IC 1405

IC 1405

IC 1405 is a spiral galaxy in the constellation Aquarius about 361 million ly from Earth. It spans roughly 91,000 ly, about the width of our Milky Way. The light reaching us tonight left it about 361 million years ago.

Because its light is 361 million ly from home, you are seeing IC 1405 as it looked roughly 361 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.
