IC 2900
IC 2900 is a barred spiral galaxy in the constellation Leo about 1.2 billion ly from Earth. It spans roughly 110,000 ly, about the width of our Milky Way. The light reaching us tonight left it about 1.2 billion years ago.

Because its light is 1.2 billion ly from home, you are seeing IC 2900 as it looked roughly 1.2 billion 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.
