Uranus, Planet, Galaxy

A study which was published in the journal Nature Astronomy, says that the planet Uranus upper atmosphere was surrounded by hydrogen sulfide, which gives rotten eggs smell. The presence of this gas in the atmosphere was a long debated topic, but the recent study has confirmed the presence of this gas in the atmosphere of the planet.

The study which was lead by author Patrick Irwin of Oxford University in England said: “If an unfortunate human were ever to descend through Uranus’ clouds, they would be met with very unpleasant and odiferous conditions.”

The previous observations which are done by the ground telescope and the Voyager 2 spacecraft are not cleared, and the composition of the Uranus atmosphere had remained in doubt. Scientists have wondered about the presence of the hydrogen sulfide or ammonia which had to dominate the ice giant’s cloud but that have not got any evidence about it. The data which was obtained from the Near-infrared Integral Field Spectrometer (NIFS) instrument present on the Gemini North telescope on Hawaii’s Mauna Kea summit.

The spectroscopic instrument measures the infrared light from the Uranus into its wavelengths, and the bands that are obtained in the spectrum is known as absorption lines. These lines absorb the infrared light that comes from the Sun, which helps the scientists to analyze the components of the Uranus atmosphere. The co-author Patrick Irwin who is from the University of Oxford said:”Now, thanks to improved hydrogen sulfide absorption-line data and the wonderful Gemini spectra, we have the fingerprint which caught the culprit.”

The clouds of the Neptune are also same as those of Uranus, and according to researchers the only difference between the clouds of the two planets is “ice giants,” and that of Jupiter and Saturn led to the trace to the World’s formation environments. When our solar system was formed, the balance between the nitrogen and Sulphur and ammonia and Uranus’s detected hydrogen sulfide was able to determine with the help of temperature and location of the planet’s formation.

As per Dr. Fletcher, a deck of clouds is formed by condensation and it locks away from the cloud-forming gas and gets hidden behind the levels that are not visible through our telescopes.  He added by saying “Only a tiny amount remains above the clouds as a saturated vapor… and this is why it is so challenging to capture the signatures of ammonia and hydrogen sulfide above cloud decks of Uranus.”
