Uranus, indeed, smells badly.

Researchers have found out what is in the composition of the planet's clouds at 2. 9 billion kilometers from the Sun. Researchers have confirmed that one of the key components of the clouds on Uranus is hydrogen sulfide, a gas with a strong odor that most people avoid. An international team of scientists came to this conclusion after using a spectrometer to disentangle infrared light from Uranus captured by the Gemini North telescope on Mauna Kea Island in Hawaii, informs diakaf. Data obtained with the Near-Infrared Integral Field Spectrometer (NIFS) was a sample of sunlight reflected from a region immediately above the main visible layer of clouds in Uranus' atmosphere. NASA has said that people should not be too concerned that the smell of hydrogen sulfide might overwhelm them, because if they ever get close enough to Uranus, choking and exposure to cold will do their effect far ahead of the smell in the atmosphere .

Detecting hydrogen sulphide in the clouds on Uranus and possibly on Neptune is a striking difference to the giant Jupiter and Saturn gaseous planets closer to the sun. Above the clouds of these planets, ammonia, a chemical compound formed from a nitrogen atom and three hydrogen but not hydrogen sulfide. This difference is a clue to the formation of the planets and their history. .
