Evidence for a Nonzero Eccentricity Superpuff Exoplanet WASP-107 b Using JWST Occultation Observation

The Astrophysical Journal Letters
WASP-107 b is an extremely low-density superpuff exoplanet whose inflated radius and evidence of strong internal heating make it a key target for understanding planetary structure and evolution.

Probing Ganymede’s Atmosphere with HST Lyα Images in Transit of Jupiter

The Planetary Science Journal, 2023
We report results from far-ultraviolet observations by the Hubble Space Telescope of Jupiter’s largest moon, Ganymede, transiting across the planet’s dayside hemisphere.

Hubble Space Telescope imaging of Eta Carinae [PDF]

The Astronomical Journal, 1991
We present new high spatial resolution observations of the material around η Carinae obtained with the Hubble Space Telescope Wide Field/Planetary Camera. The star η Carinae is one of the most massive and luminous stars in our Galaxy, and has been episodically expelling significant quantities of gas over the last few centuries.

Generative AI's Impacts on the Environment: What Can Critical Humanities Scholarship Offer Sociological Inquiry?

Sociology Compass, Volume 20, Issue 5, May 2026.
ABSTRACT In recent years, there has been a rapid and massive expansion of generative artificial intelligence (AI) technologies and infrastructures. Big AI Tech corporations are vigorously marketing these services in the pursuit of profit, despite their devastating impacts on the environment.

Radio Pulse Power Distribution of Lightning in Jupiter's 2021–2022 Stealth Superstorms

AGU Advances, Volume 7, Issue 2, April 2026.
Abstract Surveys and observations of lightning on Jupiter prior to the NASA Juno mission used night‐side imaging approaches, and a common conclusion was that the optical energy was similar to the highest energy terrestrial lightning flashes, or superbolts.

Characterization of the Outer Uranian Rings in the Visual and Near‐IR Using Keck, JWST, and HST Observations

Journal of Geophysical Research: Planets, Volume 131, Issue 4, April 2026.
Abstract We present observations of the Uranian outer ring system at near‐infrared and visible wavelengths. Observations with the Keck Telescope were taken in July‐August 2007 at 2.12 and 1.63 μm, when the ring plane was almost edge‐on (ring opening angle B=0.62 $B=0.62$–0.24° ${}^{\circ}$). These data showed, for the first time, the μ ring at infrared

Spatial and Energy Dependence of Energetic Electron Precipitation Originating From Jupiter's Inner and Middle Magnetosphere

Journal of Geophysical Research: Space Physics, Volume 131, Issue 4, April 2026.
Abstract Energetic electron precipitation transfers trapped magnetospheric energy into Jupiter's atmosphere, yet its contribution beyond the main auroral oval has to be fully quantified. This study statistically investigates the atmospheric energy input from electrons in the 30 keV–1.2 MeV range using in situ measurements from the Juno spacecraft ...

V659 Cen: System Members Updated

The Astronomical Journal
V659 Cen is a classical Cepheid which is part of a multiple system. Previous observations have shown that a hot companion dominates an ultraviolet spectrum and a cooler main-sequence star dominates an XMM-Newton spectrum. The Hubble Space Telescope Space

Motional Induction in Ganymede's Ocean

Geophysical Research Letters, Volume 53, Issue 6, 28 March 2026.
Abstract We investigate the magnetic signature of oceanic circulation in Ganymede's subsurface ocean using kinematic induction modeling. Our approach couples zonal jet flows from rotating thermal convection simulations with magnetic field models incorporating Ganymede's internal dynamo and external contributions from Jupiter.
