NGC 293

NGC 293

NGC 293 is a barred spiral galaxy in the constellation Cetus about 262 million ly from Earth. It spans roughly 86,000 ly, about the width of our Milky Way. 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 293 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.
