A Search for Radio Technosignatures from Interstellar Object 3I/ATLAS with the Allen Telescope Array

Sofia Z. Sheikh, Valeria Garcia Lopez, Isabel Gerrard +12

In 2025 July, the third-ever interstellar object, 3I/ATLAS, was discovered on its ingress into the Solar System. Similar to the NASA Voyager missions sent in 1977, science probes b…

Vertical Temperature Structure in Io's Atmosphere from ALMA SO Observations

Timothy N. Proudkii, Katherine de Kleer, Imke de Pater +4

The structure of Io's atmosphere is controlled by competing processes, from volcanic outgassing and sublimation to radiative cooling and plasma heating. Yet, the lack of an observa…

Zonal winds in Titan's middle atmosphere from a stellar occultation observed with Keck adaptive optics

Theresa C. Marlin, Eliot F. Young, Katherine de Kleer +9

We present spatially resolved Keck/NIRC2 images of a stellar occultation by Titan on September 5, 2022 and compare them to predictions from concurrent ALMA observations and a suite…

Revealing Io's Surface using JWST-NIRISS Aperture Masking Interferometry and Neural Network Deconvolution

J. Sanchez-Bermudez, I. dePater, A. Conrad +6

Io is one of Jupiter's largest moons and the most volcanically active body in the Solar System. Its very active surface has hot spots produced by volcanic eruptions popping up at s…

A multi-frequency global view of Callisto's thermal properties from ALMA

Maria Camarca, Katherine de Kleer, Bryan Butler +5

We present thermal observations of Callisto's leading and trailing hemispheres obtained using the Atacama Large Millimeter/submillimeter Array (ALMA) at 0.87 mm (343 GHz), 1.3 mm (…

The Atmosphere of Titan in Late Northern Summer from JWST and Keck Observations

Conor A. Nixon, Bruno Bézard, Thomas Cornet +42

Saturn's moon Titan undergoes a long annual cycle of 29.45 Earth years. Titan's northern winter and spring were investigated in detail by the Cassini-Huygens spacecraft (2004-2017)…
