James Webb Space Telescope

JWST observations of 29 Cygni b point to disk accretion, with carbon- and oxygen-rich signatures and a spin-aligned orbit that argue against star-like collapse.

JWST observations of super-Earth L 98-59 d reveal a sulfur-dominated atmosphere sustained by a perpetual magma ocean, a combination that fits no existing planetary category and may define a new class of exoplanet.

NASA's James Webb Space Telescope has captured the most detailed images yet of nebula PMR 1, nicknamed the Exposed Cranium, revealing a two-light-year-wide structure shaped by jets from a massive dying star roughly 5,000 light-years away in the constellation Vela.

James Webb Space Telescope identifies galaxy COSMOS2020-635829 at redshift z=1.156, the most distant jellyfish galaxy known, revealing cluster environments were stripping galaxies far earlier than models predicted.
