(CNN) - Scientists released a new study that suggests that Uranus smells like rotten eggs.
University of Oxford researchers said clouds in the planet's atmosphere are composed of hydrogen sulfide, the molecule that makes rotten eggs smell so bad.
But how did experts sniff out this new info from roughly 1.6 billion miles away?
Researchers used a spectrometer on NASA's Gemini telescope in Hawaii to observe the planet's cloud cover.
That's where they spotted the signature of hydrogen sulfide.
However, experts said if anyone were to go to Uranus, they wouldn't have to endure the stench.
Suffocation and minus-200-degree atmospheric conditions would likely kill them first.
