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

Fate of James Webb Space Telescope murky [PDF]
Eos, Transactions American Geophysical Union, 2011 The James Webb Space Telescope (JWST), the next‐generation successor to the Hubble Space Telescope, was put on the chopping block by the U.S. House of Representatives Appropriations Subcommittee on Commerce, Justice, Science, and Related Agencies. The subcommittee approved a measure on 7 July that “terminates funding for [JWST], which is billions of ...

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 ...

Confirming Near- to Mid-infrared Photometrically Identified Obscured AGNs in the JWST Era
The Astrophysical JournalWe evaluate the underlying assumptions for the identification of active galactic nuclei (AGNs) through near- and mid-infrared photometry and spectral energy distribution (SED) fitting out to z ∼ 3.
