IC 4909

IC 4909 is a barred spiral galaxy in the constellation Telescopium about 351 million ly from Earth. It spans roughly 120,000 ly, about the width of our Milky Way. It is receding from us at about 8,100 km/s.

Because its light is 351 million ly from home, you are seeing IC 4909 as it looked roughly 351 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.
