IC 2143

IC 2143 is a barred spiral galaxy in the constellation Lepus about 143 million ly from Earth. It spans roughly 79,000 ly, about 79% of our Milky Way's width. It is receding from us at about 3,134 km/s.

Because its light is 143 million ly from home, you are seeing IC 2143 as it looked roughly 143 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.
