How to use this skill

1. Start with modules/research-checklist.md and capture up-to-date sources.
2. Review modules/known-gaps.md and resolve outstanding items.
3. Route questions through the specialist modules listed in _toc.md to surface mission-specific findings.
4. When presenting results, cite the relevant source tags (e.g., [Euclid-ESA-2025]) from the research checklist.

Module overview

• Core guidance — operational playbook for selecting the right topic module.
• Known gaps — outstanding research questions and pending updates.
• Research checklist — workflow + source log.
• Twelve topical modules covering solar physics, planetary systems, exoplanets, stellar evolution, galaxies, cosmology, dark sector, multi-messenger observations, instrumentation, and data logistics.

Research status

• Source log populated with ESA, ESO, LIGO, and JWST mission resources (accessed 2025-11-09).
• Modules include the latest public results from Solar Orbiter, Euclid, JWST, CHEOPS, LIGO-Virgo-KAGRA O4, and ESO VLT surveys.
• Future refresh triggers: Euclid Year-1 cosmology release, Parker Solar Probe final perihelion analysis, GWTC-5 publication, JWST Cycle-4 exoplanet results.***
