CHEOPS’ Recent Analysis Shows Intriguing Details of Exoplanet WASP-189b

intriguing results

After eight months, ESA’s space telescope CHEOPS offered the first scientific data.CHEOPS’ mission is to find and examine exoplanets. It was developed as part of a partnership between the ESA and Switzerland, including more than a hundred engineers and scientists. 

Using data from CHEOPS, a team of scientists has succeeded recently in carrying out detailed research of the exoplanet WASP-189b, one of the most extreme bodies in the Universe. Here is what you need to know. 

WASP-189b’s Features Now Examined

WASP-189b is CHEOPS’ target and one of the most extreme planets in the Universe. It orbits the star HD 133112, known as the hottest stars, to own a planetary system. The WASP-189 system is estimated to be 322 light-years away, situated in the Libra constellation. 

According to Monika Lendl, the lead author of the research from the University of Geneva, WASP-189b is quite the planet. It is incredibly intriguing because it is a gas massive that orbits very close to its host star. It also takes less than 3 days for it to circle its star. 

“Based on the observations using CHEOPS, we estimate the temperature of WASP-189b to be 3,200 degrees Celsius,” said Lendl. 

Highly Accurate Brightness Measurements

Scientists couldn’t see WASP-189b because it is too far away and also close to its host star. The only solution was to rely on indirect techniques. And this was the perfect moment for CHEOPS.

The space telescope uses highly accurate brightness measurements. When a cosmic body passes in front of its star as seen from our planet, the star appears to be fainter for a short period. Such a thing is called a transit. Also, when a planet passes behind its star is called an occultation. 

Scientists examined several occultations of WASP-189b with the help of CHEOPS. The results are genuinely intriguing. It appears that WASP-189b doesn’t reflect a lot of starlight because it absorbs most of it, heating it and making it shine. 

Furthermore, scientists think that WASP-189b is not very reflective because no clouds are present on its dayside. 

More spectacular discoveries are now expected from the incredible CHEOPS!
