IC 4525

IC 4525 is a barred spiral galaxy in the constellation Boötes about 459 million ly from Earth. It spans roughly 77,000 ly, about 77% of our Milky Way's width. The light reaching us tonight left it about 459 million years ago.

Because its light is 459 million ly from home, you are seeing IC 4525 as it looked roughly 459 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.
