Scientists have lots of questions about Uranus.
Why does Uranus look the way it does, why did Uranus form the way it did, why does Uranus differ so much from other gas giants, like Jupiter and Saturn?
“It’s so cold that there’s not much” in the way of the compounds that we can smell, Jonathan Fortney, director of the Other Worlds Laboratory at the University of California, Santa Cruz, told Gizmodo.
“A lot of the things you’d normally think of as volatile gasses,” the smelly ones, “have frozen out of the clouds.”
Also, if you went to Uranus to try to smell its atmosphere, you’d die.
“You wouldn’t want to be in that atmosphere trying to breathe,” Mark Hofstadter, Planetary Scientist at NASA’s Jet Propulsion Laboratory, told Gizmodo.
