The planet Uranus has clouds made up of hydrogen sulphide, the gas that gives rotten eggs their unpleasant smell.
The possibility of this gas being present in the atmosphere of the seventh planet had long been debated, but has now been confirmed for the first time by observations at a telescope on Hawaii.
The malodorous gas was detected high above the giant planet's cloud tops.
The findings could shed important new light on how the outer planets formed.
A team of researchers have published their results in the journal Nature Astronomy.
Despite previous observations by ground telescopes and the Voyager 2 spacecraft, the composition of Uranus' atmosphere had remained unclear.
Scientists have long wondered whether hydrogen sulphide (H₂S) or ammonia (NH₃) dominate the ice giant's cloud deck, but have lacked definitive evidence either way.
The data were obtained with the Near-Infrared Integral Field Spectrometer (NIFS) instrument on the Gemini North telescope on Hawaii's Mauna Kea summit.
The spectroscopic measurements break infrared light from Uranus into its component wavelengths. Bands in the resulting spectrum known as absorption lines, where the gas absorbs infrared light coming from the Sun, allowed the scientists to "fingerprint" components of Uranus' atmosphere.
"Now, thanks to improved hydrogen sulphide absorption-line data and the wonderful Gemini spectra, we have the fingerprint which caught the culprit," said co-author Patrick Irwin, from the University of Oxford.

The detection of hydrogen sulphide high in Uranus' cloud deck, sets up a contrast with inner gas giant planets such as Jupiter and Saturn. The bulk of Jupiter and Saturn's upper clouds are instead comprised of ammonia ice.
The researchers say these differences in atmospheric composition shed light on questions about the planets' formation and history.
Co-author Dr Leigh Fletcher, from the University of Leicester, said that these differences were probably imprinted early on in the history of these worlds.
He explained that the balance between different gases in the atmospheres of these planets was probably determined by the conditions where they formed in the early Solar System.
According to Dr Fletcher, when a cloud deck forms by condensation, it locks away the cloud-forming gas in a deep internal reservoir, hidden away beneath the levels that we can usually see with our telescopes.
"Only a tiny amount remains above the clouds as a saturated vapour... and this is why it is so challenging to capture the signatures of ammonia and hydrogen sulphide above cloud decks of Uranus," he said.
"The superior capabilities of Gemini finally gave us that lucky break."
Glenn Orton, of Nasa's Jet Propulsion Laboratory (JPL) in Pasadena, who worked on the study, said: "We've strongly suspected that hydrogen sulphide gas was influencing the millimetre spectrum of Uranus for some time, but we were unable to attribute the absorption needed to it uniquely. Now, that part of the puzzle is falling into place as well."
Dr Irwin explained: "If an unfortunate human were ever to descend through Uranus's clouds, they would be met with very unpleasant and odiferous conditions."
But he added: "Suffocation and exposure in the negative 200 degrees Celsius atmosphere made of mostly hydrogen, helium, and methane would take its toll long before the smell."
Calm down, Bill Nye.
Just roll up with that Steam Umm's shirt on and you'll be good to go.
Better than that, ill be in the brew gentlemen line all day if anyone wants to stop by and say hi.

looks like there are still tix leftLooking forward to everyone who was whining on Facebook yesterday feverishly f5ing at 9 AM.

Commenting now to show my lolz if a festival only bottle happens and people are pissed about that too.
You would get one anyway, though.

So which of you miscreants are gonna go and stand in line on Saturday morning for BRC pourz?
Pours of what? Where did you see a taplist, or any info at?

I'll be in Boston for a wedding this weekend but I'll enjoy reading all the hot takes on Untappd. That's the only thing that app is good for.
What hot takes? Every time I go to that site to look for reviews on beer, all I see are stars, badges and pictures, but RARELY see any actual feedback on the beer via words. I ******* hate that site and I'm not sure how it got to be a thing.
It's a way to keep track of your ticks. Didn't you keep ticks on BA for like, ever?
A social excel file.
Still kind of do when I remember. And would probably switch untappd if I could transfer all those ticks over somehow solely because that's where all new beers seem to get added now. Other than that specific thing, it's poop...especially for "hot takes".
But to be fair, I think that's just the way it is now...untappd is just giving the people what they want. A social excel file.
I've checked in 1364 unique beers and still haven't gotten laid.

Don't forget about the Otterbois that'll trash the vanilla one for being a pastrywine.You know there will be at least 1 1-star review for The K13 with a note below saying "I don't like barleywines." That **** is just gold.
