Hosted at the University of Bonn's Argelander Institute for Astronomy, this long-running site by Wolfgang R. Dick serves as a curated hub for the history of astronomy, linking to resources on history of science, notable events like the Simon Marius symposium, and the Working Group for the History of Astronomy. Created in 1995 and maintained for decades, it bridges academic astronomy with historical scholarship in both English and German.

The companion website to Michael A. Covington's book 'Astrophotography for the Amateur,' published by Cambridge University Press, covering film astrophotography, CCD imaging, and image processing. Visitors can browse a picture gallery of Covington's own astrophotos, download free astrophotography software, and find corrections and updates to the book.

Bartosz Ciechanowski's deep-dive interactive article on the Moon covers everything from its orbital mechanics and phases to tides, eclipses, craters, and gravitational effects, all brought to life with stunning real-time 3D simulations and draggable visualizations. One of the most richly illustrated and technically impressive science explainers on the web, it invites readers to genuinely experience lunar concepts rather than just read about them.

Al Kelly's dedicated astrophotography site showcases stunning CCD images of galaxies, nebulae, star clusters, and solar system objects captured with equipment including a Celestron CGE 1400 telescope and Orion Parsec 8300C camera. Beyond the image galleries, the site offers a CCD instruction manual, a G2V color calibration article, and links to fellow astrophotographers, making it a valuable resource for amateur astronomers interested in CCD imaging.

https://mm4rk3t.neocities.org/
A minimalist personal page from a creator known as mm4rk3t, built around a Latin aphorism about stars being visible only at night and the sleepless nights that make mathematicians and astronomers. The sparse, cryptic aesthetic and classical quotation give the site an enigmatic, philosophical quality that hints at interests in astronomy and mathematics.

Astro Publishing offers a free multilingual astronomy magazine available to read and download in full, with a mission to bring astronomy culture to the widest possible audience. All issues can be accessed directly from the site, which is notable for its strict no-tracking, no-cookie privacy policy.
https://theastronomycafe.net/
An archived recreation of Dr. Sten Odenwald's legendary 'Astronomy Cafe' website from circa 2001, once a destination where a professional astronomer answered thousands of public questions about space, the universe, and infrared astronomy. The site preserves a nostalgic snapshot of early web science outreach, featuring Dr. Odenwald's books, his 'Ask the Astronomer' feature, and philosophical explorations of concepts like 'nothing' and the Big Bang.
