Using JWST's near-infrared imaging, researchers directly imaged 29 Cygni b and found it metal-rich with an orbit aligned to its star, consistent with formation in a protoplanetary disk via rapid accretion; at about 15 Jupiter masses it’s a planet, not a star.
Using JWST imaging of 29 Cygni b, a ~15-Jupiter-mass exoplanet about 133 light-years away, researchers find the planet is unusually metal-rich and its orbit aligns with its star, suggesting it may have formed in a protoplanetary disk via bottom-up accretion rather than simple direct collapse. This links the formation of some of the Milky Way’s most massive planets to the same disk-based processes that birth smaller worlds.
