NASA’s Webb Investigates Eternal Sunrises, Sunsets on Distant World - NASA Science

Near-infrared spectral analysis of terminator confirms differences in morning and evening atmosphere Researchers using NASA’s James Webb Space Telescope have finally confirmed what models have previously predicted: An exoplanet has differences between its eternal morning and eternal evening atmosphere. WASP-39 b, a giant planet with a diameter 1.3 times greater than Jupiter, but similar mass […]

Sulphur Makes A Surprise Appearance in this Exoplanet's Atmosphere

At our current level of knowledge, many exoplanet findings take us by surprise. The only atmospheric chemistry we can see with clarity is Earth’s, and we still have many unanswered questions about how our planet and its atmosphere developed. With Earth as our primary reference point, many things about exoplanet atmospheres seem puzzling in comparison … Continue reading "Sulphur Makes A Surprise Appearance in this Exoplanet’s Atmosphere"

MPS: Ein maßgenauer Blick auf Exoplaneten

Aus den Helligkeitsschwankungen seines Muttersterns lassen sich die Größe und andere Eigenschaften eines Exoplaneten bestimmen. Um Fehler zu vermeiden, ist das Magnetfeld des Sterns entscheidend. Eine Pressemitteilung des Max-Planck-Instituts für Sonnensystemforschung.

For your Friday night commute/weekend reading, I wrote an article for @[email protected] about our JWST #WASP39b chemical inventory, what it tells us, and why it's so important https://theconversation.com/james-webb-space-telescope-uncovers-chemical-secrets-of-distant-world-paving-the-way-for-studying-earth-like-planets-195224
James Webb space telescope uncovers chemical secrets of distant world – paving the way for studying Earth-like planets

The James Webb space telescope is making the headlines again – this time completing its first chemical inventory of a distant, exotic world.

The Conversation
Patchy #clouds and #photochemistry on #WASP39b. Very exciting data from the #JWST telescope. https://www.nature.com/articles/d41586-022-03820-3
First active chemistry on an exoplanet revealed by Webb telescope

Ground-breaking observations reveal clouds, chemical reactions and more on a world outside our Solar System.
