Webb reveals an exoplanet atmosphere as never seen before

Science & Exploration 11/24/2022 637 views 26 likes The NASA/ESA/CSA James Webb Space Telescope just scored another first: a molecular and chemical portrait of a distant world’s skies. While Webb and other space telescopes, including the NASA/ESA Hubble Space Telescope, have previously revealed isolated components of this heated planet’s atmosphere, the new readings provide a … Read more

If Earth Were an Exoplanet, it Would Still be Tricky to Figure Out if There’s Life Here

How would Earth appear to alien astronomers? What would their observations tell them about Earth if they were searching the heavens for signs of habitability like we are? It’s a fun thought experiment. But the experiment is more than just fun: it’s scientifically instructive. In many ways, it’s easier to study our planet and how … Read more

First exoplanet image from James Webb Space Telescope revealed

Unsubtracted and KLIP subtracted image stamps for the NIRCam F356W (top row) and MIRI F1140C (bottom row) filters. The leftmost column displays the median unsubtracted image for a single science roll, and all other columns display the KLIP subtracted images for ADI, RDI, and ADI+RDI subtraction methods using the maximum number of KLIP PCA modes. … Read more

Webb detects carbon dioxide in exoplanet atmosphere

Science & Exploration 25/08/2022 3 views 0 likes The NASA/ESA/CSA James Webb Space Telescope has found definitive evidence for carbon dioxide in the atmosphere of a gas giant planet orbiting a Sun-like star 700 light-years away. The result provides important insights into the composition and formation of the planet, and is indicative of Webb’s ability … Read more

What the James Webb Space Telescope images mean for Canada’s exoplanet research

Among the first science images from the deep-space James Webb Space Telescope was an incredible Canadian feat, finding water molecules in the exoplanet WASP-96 b. The Canadian Space Agency (CSA) funded Near-Infrared Imager and Slitless Spectrograph (NIRISS) found water molecules in the exoplanet WASP-96 b. While the planet is a large world not habitable to … Read more

The Closeby Habitable Exoplanet Survey (CHES) Could Detect Exoplanets Within a few Dozen Light-Years of Earth Using Astrometry

As of this article’s writing, NASA has indicated that 5,030 extrasolar planets have been confirmed in 3,772 systems, with another 8,974 candidates awaiting confirmation. With next-generation instruments like the James Webb Space Telescope (JWST) coming online, the number and diversity of confirmed exoplanets are expected to grow exponentially. In particular, astronomers anticipate that the number … Read more
