IC 2582

IC 2582 is a barred spiral galaxy in the constellation Antlia about 193 million ly from Earth. It spans roughly 72,000 ly, about 72% of our Milky Way's width. It is receding from us at about 4,210 km/s.

Because its light is 193 million ly from home, you are seeing IC 2582 as it looked roughly 193 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.
