IC 4831

IC 4831

IC 4831 is a barred spiral galaxy in the constellation Pavo about 204 million ly from Earth. It spans roughly 220,000 ly, about 2.2 times the width of our Milky Way. It is receding from us at about 4,314 km/s.

Because its light is 204 million ly from home, you are seeing IC 4831 as it looked roughly 204 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.
