SpaceEngine is a virtual universe simulator for computers. Users can travel from star to star and galaxy to galaxy, landing on planets, moons and asteroids, and can alter the speed of time. Real celestial objects appear alongside procedurally generated regions based on scientific knowledge.
SunCalc is an online application for showing the movement of the sun and sunlight phases for a selected day and place. It displays sunrise, sunset, shadow length, solar eclipse, sun position and elevation on an interactive map, and includes reverse calculation and photovoltaic data.
Celestia is a free space simulator that provides real-time 3D visualization of space. It displays objects and orbits based on scientific data and runs on Windows, Linux, macOS, iOS and Android. Users can travel through the solar system, to over 100,000 stars, or beyond the galaxy. Its catalogues are expandable with add-ons, and users can create their own objects and planetary systems.

Encyclopedia Astronautica is a space history resource covering rockets, spacecraft, launch vehicles, astronauts, cosmonauts, spaceflights, engines and space exploration. The site provides an alphabetical index and space history chronology and calendar pages.
Ringwatchers is an educational resource for documentaries, courses, books, reference material, or self-learning.
