The James Webb Space Telescope observed the exoplanet WASP-121b, also known as Tylos, for nearly 37 hours, revealing the first-ever continuous observation of atmospheric escape with two enormous helium tails stretching over half its orbit, providing new insights into planetary evolution and atmospheric dynamics.
NASA's James Webb Space Telescope has studied the extreme exoplanet WASP-121b, revealing its fiery origins, atmospheric composition, and the presence of molecules like silicon monoxide and methane, which provide insights into its formation and evolution in a harsh, close-in orbit around a hot star.
NASA's James Webb Space Telescope has detected silicon monoxide in the atmosphere of the ultrahot exoplanet WASP-121b, marking the first such discovery and revealing complex atmospheric dynamics, including unexpected methane presence on the planet's cooler nightside, due to vertical mixing and extreme temperatures.
Scientists using JWST discovered vaporized rock molecules in the atmosphere of the exoplanet Tylos (WASP-121b), revealing insights into its formation from dust and pebbles, and uncovering unexpected atmospheric processes like vertical methane mixing, which challenge current models of hot Jupiter evolution.
Scientists using the JWST have studied the ultra-hot exoplanet WASP-121b, discovering water, carbon monoxide, silicon monoxide, and methane in its atmosphere, providing insights into its formation involving space pebbles and rocky bombardments, and marking the first detection of SiO in a planetary atmosphere.
The European Space Agency (ESA) has captured images of "massive cyclones" on the exoplanet WASP-121 b, also known as Tylos, using a NASA/ESA telescope. The visuals were created by combining observations from 2016, 2018, and 2019, showcasing the dynamic atmosphere of this hot Jupiter, which has extreme temperatures over 3,000 Kelvins. The cyclones are thought to be caused by the temperature differences between the planet's dark side and its star-facing side.
The Hubble Space Telescope has observed extreme weather conditions on the hot Jupiter exoplanet WASP-121b, located 880 light-years away. The planet experiences intense cyclones and storms due to the significant temperature difference between its permanent day and night sides, with its atmosphere containing evaporated metals like iron and vanadium. These observations, combined with computer modeling, provide insights into the atmospheric dynamics of such exoplanets and could inform future studies of weather on smaller, potentially habitable worlds.
NASA's Hubble Space Telescope has provided astronomers with a unique data set by observing the exoplanet WASP-121 b, also known as Tylos, over the years 2016, 2018, and 2019. These observations revealed that the exoplanet's atmosphere changes over time, with evidence of dynamic weather patterns such as massive cyclones. The close proximity of WASP-121 b to its host star results in extreme temperatures and phenomena like iron rain on the night side. The study, which combines observational data with computational modeling, marks a significant step in understanding weather on exoplanets and could aid in the search for habitable worlds.
