IC 2573
IC 2573 is a barred spiral galaxy in the constellation Antlia about 194 million ly from Earth. It spans roughly 85,000 ly, about 85% 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 2573 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.
