The planet HD 189733 b, 63 light-years away, fascinates scientists with its pungent atmosphere and extreme weather, which reveal the secrets of planetary formation.
They are colorful and shrouded in mystery. The distant planets in space hide many surprises. Some of them have attracted people since time immemorial. For example, Mars is one of the most studied planets ever, as it is similar to Earth in many aspects and could be a candidate for human colonization in the future. Jupiter, which has several fascinating properties, is similarly interesting for scientists. Its atmosphere is made up largely of hydrogen and helium and is much denser than Earth’s atmosphere. The planet also has dynamic weather with extreme winds and storms that have been going on for hundreds of years. Its clouds are made up of ammonia, water and hydrogen sulphide.
While scientists have collected a lot of information about nearby planets, planets tens of light years away from Earth are still largely unknown to them. Most recently, scientists reported on new knowledge about the planet HD 189733 b, which orbits the star HD 189733, located in the constellation of the Fox approximately 63 light years from Earth. This Jupiter-like planet orbits very close to its parent star, resulting in extremely high temperatures on its surface. According to a new study, this planet also has its own typical smell, or rather smell. It smells like rotten eggs.
Most of the atmosphere of this planet is hydrogen sulfide, which is also found on Jupiter. According to scientists, this is one of the first discoveries of hydrogen sulfide on exoplanets, i.e. planets outside our solar system. This gas would normally indicate that the planet might be home to life, but the high temperatures virtually rule out any life. Temperatures around a thousand degrees Celsius are too high for even the most primitive life. Still, scientists say the discovery of hydrogen sulfide is another piece of the puzzle in understanding how planets form.
