Quiz Question: Why might Uranus’ atmosphere smell like rotten eggs?
The given options are:
- Methane
- Hydrogen sulfide
- Cosmic waste
Correct Answer: Hydrogen sulfide
Info: It’s a good thing Uranus is so far from Earth with all that smelly gas floating around. The clouds in the planet’s upper atmosphere contain hydrogen sulfide, which is what gives rotten eggs their undeniable stench. Given the planet’s name, jokes about its stinky atmosphere write themselves, so we won’t bother to stoop so low.
