A closer look
Uranus genuinely smells like rotten eggs due to the massive concentration of hydrogen sulfide in its upper atmospheric layers. Astronomers used sophisticated spectroscopic equipment to determine the chemical composition of the seventh planet from the sun, confirming what the oldest joke in the solar system has always implied. You have to appreciate the profound irony of an incredibly advanced, multi-million dollar space telescope being utilized to scientifically validate a literal fart joke. It is almost comforting to know that out there in the vast, terrifying emptiness of the cosmos, there is a giant blue orb silently reeking of flatulence. If we ever develop the technology to send a manned mission there, those brave astronauts will travel billions of miles just to be greeted by the scent of a poorly ventilated sulfur pit!
