📢 #Webb reveals steamy atmosphere ♨️ of exoplanet WASP-96 b, capturing the distinct signature of water 💧 along with evidence for clouds & haze — the most detailed measurements of this kind to date. Read more here: esawebb.org/news/weic2206/ or below 👇 #WebbSeesFarther
WASP-96 b is a hot, puffy gas giant planet orbiting a distant Sun-like star. On 21 June, Webb’s #NIRISS measured light from the WASP-96 system for 6.4 hours as the planet moved across the star 👇
The result: a light curve— showing the overall starlight dimming during transit, when the planet blocks some starlight, and a transmission spectrum— made by comparing starlight filtered through a planet’s atmosphere to unfiltered starlight when the planet is beside the star 👇

📢 #Webb delivers deepest image of the Universe yet, looking far back in time when the Universe was less than a billion years old. The image is about the size of a grain of sand held at arm’s length, yet it reveals thousands of galaxies. Read more esawebb.org/news/weic2209/ or 👇
This is Webb’s First Deep Field, the deepest, sharpest infrared image of the distant Universe so far. It shows galaxy cluster SMACS 0723 as it appeared 4.6 billion years ago, with many more galaxies in front of and behind the cluster 👇
The combined mass of this galaxy cluster acts as a gravitational lens 🔎 magnifying more distant galaxies, including some seen when the Universe was less than a billion years old 👇
