Using observations made with the James Webb Space Telescope (JWST), an international scientific team, in which the Instituto de Astrofísica de Canarias (IAC) participates, has confirmed variations in morning and evening atmosphere of the exoplanet WASP-39 b, about 700 light-years away from Earth. The research has revealed differences in temperature and atmospheric pressure, as well as indications of different cloudiness and winds that could reach thousands of miles per hour. The results are published in Nature. WASP-39 b, a giant planet with a diameter 1.3 times greater than Jupiter, but

The event at the IAC headquarters will take place on Monday 19 May, while the IACTEC will open its doors on Tuesday 20 May. Both days will be held in person, with two visiting hours

An international team, including a researcher from the Instituto de Astrofísica de Canarias (IAC), has obtained an incredible image of the planetary nebula NGC 1514 using the James Webb Space Telescope (JWST), revealing the nebula's spectacular dusty rings in unprecedented detail. NGC 1514 was one of the first nebulae to be studied by astronomer William Herschel, who noted that when viewed through his telescope (the biggest in the World at the time) the nebula looked like a fuzzy cloud somewhat similar in appearance to one of his other discoveries: the planet Neptune. The new images acquired
