NGC 1540A

NGC 1540A is a spiral galaxy in the constellation Eridanus about 262 million ly from Earth. It spans roughly 43,000 ly, about 43% of our Milky Way's width. The light reaching us tonight left it about 262 million years ago.

Because its light is 262 million ly from home, you are seeing NGC 1540A as it looked roughly 262 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.
