First JWST spectroscopy of GJ 504 b detects multiple molecules, retrieves atmospheric parameters including super-solar metallicity, and finds tentative support for planet-like formation.
Deep interferometric observations of a z≈1.12 barred spiral reveal bar-driven molecular inflows at a rate matching the galaxy's star formation rate of ~36 M⊙/yr.
Direct imaging reveals enhanced metallicity and aligned orbit in 29 Cyg b, supporting protoplanetary disk formation near the deuterium burning limit.
JWST difference imaging from COSMOS-Web and PRIMER has yielded 68 high-redshift supernovae including a core-collapse event at z>3 and a Type Ia at z>2, demonstrating the feasibility of wide-area time-domain searches in the early universe.
New JWST multi-filter imaging of Sgr B2 detects previously hidden massive stars and ionized structures while finding no extended young stellar objects, implying star formation there has only recently begun.
A denoising diffusion model trained on transformed JWST observations generates multi-band galaxy images that match key statistical properties of real galaxies for Roman weak lensing simulations.
LEGGOS presents a uniform framework that jointly models lensing, photometry, and integral-field spectroscopy to disentangle stellar populations in clumps of high-redshift lensed galaxies.
JWST color-magnitude criteria identify 467 dusty young objects in M33, NGC300, NGC7793 and NGC5068, with stable selection but up to 50% incompleteness at 5 Mpc and a practical limit of ~3 Mpc for individual MYSO studies.
Renaissance Simulations produce galaxies at z>10 whose stellar masses, star formation rates, sizes, and colors overlap with JWST observations while extending to lower masses.
JWST/MIRI imaging of Eps Ind A b prefers a double-PSF model likely due to systematics but demonstrates sensitivity to exomoons down to 1.3 M_Jup at separations >2 AU and 2.5 M_Jup at 0.52 AU.
