History is an educational resource for learning science, history, language, geography, or general knowledge.
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.
An X account of Gunter Krebs, who identifies himself as a spaceflight historian and analyst, physicist and editor of Gunter's Space Page. The profile states he is also reachable on Mastodon.
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.
Official NASA X account for the Webb space telescope. The account states the telescope launched on Dec. 25, 2021, and that its first images were revealed on July 12, 2022.
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.
