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

open access: yesAGU 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

open access: yesJournal 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

The Ambiguous Ecologies of Agri‐Alternatives: Exploring the Calculus of Social Reproduction in Rural India

open access: yesJournal of Agrarian Change, Volume 26, Issue 2, April 2026.
ABSTRACT This paper advances scholarship on agri‐alternatives by probing the gap between romanticised narratives of how alternative farming transitions ought to be and the actual practices farmers enact in their fields. Focusing on moments when such alternatives encounter on‐the‐ground realities, we propose ambiguous ecologies as a lens to explore the ...

CARGOISM AND SCIENTIFIC JUSTIFICATION IN THE SEARCH FOR EXTRATERRESTRIAL INTELLIGENCE

open access: yesZygon, 2019
This article compares justifications of the search for extraterrestrial intelligence (SETI) presented by scientists with ideational constructs associated with cargo cults in Melanesia. In focusing on similarities between cargoism and SETI, I argue that,
