''This is the first time such detailed optical observations have been made on the day side of this exoplanet,'' a researcher said.
A planet orbiting a distant star has been discovered to have powerful iron winds whipping around its atmosphere.The planet, named WASP-76 b, is an ultrahot Jupiter with temperatures over 4,350 degrees Fahrenheit and is located about 640 light-years away from Earth.
spectrograph on the ESO's Very Large Telescope in Chile to examine the day-side atmosphere of WASP-76 b. There, researchers discovered a strange stream of iron atoms moving between the lower and upper layers of the planet's atmosphere.
, will further aid astronomers' understanding of WASP-76 b's climate and the properties of other ultrahot Jupiters across the galaxy.'' 's ability to make such precise measurements is crucial,'' study co-author Christophe Lovis, associate professor in the Astronomy Department at the UNIGE Faculty of Science, said in the statement. ''This level of precision allows us to explore the dynamic processes in the atmospheres of exoplanets like WASP-76 b with an unprecedented level of detail.
