IC 4448

IC 4448

IC 4448 is a barred spiral galaxy in the constellation Apus about 214 million ly from Earth. It spans roughly 69,000 ly, about 69% of our Milky Way's width. It is receding from us at about 4,618 km/s.

Because its light is 214 million ly from home, you are seeing IC 4448 as it looked roughly 214 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.
