How JWST Reads Exoplanet Air: Transmission and Emission Spectroscopy Compared
The James Webb Space Telescope employs transmission and emission spectroscopy to analyze exoplanet atmospheres, revealing their composition, temperature, and weather patterns. These complementary techniques are crucial for understanding alien worlds and advancing the search for life beyond Earth.
Astronomers propose telescope swarm to detect alien life
On April 16, researchers announced a 'three sigma' detection of dimethyl sulfide (DMS) in the atmosphere of exoplanet K2-18b, using data from the James Webb Space Telescope (JWST), implying a less tha
Models predict JWST will detect exoplanets with diesel smog
Imagine a world half the mass of Jupiter, orbiting a dim K-dwarf star, its atmosphere thick with the same sooty hydrocarbons found in diesel exhaust on Earth.
JWST spots cloud cycles on exoplanets with new method
On the distant exoplanet WASP-94A b, astronomers using the James Webb Space Telescope (JWST) have observed magnesium silicate clouds forming in the morning and completely dissipating by evening, revea
JWST Detects Methane in Atmosphere of Temperate Exoplanet TOI-199b
On a world the size of Saturn, bathed in a balmy 79 degrees Celsius, the James Webb Space Telescope has pierced the veil of exoplanet TOI-199b, pinpointing methane, a fundamental organic molecule.
