This Planet Is on Fire and Also Frozen
Gliese 436 b is a planet the size of Neptune that orbits a red dwarf called Gliese 436. Gliese 436 b isn't like other planets, though. According to NASA, it has over 7,000 times less methane than it's supposed to. It also contains too many carbon monoxide molecules. The strangest thing yet? The planet is covered in an ice-like substance called Ice-x which, somehow remains at a blisteringly hot temperature. Astrologers still haven't figured out what's responsible for this phenomenon.
