IC 910

IC 910 is a spiral galaxy in the constellation Boötes about 377 million ly from Earth. It spans roughly 75,000 ly, about 75% of our Milky Way's width. It is receding from us at about 8,133 km/s.

Because its light is 377 million ly from home, you are seeing IC 910 as it looked roughly 377 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.
