WISE/CatWISE Constraints On Dysonian Waste: A Mid-Infrared Scan for Galaxy-Scale Heat Signatures
Introduction: The Dysonian Search in the Mid-Infrared Dysonian SETI seeks indirect indicators of advanced civilizations by looking for large-scale astroengineering signatures, notably waste heat in the mid-infrared. This study leverages all-sky infrared data from WISE and CatWISE to probe galaxy-scale systems for anomalous, diffuse infrared emission that could signify large-scale energy usage. Starting from the…

Observing Spatial and Temporal Variations in the Atmospheric Chemistry of Rocky Exoplanets
Introduction: Why 4D Atmospheres Matter The next era of exoplanet science aims to move beyond single snapshot spectra and toward a dynamic picture of rocky worlds. By jointly studying spatial (across the planetary disk) and temporal (seasonal and short-term) variations in atmospheric chemistry, researchers hope to uncover weather patterns, photochemistry, and potential biosignatures that could…

Observing Spatial and Temporal Variations in Rocky Exoplanet Atmospheres with LIFE
Introduction: The quest to map exoplanet atmospheres in four dimensions As astronomers push the boundaries of observing nearby rocky exoplanets, the goal is no longer just to detect atmospheric components. The emerging field seeks to characterize how atmospheric chemistry varies across a planet’s surface and over time. Mid-infrared observations promise a window into 4D (three…

Observing Spatial and Temporal Variations in Rocky Exoplanet Atmospheres: Prospects for LIFE-era Insights
Introduction: Why 4D Atmospheric Chemistry Matters As telescopes edge closer to characterizing rocky exoplanets beyond our solar system, the ability to observe not just a planet’s composition but how its atmosphere changes in space and time becomes increasingly essential. Spatial and temporal variations in atmospheric chemistry offer a window into climate dynamics, surface–atmosphere exchange, and…
