IC 4395

IC 4395 is a spiral galaxy in the constellation Boötes about 511 million ly from Earth. It spans roughly 170,000 ly, about 1.7 times the width of our Milky Way. It is receding from us at about 10,962 km/s.

Because its light is 511 million ly from home, you are seeing IC 4395 as it looked roughly 511 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.
