We Even the most difficult of neighbours can be difficult. Earth.

Now Scientists discovered that the planet closest to our own smells of rotten egg.

The Scientists at the Johns Hopkins University In the meantime, USThe atmosphere of HD 189733b, a suggests that it is a planet. JupiterHydrogen sulfide is present in trace amounts.

HD 189733 B is an Exoplanet. It is outside of our Solar System.

The The discovery of hydrogen-sulphide in the atmosphere of the exoplanet provides scientists with new clues on how sulphur – a planet’s building block – might affect the interior and atmosphere of exoplanets.

At Only 64 light years away EarthHD 189733b is nearest “hot Jupiter” Astronomers are able to observe the passing of a star in front of it.

The Planet also has temperatures as high as 927C, and is well-known for its violent weather. This includes glass raining down on the sideways winds of 5,000mph.

Guangwei FuAstrophysicists are able to observe the universe from a new perspective. Johns Hopkins University, said: “Hydrogen sulphide is a major molecule that we didn’t know was there.

“We It’s exactly what we predicted. JupiterWe had detected it in the solar systems, but not outside.

“We’re not looking for life on this planet because it’s way too hot, but finding hydrogen sulphide is a stepping stone for finding this molecule on other planets and gaining more understanding of how different types of planets form.”

The The planet was discovered in 2005 and has since been an important part of the study of exoplanet atmospheres.

The The new data comes from the James Webb Space Telescope The journal was published on the date of publication Nature. The The research has also ruled methane out of HD 189733b.

“We had been thinking this planet was too hot to have high concentrations of methane, and now we know that it doesn’t,” Mr Fu said.

The Researchers hope to track more exoplanets, and determine the high levels of sulphur that might influence their formation near their star parent.
