NGC 1305 is an elliptical galaxy in the constellation Eridanus about 290 million ly from Earth. It spans roughly 110,000 ly, about the width of our Milky Way. The light reaching us tonight left it about 290 million years ago.

Because its light is 290 million ly from home, you are seeing NGC 1305 as it looked roughly 290 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.
