IC 4027

IC 4027 is a lenticular galaxy in the constellation Canes Venatici about 497 million ly from Earth. It spans roughly 65,000 ly, about 65% of our Milky Way's width. The light reaching us tonight left it about 497 million years ago.

Because its light is 497 million ly from home, you are seeing IC 4027 as it looked roughly 497 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.
