 ===== Description=====
-fill in your topical group description (brief) here.
+This topical group covers neutrino detection from all natural sources, including the Sun, the Earth, and astrophysical sources.  Specific topics include:
+** Early Universe **
+  * Cosmic neutrino background: prospects for detection
+  * Neutrino flavor composition and impact on the nucleosythesis
+  * Absolute neutrino mass: prospects for measuring it
+**Geoneutrinos **
+  * Flux and spectral measurements
+  * Separation of U/Th contributions, flux & mantle contributions
+  * Geographical spread
+**Solar**
+  * CNO: solar metallicity, solar model
+  * 8B spectral shape: sensitivity to NSI, matter effects, day/night
+  * Precision low-energy measurements (pp, pep): luminosity
+**Supernova**
+  * Prospects for DSNB measurement
+  * Galactic supernova: flavor composition, pointing, supernova mechanism, BSM physics
+  * Pre-supernova neutrinos
+**Atmospheric**
+  * Identifying prompt component
+  * Neutrino flavor conversion physics
+**Extragalactic**
+  * The origin of high energy neutrinos and the birthplace of cosmic rays
+  * The physics of cosmic accelerators: neutrino flavour, energy spectrum, and BSM
+  * Cosmogenic neutrinos: GZK neutrinos and cosmic ray composition
+  * Cross sections at high energies
