Well, we basically have a good idea of this, and the answer is no, there isn't. No animal could survive
in these hazardus conditions, however we could imagine a Neptunian. Forget bones, skin, blood,
eyes, fur, ect. at temperatures like this any alien would be made up purely from electromagnetic energy, so it would be a
series of bleeps, maybe with a few gamma rays and a handful of photons chucked in. Such an animal probably wouldn't be able
to exist, but maybe, just maybe.
