JWST directly imaged 29 Cygni b, a 15-Jupiter-mass object near the planet-star boundary.
Its mass suggests a star-like classification, but detected heavier elements point toward planetary formation.
The object highlights why formation history may matter more than mass alone.

TOI-5205b is a roughly Jupiter-mass planet orbiting a low-mass M-dwarf every 1.6 days.
Its size and host-star mass strain standard disk-scaling expectations in planet formation theory.
Researchers are now studying similar systems with JWST through the GEMS program.

JWST observed the W51 star-forming region about 17,000 light-years from Earth.
The telescope revealed young stars and structures hidden by dust in optical views.
Comparisons with ALMA show that some starbirth activity remains obscured even to JWST.

JWST found unusual sulfur-rich atmospheric chemistry on exoplanet L 98-59 d, 35 light-years away
The planet likely contains a deep magma ocean that traps sulfur compounds under extreme pressure, lowering its detectable density
The discovery suggests sulfur worlds may be a common but previously unrecognized class of planet

First-ever 3D map of Uranus's upper atmosphere created using JWST's NIRSpec instrument
Uranus's magnetic field is tilted 59 degrees from its rotation axis — the strangest in the solar system
Auroral patterns sweep across the planet in complex, shifting configurations unlike Earth's stable rings
Upper atmosphere has continued cooling over 30 years, now averaging 426 kelvins
15-hour continuous observation tracked faint molecular emissions up to 5,000 km above the clouds
