Uranus smells like rotten eggs – proven by astronomers
Source:
The Seventh planet from the Sun is full of secrets and , opening which, you can learn a lot about the origin of our Solar system. An international team of researchers closer to solving these mysteries, but they had to figure out what Uranus has one of the most unpleasant smells known to man.
In a press release from the Gemini Observatory reported that with the help of a powerful telescope, located on top of a Hawaiian volcano, in the cloud tops of Uranus, is discovered hydrogen sulfide. The smell of gas people are, as a rule, avoid, associating it with rotten eggs. High concentrations of hydrogen sulfide can be hazardous to health and human life. The gas concentration of several hundred ppm can literally kill a person in 30 minutes.
It turns Out that if there were ever to visit the surface of Uranus, it will be welcomed not just odor, but also strangulation. In addition, given the extremely low temperature of -200 degrees Celsius, unpleasant consequences will begin long before people smell.
Researchers have long suspected that the atmosphere of Uranus, the concentration of hydrogen sulfide is much higher than in the atmosphere of Saturn and Jupiter. However, the low temperature caused by the distance of the planet from the Sun, freezes gas. Crystals can form gas clouds, but the spectrometer is much more difficult to cope with studying hard and heavy crystals.
Previously, the spacecraft Voyager 2, the only reach of the planet, which is called «ice giants», trying to figure out what chemical substances are contained in the clouds of Uranus. Unfortunately, in 1986 it was able to provide accurate data. Today the Observatory of dzhemini, there are tools that allow you to examine gases in the clouds of distant planets. Their discovery is able to turn all ideas about the evolution of the Solar system.
The study of the exact composition of distant planets will help to determine where in the Solar system they were first formed and how they move after its occurrence. It is known that Uranium, like other planets, was formed from a giant disk of gas and dust, bathed in the sun about 4.6 billion years ago. According to Glenn Orton, a scientist from the laboratory of NASA, the new discovery suggests that at an early stage of formation of the Solar system occurred some «shake», which was the cause of migration of the planets.
The Composition of the heavenly bodies is a fundamental parameter in determining its formation and evolutionary history. It is known that Uranus and Neptune could not be "gas giants" like Jupiter and Saturn. Instead, they became "". The reason is that the disk of dust and gas is more widely dispersed from the Sun, and with a smaller amount of available materials to Uranus and Neptune took longer to form. Slower the time, the party gave the Sun more time for the withdrawal of helium and hydrogen from the Solar system before Uranus and Neptune were able to capture these elements of their gravity. After some time we will be able to learn even more.
