NGC 5312

NGC 5312 is a lenticular galaxy in the constellation Canes Venatici about 200 million ly from Earth. It spans roughly 63,000 ly, about 63% of our Milky Way's width. The light reaching us tonight left it about 200 million years ago.

Because its light is 200 million ly from home, you are seeing NGC 5312 as it looked roughly 200 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.
