A distant planet known for its bad weather smells like rotten eggs, according to a new study.

Scientists, according to the BBC, studied the atmosphere of HD 189733 b, which has hot temperatures and precipitation that looks like falling glasses, using data from the James Webb Space Telescope.

Hydrogen sulfide, which also exists on Jupiter, makes up most of HD 189733b’s atmosphere and gives off a strong stench, according to the researchers. The same gas is emitted during farts.

These are the first times that hydrogen sulfide has been detected on a planet outside our solar system.

“Well, if your nose could work at 1000C… the atmosphere would smell like rotten eggssaid Dr. Guangwei Fu, an astrophysicist at Johns Hopkins who led the research.

The study was published in the journal Nature.

Although hydrogen sulfide is one of the gases that indicate that distant planets may host alien life, researchers are not looking for life on this planet because it is a stinky gas giant, like Jupiter.

However, they say finding hydrogen sulfide here is a step toward understanding how planets form.

The James Webb Telescope is helping to analyze the chemicals on distant planets, thus leading astronomers to learn more about their origins.

“It has changed the game quite a bit. It is truly a revolution in the field of astronomy. It has delivered the capability we promised and even exceeded our expectations in certain wayssaid Dr. Fu.

The researcher plans to use information from the space telescope to study more planets.
