Explore the solar system, trace stellar lifecycles, discover exoplanets, and investigate the large-scale structure of the universe.
Open PlanetariumStudy planetary orbits, compositions, atmospheres, moons, asteroids, comets, and the comparative planetology of our solar system.
Trace stellar evolution from nebula to main sequence, red giant, and final states. Use HR diagrams to classify stars by luminosity and temperature.
Explore galaxy types, the Milky Way structure, Hubble's law, dark matter, dark energy, the cosmic microwave background, and the Big Bang model.
Navigate the night sky, identify constellations, and track planets for any date and location.
Plot stars on the Hertzsprung-Russell diagram and trace evolutionary paths from birth to death.
Compare planetary data, explore surface features, and analyze atmospheric compositions across the solar system.
Model the expanding universe, calculate Hubble's constant, and explore the cosmic distance ladder.
Tracing a star from hydrogen cloud to white dwarf on the HR diagram made stellar evolution unforgettable.Dr. Mitchell, Astronomy
The planetarium mode is incredible — I can see exactly what's in the sky tonight from my location.Jake L., Grade 10
