NASA Watch is a long-running independent watchdog site run by Keith Cowing, covering NASA news, policy, personnel changes, and space exploration with a critical insider perspective. With archives stretching back to 1993, it tracks everything from Artemis and ISS developments to congressional oversight and agency politics.
http://bo.astro.it/~biblio/atlas/atlas-in.htm
Hosted by the Library of the Department of Astronomy in Bologna, this scholarly site guides visitors through a curated collection of historic celestial atlases spanning the 16th through 18th centuries, from Piccolomini's Renaissance star maps to Bode's Uranographia. Created by Davide Neri, a philosopher and physicist, it beautifully bridges the history of science and art through some of the most celebrated astronomical cartography ever published.
https://cosmotography.com/index.html
Cosmotography is the astrophotography showcase of R. Jay Gabany, a 2010 AAS Chambliss Amateur Achievement Award recipient who captures stunning CCD images of galaxies, nebulae, star clusters, and more using high-end telescopes across multiple observatories worldwide. The gallery features meticulously processed multi-exposure color images taken through remotely controlled observatories in California, Kitt Peak Arizona, and Melbourne Australia, making it a remarkable window into deep-sky imaging at the amateur-professional frontier.
http://stargazing.net/david/constel/skymapindex.html
David Haworth's stargazing site offers a comprehensive index of printable sky maps organized by month, time, and observing location, with five detail levels ranging from basic star fields to full constellation boundaries. Each map links to more detailed constellation charts, making this a practical reference for amateur astronomers heading out for a night of naked-eye or telescopic observing.
https://britastro.org/useful-links
The British Astronomical Association, supporting amateur astronomers since 1890, maintains this curated directory of useful links covering UK astronomy societies, observing resources, and related organizations. Visitors will find connections to groups like the Society for Popular Astronomy, the Federation of Astronomical Societies, and many more resources spanning the full breadth of amateur astronomy.
http://sten.astronomycafe.net/the-astronomy-cafe
NASA scientist-educator Sten Odenwald has maintained this astronomy education hub for over 20 years, filling it with popular essays on cosmology, black holes, space travel, and the weird corners of nature. Visitors will find Q&A resources, blog posts on recent space discoveries, and details on his published books including a photo-filled history of space exploration through 100 iconic objects.
http://atlasoftheuniverse.com/
Created by Richard Powell, this stunning educational site presents nine nested maps of the universe, each roughly ten times the scale of the previous, zooming out from the nearest stars to the entire visible universe 14 billion light years away. Multilingual and richly illustrated, it offers a rare sense of cosmic scale that makes abstract astronomical distances genuinely comprehensible.
http://aoas.org/
AOAS (Amateur Observers' Astronomical Society) is a club website for astronomy enthusiasts, likely featuring meeting information, observing events, and resources for stargazers. The domain and structure suggest a regional astronomy club serving members interested in telescopes, sky-watching, and community observing sessions.
http://astronomy.net/
Astronomy.Net is a comprehensive hub for amateur and professional astronomers alike, offering articles, forums, constellation guides, sky event calendars, and equipment classifieds all in one place. Built and maintained by John Huggins since 1994, the site covers everything from telescope optics and astrophotography to meteor showers and planetary conjunctions.
