The James Webb Space Telescope (JWST) has started a revolution in exoplanetary science. From studying in exquisite detail the chemical inventories and physical processes in gas giant exoplanets, the structure and chemical diversity of the enigmatic sub-Neptune population to even providing constraints on the atmospheric make-up of rocky exoplanets, the observatory is enabling cutting-edge science that is touching virtually every sub-area in the field. In this review Chapter, we showcase key highlights from exoplanet science being conducted with this state-of-the-art space observatory, which we believe is representative of the transformational science it is producing. One of the key takeaways from these pioneering JWST observations is how they are starting to reshape not only how we think, study and interpret exoplanet observations -- but how they are also reshaping our intuition about our very own Solar System planets.

  1. Detection of CO, H$_2$O, and OH in WASP-18b with JWST/NIRISS using Direct-Extracted Spectra and Cross-Correlation

    astro-ph.EP 2026-05 unverdicted novelty 6.0 of 10

    Direct pixel-level extraction of NIRISS spectra for WASP-18b followed by cross-correlation yields 4.4σ CO, 3.4σ H2O, and 7.8σ OH detections, with improved abundance constraints from subsequent retrievals.

  2. JWST Observations of Asteroid 2024 YR4 Rule Out a 2032 Lunar Impact and Demonstrate a New Regime for Planetary Defense Follow-up

    astro-ph.EP 2026-05 conditional novelty 6.0 of 10

    JWST/NIRCam observations of 2024 YR4 extend the orbital arc by eight months, reduce 2032 lunar encounter uncertainty by >30x, and rule out impact with a 22,900 ± 800 km miss distance.

  3. HAT-P-70b through the Eyes of MAROON-X: Constraining Elemental Abundances of Metals and Insights on Atmosphere Dynamics

    astro-ph.EP 2026-05 conditional novelty 6.0 of 10

    New MAROON-X observations of HAT-P-70b detect multiple neutral and ionized metals with day-to-night wind signatures and demonstrate that ionization-aware retrievals yield abundance ratios closer to solar values except...

  4. J0404+1112: A 3-Hour Eclipsing White Dwarf-Brown Dwarf Probing Multiple Atmospheric Regimes

    astro-ph.SR 2026-06 unverdicted novelty 5.0 of 10

    J0404+1112 is a 2.93 hr period totally eclipsing WD+BD system with a hot DA white dwarf (T_eff ~28,000 K) and ~40 M_Jup brown dwarf, enabling isolation of nightside emission and serving as a JWST atmospheric benchmark.
