IC 3884

IC 3884 is a barred spiral galaxy in the constellation Coma Berenices about 903 million ly from Earth. It spans roughly 220,000 ly, about 2.2 times the width of our Milky Way. The light reaching us tonight left it about 903 million years ago.

Because its light is 903 million ly from home, you are seeing IC 3884 as it looked roughly 903 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.
