Collision of Uranus Could Explain Two Other Oddities About Tilted Planet

The Smell of Uranus is Like Rotten Eggs: NASA Scientists Revealed

NASA scientists discovered that the smell of Uranus is extremely bad like rotten eggs. Uranus is the seventh planet from the Sun that has the third-largest planetary radius and fourth-largest planetary mass in the Solar System. Uranus’s mass is roughly 14.5 times that of Earth, and  its structure consists of three layers: a rocky core in the center, an icy mantle in the middle and an outer gaseous hydrogen/helium envelope. Finally, scientists discovered “one critical secret” in the composition of its clouds – the smell of Uranus, which is not a pleasant discovery. The smell of Uranus is extremely bad like rotten eggs due to the planet’s cloud tops containing hydrogen sulfide which is an odiferous gas.

NASA claimed “The detection of hydrogen sulfide high in Uranus’ cloud deck (and presumably Neptune’s) is a striking difference from the gas giant planets located closer to the Sun — Jupiter and Saturn — where ammonia is observed above the clouds, but no hydrogen sulfide. These differences in atmospheric composition shed light on questions about the planets’ formation and history”.

The findings were presented by the U.S. space agency, Gemini Observatory and in a study published in the Nature Astronomy journal.

NASA says it detected the hydrogen sulfide, “the gas that gives rotten eggs their distinctive odor,” using its Gemini North telescope on Hawaii’s Mauna Kea.

“While the lines we were trying to detect were just barely there, we were able to detect them unambiguously thanks to the sensitivity of NIFS on Gemini, combined with the exquisite conditions on Mauna Kea,” said lead author Patrick Irwin of the University of Oxford, U.K.

“We’ve strongly suspected that hydrogen sulfide gas was influencing the millimeter and radio spectrum of Uranus for some time, but we were unable to attribute the absorption needed to identify it positively. Now, that part of the puzzle is falling into place as well,” Orton said.

No worries, though, that the odor of hydrogen sulfide would overtake human senses. According to Irwin, “Suffocation and exposure in the negative 200 degrees Celsius [392 degrees Fahrenheit] atmosphere made of mostly hydrogen, helium and methane would take its toll long before the smell.”
