Here's a crazy idea...
Could some form of life exist in such harsh conditions? It doesn't necessarily have to have originated there, but I'm sure it would help.
I know the following extremes are mild compared to what's on that exoworld, but think of the life forms on Earth that thrive around boiling hydrothermal vents on the ocean floors, the microbes that live in solid rock miles underground, and the little creatures that enjoy swimming in highly acidic geyser pools and the intense radiation from nuclear power plants.
