Christopher M0YNG is a radio amateur based in Gloucestershire whose personal site covers amateur radio, solar and battery tracking, self-hosted tech, and small computing projects like the Penkesu Tiny Computer. The site is notably available via Gopher, Gemini, and Tor in addition to HTTP, making it a fascinating example of smolnet philosophy in practice.
http://sunstarfrance.com/
Olly Penrice runs this site combining a French gite rental property called Les Granges with a serious passion for astrophotography in the dark skies of Provence. Visitors can browse astro imaging galleries, explore local cycling and climbing, and even book a stay at the gite to experience the region firsthand.
http://talkorigins.org/faqs/faq-solar.html
Written by Sverker Johansson, this detailed FAQ explores the science of solar neutrinos, nuclear fusion in the sun, helioseismology, and the famous solar neutrino problem with rigorous depth and extensive references. It also addresses creationist arguments about the sun, making it a uniquely thorough resource for both scientific education and skeptical inquiry.
