IC 2563

IC 2563 is a barred spiral galaxy in the constellation Antlia about 64 million ly from Earth. It spans roughly 17,000 ly, about 17% of our Milky Way's width. The light reaching us tonight left it about 64 million years ago.

Because its light is 64 million ly from home, you are seeing IC 2563 as it looked roughly 64 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.
