The First Weak-lensing Analysis with the James Webb Space Telescope: SMACS J0723.3–7327

The Astrophysical Journal, 2023
Utilizing the James Webb Space Telescope Early Release NIRCam Observations, we perform a weak-lensing analysis of the massive galaxy cluster SMACS J0723.3–7327 ( z = 0.39).

Modeling Wind‐Driven Waves on Other Planets: Applications to Mars, Titan, and Exoplanets

Journal of Geophysical Research: Planets, Volume 131, Issue 4, April 2026.
Abstract Waves could exist on any planet with sustained winds and stable surface liquids. However, differences in atmospheres, liquids, and gravity confound efforts to extend Earth‐based empirical wave models to other planetary environments. We adapted a physics‐based numerical wave model to study how planetary conditions affect the growth of waves. We

Steady Collapse of Uranus' Exosphere After 1998 to the Present Decade

Geophysical Research Letters, Volume 53, Issue 6, 28 March 2026.
Abstract Uranus' thermospheric temperature decreased from ∼800K in 1986 to ∼450K in 2022 as determined from observations of H3+ and H2 infrared emissions. Spitzer 2007 lower atmosphere observations do not emulate this cooling trend. Here we show that the atomic H Lyman ⍺ emission from the disk of Uranus observed by HST from 2011 to 2022 are not ...

Short‐Term Variability of Jupiter's Satellite Footprints as Spotted by JWST

Geophysical Research Letters, Volume 53, Issue 5, 16 March 2026.
Abstract We present the main Alfvén wing (MAW) spots of Io and Europa as observed by the Near‐Infrared Spectrograph onboard the James Webb Space Telescope. These auroral footprint features have been measured previously, but only in emission. Here, the derived ionospheric H3+ ${\mathrm{H}}_{3}^{+}$ emission, temperature and column density are reported ...

The James Webb Space Telescope: Mission Overview and Status [PDF]

AIAA SPACE 2012 Conference & Exposition, 2011
The James Webb Space Telescope (JWST) is the scientific successor to the Hubble Space Telescope. It is a cryogenic infrared space observatory with a 25 m2 aperture (6 m class) telescope that will achieve diffraction limited angular resolution at a wavelength of 2 µm.

Accelerated Knowledge Discovery: A Vision for NASA Science

Earth and Space Science, Volume 13, Issue 3, March 2026.
Abstract This paper introduces the sixth paradigm of scientific discovery: accelerated knowledge discovery (AKD). This paradigm is defined by the full integration of artificial intelligence (AI) into the research workflow as a tool augmenting cognitive capabilities of human scientists.

JWST/NIRSpec Reveals the Atmospheric Driver of Saturn's Variable Magnetospheric Rotation Rate

Journal of Geophysical Research: Space Physics, Volume 131, Issue 3, March 2026.
Abstract Past measurements of Saturn's upper atmosphere have allowed only a broad scale view of the temperature and ion density structures within the auroral region. However, Saturn's auroral currents include a planetary period current component that is produced by neutral atmospheric flows.
