exoplanets

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.

Webb telescope finds a Jupiter-sized planet orbiting a tiny red dwarf has fewer heavy elements in its atmosphere than its own star, defying all existing formation theories.

Using the upgraded GRAVITY+ instrument on the ESO's Very Large Telescope Interferometer, researchers have directly detected a second protoplanet forming in the disk around the young star WISPIT 2, located 437 light-years from Earth.

Two March discoveries reveal a 10-billion-year-old lava world with a thick atmosphere and a sulfur-dominated planet unlike anything in existing classification systems.

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.

A University of Washington team identifies signs of a catastrophic planetary collision around star Gaia20ehk, offering the first real-time analog of the giant impact that created Earth's Moon 4.5 billion years ago.
