Rotten egg smell surrounds Uranus

Rotten egg smell surrounds Uranus

Uranus has fascinated astronomers for decades and, unfortunately, has also been the butt of jokes for many years (with regard to how its name is pronounced) and the latest discovery that the planet's clouds smell like rotten eggs or, fart, serves to establish that "uranus jokes" will continue for many more years to come.

The Near-Infrared Integral Field Spectrometer (NIFS) on Gemini filters the sunlight reflected above the clouds in Uranus' atmosphere into spectral lines that describe what the gas molecules are made of.

A recent study analyzing data collected more than 30 years ago by the Voyager 2 spacecraft has found that the Uranus's global magnetosphere is nothing like Earth's, which is known to be aligned almost with our planet's spin axis.

"If an unfortunate human were ever to descend through Uranus' clouds, they would be met with very unpleasant and odiferous conditions", said Patrick Irwin, first author of the study and a physics professor at the University of Oxford.

Several scientists have always thought that the clouds near the giant green planet's surface contain hydrogen sulfide and ammonia, but it was always an assumption rather than a observation.

Scientists have determined that the atmosphere above the planet Uranus is full of a gas that makes the distant planet smell like rotten eggs. Spectroscopic measurements work by breaking down infrared (IR) light from the source - Uranus- into component wavelengths.

Google owner Alphabet reports 84% rise in profits despite privacy concerns
BidaskClub raised shares of Alphabet from a "buy" rating to a "strong-buy" rating in a research report on Wednesday, January 10th. Porat said the heaviest spending came from research and development costs - mainly the hiring of additional technical staff.

Although many mysteries of the solar system have been revealed as of now; but still the universe has abundant secrets in its pocket. These planets have thick atmospheres filled with upper clouds of ammonia ice.

The planets in our solar system can have dramatically different cloud decks based on how they were formed, the researchers explain. This is an observation that contrasts sharply with the inner gas giant planets Jupiter and Saturn, where no hydrogen sulfide is seen above the clouds - instead, ammonia is observed.

While it's always been speculated that Uranus is home to this noxious gas, the composition of its clouds has eluded scientists for decades. Leigh Fletcher conveyed it. Fletcher is the co-author and a recipient of the senior research fellowship at the University of Leicester.

"The superior capabilities of Gemini finally gave us that lucky break".

But due to the lack of oxygen and deathly cold temperatures, the smell isn't the worst problem for visitors."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", he added.
