Thanks astronomers at the center for astrophysics, harvard smithsonian have detected the first jupiter like planet without clouds or haze in its observable atmosphere. The findings were published this month in the astrophysical journal. Letters named wasp62b, the gas giant, was first detected in 2012 through the wide angle search for planets wasp south survey. Its atmosphere, however, had never been closely studied. Until now for my thesis i have been working on exoplanet characterization says: munaza lam a graduate student at the center for astrophysics who led the study. I take discovered planets and i follow up on them to characterize their atmospheres, known as a hot jupiter. Wasp 62b is 575 light years away and about half the mass of our solar system’s jupiter. However, unlike our jupiter, which takes nearly 12 years to orbit the sun, wasp 62b completes a rotation around its star in just four and a half days. This proximity to the star makes it extremely hot, hence the name: hot jupiter, using the hubble space telescope, a lam recorded data and observations of the planet using spectroscopy the study of electromagnetic radiation to help detect chemical elements, a lamb specifically monitored wasp 62b, as it swept In front of its host star three times, making visible light observations which can detect the presence of sodium and potassium in a planet’s atmosphere, ill admit that at first i wasn’t too excited about this planet a lamb says.

But once i started to take a look at the data i got excited while there was no evidence of potassium sodium’s presence was strikingly clear. The team was able to view the full sodium absorption lines in their data or its complete, fingerprint clouds or haze in the atmosphere would obscure the complete signature of sodium alam explains and astronomers, usually can only make out small hints of its presence. This is smoking gun evidence that we are seeing a clear atmosphere. She says cloud. Free planets are exceedingly rare. Astronomers estimate that less than seven percent of exoplanets have clear atmospheres. According to recent research, for example, the first and only other known exoplanet with a clear atmosphere, was discovered in 2018. named wasp 96b. It is classified as a hot saturn, astronomers believe studying exoplanets with cloudless atmospheres can lead to a better understanding of how they were formed. Their rarity suggests something else is going on or they formed in a different way than most planets. A lamb says, clear atmospheres also make it easier to study the chemical composition of planets, which can help identify what a planet is made of with the launch of the james webb space telescope later this year, the team hopes to have new opportunities to study and better Understand wasp 62b, the telescope’s improved technologies like higher resolution and better precision, should help them probe the atmosphere even closer to search for the presence of more elements such as silicon.
