Scientists have found evidence the clouds of Uranus are comprised of hydrogen sulfide which is pretty smelly stuff.

A paper published in N ature Astronomy explains the clouds have always appeared to be made up of ammonia or hydrogen sulfide but scientists had been unsure which until this recent survey using the Gemini-North Near-infrared Integral Field Spectrometer in Hawaii.Previous observations indicated Uranus's cloud top of the main cloud deck had pressures levels between 1.2 bar and 3 bar leading scientists to believe the clouds consisted of either ammonia or hydrogen sulfide but enough information was not available to ascertain in what quantities.With this new study, hydrogen sulfide has been detected in amounts as strong as 0.4 - 0.8 parts per million in the tops of the Uranus's cloud deck and less ammonia was found than originally expected, making hydrogen sulfide the main constituent of this portion of the planet's clouds.Incidentally, this concentration is also just strong enough to produce the rotten-egg smell the molecule is known for, confirming that Uranus smells...and it's probably like a fart.While it doesn't smell very good, we're sure Uranus is still beautiful, much like the larger gas giant Jupiter in these stunning photos For more amazing things about space, NASA is working to destroy a large asteroid which could collide with Earth as well as send a much smaller rock back to Mars
