The Okie-Tex Star Party is an annual astronomy event held at Camp Billy Joe in the Black Mesa area of Oklahoma, offering some of the darkest skies in the Southwest for stargazers. The site covers everything attendees need, including registration, event schedules, observing lists, meal menus, accommodation info, and a photo gallery from past gatherings.
https://astronomy-links.net/SETI_Battleship.html
Clark M. Thomas offers a witty essay examining the movie Battleship through the lens of real SETI science, exploring the plausibility and implications of contact with extraterrestrial civilizations. The piece weaves together astronomy, pop culture criticism, and philosophical musings about what our radio and TV signals might reveal to any alien observers.
http://celestrak.org/
CelesTrak, maintained by T.S. Kelso, is a premier resource for satellite tracking data including NORAD GP element sets, two-line element (TLE) files, and orbital environment tools used by the global space community. Now operating as a 501(c)(3) non-profit, it offers visualization tools, SOCRATES conjunction analysis, documentation, and special event coverage including debris events and rocket body reentries.
http://uacnj.org/
The United Astronomy Clubs of New Jersey (UACNJ) operates multiple observatories at Jenny Jump State Forest and hosts regular public stargazing nights, meteor shower events, and astronomy programs for all ages. The site serves as a hub for member clubs, event scheduling, live sky cameras, newsletter archives, and donation drives for new observatory construction.
http://maps.seds.org/Const/const_family.html
Hosted on the SEDS (Students for the Exploration and Development of Space) server, this reference page catalogs the traditional constellation families of the night sky, grouping constellations like the Ursa Major family, the Zodiac, and the La Caille southern sky instruments. Each constellation entry links to deeper information, making it a useful guide for amateur stargazers learning to navigate the celestial sphere.

Xavier Jubier's interactive Google Map documents the path and details of the June 30, 1973 total solar eclipse over Mauritania, offering a precise geographic visualization of this historical celestial event. The map-based format makes it easy to explore the eclipse's path of totality across the region with geographic context.
https://las-skycamp.org/
The LAS Equinox Sky Camp is the UK's largest star party, bringing hundreds of amateur astronomers together for a week of dark-sky observing at Kelling Heath Holiday Park on the North Norfolk coast. The site covers event logistics, pitch booking advice, vendor trade stands, talks, and links to associated astronomy societies and suppliers.
http://ned.ipac.caltech.edu/help/cosmology_calc.html
Hosted by NASA's Extragalactic Database (NED) at Caltech, this curated page collects links to online cosmology calculators contributed by researchers at UCLA, University of Colorado, and other institutions. Visitors can compute distances, lookback times, Hubble parameters, K-corrections, and other key cosmological quantities by entering values like redshift, Hubble constant, and Omega parameters.
http://xjubier.free.fr/en/site_pages/solar_eclipses/TSE_1970_GoogleMapFull.html
Xavier Jubier's interactive Google Map traces the path of the March 7, 1970 total solar eclipse across the USA and Mexico, offering a precise geographic visualization of the event's totality corridor. Part of a larger solar eclipse resource site, this page combines historical astronomical data with modern mapping tools to help enthusiasts and researchers explore eclipse paths.
https://nrao.edu/pr/2000/vla20/background
A commemorative background page from the National Radio Astronomy Observatory celebrating the VLA radio telescope's first twenty years of scientific discovery, covering breakthroughs from Mercury's icy poles to gravitational lenses and gamma ray bursts. Packed with links to research highlights, aerial photos, visitor information, and introductory radio astronomy materials, it serves as both a historical record and an educational gateway to one of the world's most powerful telescopes.
