Scientists find a terrestrial molecule in the atmosphere of a distant planet


Astronomers at Queen’s University Belfast first discovered a terrestrial particle in Atmosphere For a planet outside the solar system, it is a hydroxyl radical (OH), according to Universe Today, and this molecule is considered to exist on Earth, but scientists do not yet know how far it exists on Planets The other, new research shows that the molecule is present in hot Jupiter’s atmosphere, WASP-33b.

The planet is located 400 light years from the sun, and it is a gas giant closer to its star than Mercury to the sun, as it is heated to extreme temperatures: more than 2500 degrees Celsius, and this heating is able to melt most of the known minerals, but it also made the planet suitable for study .


The atmosphere of a distant planet

Scientists said that the chemicals in the atmosphere emit distinctive radiation in the temperature that can be easily recognized, they examined the planet with the Subaru telescope, and studies showed that the hydroxyl radicals are present in the planet’s atmosphere – a molecule of one oxygen atom and one hydrogen atom (the abbreviation of OH) ), It reacts with water vapor and carbon monoxide.

The authors of the scientific work noted that “this is the first direct evidence of OH in the atmosphere of an exoplanet”, and the hydroxyl radical is in the Earth’s atmosphere when water vapor interacts with oxygen, and it is possible that it forms on WASP-33b that the intense heat is detonated from the star vapor water.

The scientists said: “Each discovery in this area improves our understanding of the outer planets and the methods needed to study their atmospheres.”
