NGC 5554

NGC 5554 is a barred spiral galaxy in the constellation Virgo about 350 million ly from Earth. It spans roughly 66,000 ly, about 66% of our Milky Way's width. The light reaching us tonight left it about 350 million years ago.

Because its light is 350 million ly from home, you are seeing NGC 5554 as it looked roughly 350 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.
