The Meteorite Market has been one of the web's oldest meteorite dealers since 1995, offering over 100 scientifically significant varieties including Martian, Lunar, Pallasite, and Carbonaceous Chondrite specimens with detailed photos and pricing. Visitors can browse an extensive alphabetical catalog while learning about meteorite types through dozens of informational pages, making it both a shopping destination and an educational resource for collectors and enthusiasts alike.
http://pasnola.org/
The Pontchartrain Astronomy Society, established in 1959, is a non-professional astronomy club serving Southeast Louisiana with events, observing sites, forums, and newsletters. Members gather to discuss celestial objects, attend star parties, and access resources like Clear Sky Charts and ISS sighting schedules for the New Orleans area.
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://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.
http://astrochemistry.eu/
Astrochemistry.eu, maintained by Guido W. Fuchs, serves as a collaborative hub for researchers in astrophysics and astrochemistry, covering observational, laboratory, and theoretical investigations of interstellar chemistry. Visitors can find featured news on prize-winning discoveries, upcoming conferences, job opportunities, and curated links to major databases, journals, and research networks worldwide.
http://telescope.livjm.ac.uk/
The official homepage of the Liverpool Telescope, a 2.0 metre fully robotic observatory on the Canary Island of La Palma, owned and operated by Liverpool John Moores University. Visitors can find technical guidance on applying for observing time, access data archives, browse recent astronomical discoveries, and follow live telescope status updates.
https://rochesterskies.org/
The Rochester Astronomy Club is a 501(c)(3) non-profit based in Rochester, Minnesota, offering public night sky viewing events, member resources, and a club forum for amateur astronomers. The site features observing reports, event calendars, member blogs covering topics like Titan shadow transits and comet sightings, and outreach activities at local community events.
http://russsscope.net/staxtutorial.htm
A beginner-focused step-by-step tutorial for stacking and processing planetary images using the free software Registax, written by an astrophotographer who uses a Meade DSI Color camera. The guide walks through alignment, optimization, stacking, and wavelet sharpening in plain language, making it accessible to newcomers who find other tutorials too vague.
https://occultations.org/
The International Occultation Timing Association (IOTA) is a volunteer scientific organization founded in 1983 that coordinates amateur astronomers in timing astronomical occultations, including stars being blocked by asteroids and the Moon. The site offers observing guides, equipment recommendations, occultation predictions, citizen science campaigns, and published data that has contributed to real discoveries such as new double stars and improved asteroid shape models.
