IC 4275

IC 4275

IC 4275 is a barred spiral galaxy in the constellation Hydra about 204 million ly from Earth. It spans roughly 56,000 ly, about 56% of our Milky Way's width. It is receding from us at about 4,467 km/s.

Because its light is 204 million ly from home, you are seeing IC 4275 as it looked roughly 204 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.
