IC 1833

IC 1833

IC 1833 is a lenticular galaxy in the constellation Fornax about 230 million ly from Earth. It spans roughly 95,000 ly, about the width of our Milky Way. It is receding from us at about 4,937 km/s.

Because its light is 230 million ly from home, you are seeing IC 1833 as it looked roughly 230 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.
