A star system located 900 light years away attracts a planet the size of Jupiter that emits heavy metal gases into the atmosphere, where the host star attraction changes. shape to look like "football".
While planets of this size do not release heavy metals, the WASP-121b is located near its star at a "dangerous" distance, warming it enough to release gases.
"Heavy metals have been observed on another hot planet, but only in the lower atmosphere, and with WASP-121b, magnesium and iron gas can be detected from far away from the planet," says David Singh of the world. Johns Hopkins University in Baltimore.
In a new study published in the journal Astronomical, researchers badyzed the observations of the Hubble Space Telescope and discovered that the UV stars of the host star were helping magnesium and iron to escape from the upper atmosphere, which could make the conditions warmer.
The researchers say the planet looks like "football" because of its proximity to the host star. The observations indicate that the temperature of the upper atmosphere reaches 4600 degrees Fahrenheit.
This burning environment, combined with other features, makes the planet a good place to look for things like magnesium and iron.
NASA said conditions are a key target of the James Webb Space Telescope, in which the planet's atmosphere could be home to carbon dioxide, which appears at longer wavelengths.
The study of WASP-121b can reveal how planets lose their primordial atmosphere.
