Jakarta, CNBC Indonesia – Astronomers find a planet that is said to have a very hot atmosphere. It was reported that WASP-189b’s atmosphere reached 3200 degrees Celsius during the day.
This planet is called uninhabitable. WASP-189b is a member of a subset of exoplanets: hot Jupiter.
The study on WASP-189b is the first for scientists to investigate different layers of the atmosphere. Namely with the composition and chemical characteristics of each.
These extreme worlds are gas giants, like Jupiter, but orbit very close to the induction star. The planet revolves around its Sun in less than 10 days.
WASP-189b is 322 light years away and is 1.6 times the size of Jupiter. “We measured the light coming from the planet’s parent star and passing through the planet’s atmosphere,” said astronomer from Lund University, Bibiana Prinoth, quoted from Science Alert, Wednesday (2/2/2022).
“The gases in its atmosphere absorb some of the starlight, similar to ozone which absorbs some of the sunlight in Earth’s atmosphere and thus leaves its characteristic fingerprint. With the help of HARPS (High Accuracy Radial Velocity Planet Searcher abord ESO’s La Silla Observatory) we were able to identify the substance appropriate”.
For these gases heavy metal vapors such as hot Jupiter. WAS-189b’s atmosphere also contains gas clouds of iron, titanium, chromium, magnesium, vanadium and manganese.
The researchers also found traces of titanium oxide, which has never been detected in an exoplanet’s atmosphere before. Titanium oxide is rarely found in nature on Earth, but on the planet its presence can help form the atmosphere.
“Titanium oxide absorbs short-wave radiation, such as ultraviolet radiation. Its detection can show layers in WASP-189b’s atmosphere interacting with stellar irradiation similar to how the ozone layer on Earth does,” said University of Bern astrophysicist Kevin Heng.
