StarWatch is a weekly astronomy column produced by Moravian College covering night sky events, star maps, moon phases, and detailed guides to constellations and celestial phenomena visible from the Lehigh Valley region. Written by Dr. Terry Pundiak, each installment combines accessible storytelling with genuine astronomical depth, covering topics from the imaging of the M87 black hole to the mechanics of Easter dating and the effects of precession on telescope alignment.
https://grace.umd.edu/~tlaloc/archastro
The official web presence of the Center for Archaeoastronomy, a professional research organization founded at the University of Maryland in 1978, dedicated to the interdisciplinary study of astronomy in ancient and indigenous cultures. Visitors can explore peer-reviewed publications, newsletters, essays on ethnoastronomy, and learn about ISAAC, the international society promoting archaeoastronomy worldwide.
http://hnsky.org/
Home of ASTAP and HNSKY, two free astronomy programs offering image stacking, plate solving, and a full-featured planetarium for amateur astronomers and astrophotographers. The creator also shares their own astrophotography images and equipment details, making this a practical hub for both software users and sky enthusiasts.
http://learningastronomy.com/
LearningAstronomy.com appears to be an educational resource focused on astronomy, though the page content is extremely sparse with only a single image loaded. The domain name strongly suggests a site aimed at introducing beginners to astronomy concepts and space science.
http://chebucto.ns.ca/~aa063
Mike Boschat's astronomy page celebrates 60 years of stargazing from Halifax, Nova Scotia, covering lunar, solar, meteor, and noctilucent cloud observations with an impressive collection of Soviet-made telescopes and binoculars. The site includes astro images, SOHO discoveries, links to clear sky clocks, light pollution maps, and a vast collection of astronomy resources alongside the author's work with the Aeronet Sunphotometer at Dalhousie University.
https://costajulio.tripod.com//cv/astronomy.htm
Julio Costa shares his lifelong passion for amateur stargazing, recounting memorable early encounters with telescopes and the purchase of a Celestron 8-inch Schmidt-Cassegrain reflector. The page includes personal photos of the moon and Jupiter with its moons, accompanied by warm, humorous writing about the joys and quirks of backyard astronomy.
https://astro.uni-bonn.de/~pbrosche/astoria.html
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.

Jordi Gallego's deep sky astrophotography site showcases stunning images captured since 2008 from his private Fosca Nit Observatory in Àger, Spain, one of southern Europe's darkest sky locations. The site combines aesthetic long-integration imaging with technical depth, including full equipment and processing notes per image, plus a dedicated section for exoplanet transit photometry observations.
https://radiojove.gsfc.nasa.gov/
NASA's Radio JOVE Project invites students, educators, and citizen scientists to observe and study solar and planetary radio emissions using affordable dipole antenna telescope kits they build themselves. The site offers detailed guides for constructing radio telescopes, downloadable spectrograph software, a data archive, educational materials, and a community map of active Radio JOVE teams around the world.
https://background.uchicago.edu/~whu
Wayne Hu is a Professor of Astronomy and Astrophysics at the University of Chicago, and this site serves as his academic hub covering cosmology research including CMB polarization, baryon acoustic oscillations, cosmic shear, and large-scale structure. Visitors will find an impressive collection of tutorials, lecture notes, research codes, publications, and course materials spanning decades of work in theoretical cosmology.
