IC 4692

IC 4692

IC 4692 is a barred spiral galaxy in the constellation Pavo about 227 million ly from Earth. It spans roughly 120,000 ly, about the width of our Milky Way. The light reaching us tonight left it about 227 million years ago.

Because its light is 227 million ly from home, you are seeing IC 4692 as it looked roughly 227 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.
