This remarkable finding has revealed an atmosphere that is unlike any other previously encountered.<\/p>\n<p>In a pioneering achievement, an international team of astronomers has created a 3D map of the atmosphere of the exoplanet WASP-121b, also known as Tylos. Utilizing the European Southern Observatory&#8217;s Very Large Telescope, the team identified complex weather patterns and a surprising chemical composition. Their <a href=\"https:\/\/www.nature.com\/articles\/s41586-025-08664-1\" rel=\"nofollow noopener\" target=\"_blank\">study<\/a>, published in an early unedited version on Tuesday in the journal <em>Nature<\/em>, paves the way for future research into extraterrestrial atmospheres.<\/p>\n<p>\u201cThe atmosphere of this planet exhibits behavior that challenges our current understanding of how weather systems function, not just on Earth, but on all planets. It&#8217;s reminiscent of something out of science fiction,\u201d Julia Victoria Seidel, a physicist at the European Southern Observatory (ESO) in Chile and lead author of the study, said in an ESO <a href=\"https:\/\/www.eso.org\/public\/news\/eso2504\/\" rel=\"nofollow noopener\" target=\"_blank\">statement<\/a>. It&#8217;s worth noting that, since the official definition of \u201cplanet\u201d remains limited to celestial bodies within our solar system (<a href=\"https:\/\/gizmodo.com\/planet-definition-exoplanets-sorry-pluto-2000469745#:~:text=Their%20definition%20of%20a%20planet,massive%20than%2013%20Jupiter%20masses\" rel=\"nofollow noopener\" target=\"_blank\">some astronomers are proposing to change this<\/a>), Tylos is technically an exoplanet\u2014but astronomers sometimes refer to it as a \u201cplanet\u201d for simplicity.<\/p>\n<aside class=\"pullquote text-center\">\u201cThis experience makes me feel like we\u2019re on the verge of uncovering incredible things we can only dream about now.\u201d<\/aside>\n<p>The exoplanet in question is a <a href=\"https:\/\/science.nasa.gov\/exoplanets\/gas-giant\/\" rel=\"nofollow noopener\" target=\"_blank\">gas giant<\/a> (a large planet primarily composed of helium and\/or hydrogen) roughly 900 light years away from Earth. It closely orbits its star in just around 30 hours\u2014so close, in fact, that Tylos is also classified as an <a href=\"https:\/\/www.sciencenews.org\/article\/hot-jupiter-orbit-sun-close-gravity-star-planet\" rel=\"nofollow noopener\" target=\"_blank\">ultra-hot Jupiter<\/a>: an extremely large and hot planet with a very tight orbit. The time it takes Tylos to complete one orbit is the same time it takes the gas giant to complete one rotation, meaning that one of Tylos\u2019 sides permanently faces its star and is much hotter than the other (i.e. it\u2019s tidally locked).<\/p>\n<p>Seidel and her colleagues analyzed the exoplanet\u2019s atmosphere using all four telescope units of the ESO\u2019s VLT. By tracing iron, sodium, and hydrogen, they were able to investigate the planet\u2019s distinct deep, mid, and upper atmospheric layers.<\/p>\n<p>\u201cThe VLT enabled us to probe three different layers of the exoplanet\u2019s atmosphere in one fell swoop,\u201d said Leonardo A. dos Santos, an assistant astronomer at the Space Telescope Science Institute in Baltimore who participated in the study. \u201cIt\u2019s the kind of observation that is very challenging to do with space telescopes, highlighting the importance of ground-based observations of exoplanets,\u201d he added.<\/p>\n<figure id=\"attachment_2000566057\" aria-describedby=\"caption-attachment-2000566057\" class=\"wp-caption alignnone\"><img fetchpriority=\"high\" decoding=\"async\" class=\"size-full wp-image-2000566057\" src=\"https:\/\/gizmodo.com\/app\/uploads\/2025\/02\/Tylos-chemical-atmosphere.jpg\" alt=\"Structure And Motion Of The Atmosphere Of The Exoplanet Tylos\" width=\"1280\" height=\"870\" srcset=\"https:\/\/gizmodo.com\/app\/uploads\/2025\/02\/Tylos-chemical-atmosphere.jpg 1280w, https:\/\/gizmodo.com\/app\/uploads\/2025\/02\/Tylos-chemical-atmosphere-300x204.jpg 300w, https:\/\/gizmodo.com\/app\/uploads\/2025\/02\/Tylos-chemical-atmosphere-1024x696.jpg 1024w, https:\/\/gizmodo.com\/app\/uploads\/2025\/02\/Tylos-chemical-atmosphere-768x522.jpg 768w, https:\/\/gizmodo.com\/app\/uploads\/2025\/02\/Tylos-chemical-atmosphere-680x462.jpg 680w, https:\/\/gizmodo.com\/app\/uploads\/2025\/02\/Tylos-chemical-atmosphere-896x609.jpg 896w\" sizes=\"(max-width: 1023px) calc(100vw - 2rem), (max-width: 1279px) calc(100vw - 26rem), 680px\"\/><figcaption id=\"caption-attachment-2000566057\" class=\"wp-caption-text\">The structure and movement of Tylos\u2019 atmosphere. \u00a9 European Southern Observatory<\/figcaption><\/figure>\n<p>The team then created a 3D map of their observations, unveiling an alien atmosphere outside of our Solar System in unprecedented detail.<\/p>\n<p>\u201cWhat we found was surprising: a jet stream rotates material around the planet\u2019s equator, while a separate flow at lower levels of the atmosphere moves gas from the hot side to the cooler side. This kind of climate has never been seen before on any planet,\u201d Seidel explained. In comparison to the size and speed of Tylos\u2019 jet stream, \u201ceven the strongest hurricanes in the Solar System seem calm in comparison,\u201d she added.<\/p>\n<p>Additionally, a companion <a href=\"https:\/\/www.aanda.org\/articles\/aa\/full_html\/2025\/02\/aa52405-24\/aa52405-24.html\" rel=\"nofollow noopener\" target=\"_blank\">study<\/a>\u2014published earlier this week in the journal <em>Astronomy &amp; Astrophysics<\/em> by some of the same researchers\u2014notes the discovery of titanium below the jet stream.
