American Association of Variable Star Observers (AAVSO)
An international nonprofit organization that trains and supports amateur and student astronomers in observing and reporting variable star brightness data used in real astrophysics research. AAVSO offers free beginner tutorials (including a no-equipment-needed 10-Star Tutorial), webinars, mentorship, and community forums for students starting in observational astrophysics.

International Astronomical Search Collaboration (IASC)
A free citizen-science program in which student teams analyze real telescope imaging data using Astrometrica software to search for and report new asteroids. Month-long campaigns run several times a year and student discoveries can result in official credit and provisional asteroid designations.
Planet Hunters TESS (Zooniverse)
A free online citizen-science project where volunteers examine light-curve data from NASA's Transiting Exoplanet Survey Satellite (TESS) to help identify signals of possible exoplanets. Participant identifications have contributed to real peer-reviewed exoplanet discoveries, and an educator guide supports classroom or independent use.
Las Cumbres Observatory – 100 Global High School Teams
A Las Cumbres Observatory education program that gives high school student teams free access to LCO's global network of 0.4-meter robotic telescopes to observe galaxies, nebulae, and star clusters, with online training in astronomical data-analysis tools such as SalsaJ and TopCAT.
Pulsar Science Collaboratory (NANOGrav)
An out-of-school-time citizen-science research program in which students age 13 and up receive training and then analyze real radio-astronomy data from the Green Bank and Arecibo-affiliated telescopes to search for new pulsars; several student participants have been credited as co-discoverers of real pulsars.
Exoplanet Watch (NASA)
A NASA citizen-science project in which volunteers, including complete beginners, observe exoplanet transits with their own telescope or request free archival/robotic-telescope data, analyze the resulting light curves with NASA's free EXOTIC software, and submit results to a shared scientific database.
Galaxy Zoo (Zooniverse)
A Zooniverse citizen-science project, active since 2018, in which volunteers classify the shapes of distant galaxies from telescope images, including new imagery from the Vera C. Rubin Observatory, to help astronomers study how galaxies form and evolve.
