IC 4058

IC 4058 is a barred spiral galaxy in the constellation Coma Berenices about 916 million ly from Earth. It spans roughly 170,000 ly, about 1.7 times the width of our Milky Way. The light reaching us tonight left it about 916 million years ago.

Because its light is 916 million ly from home, you are seeing IC 4058 as it looked roughly 916 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.
