NGC 6845A

NGC 6845A is a barred spiral galaxy in the constellation Telescopium about 299 million ly from Earth. It spans roughly 94,000 ly, about the width of our Milky Way. It is receding from us at about 6,356 km/s.

Because its light is 299 million ly from home, you are seeing NGC 6845A as it looked roughly 299 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.
