9 narrated journeys through real space, about fifteen minutes each. Put it on the projector, press Start, and Aetherion flies your class there with captions and built-in discussion stops. No microphone, accounts or installs needed.
The Grand Tour and Eyes in Orbit are free for everyone. The other lessons, their full guides and every new lesson come with a teacher license.
Grades 4-8About 15 minutes11 stops4 discussion stops
A tour of the Sun, all eight planets, the Moon and Pluto, drawn where they really are today.
Students fly to each world in turn and hear what it is made of, how hot or cold it is, and what missions have found there. Four discussion stops ask them to compare worlds and explain why Earth is livable.
Grades 4-8About 15 minutes8 stops3 discussion stops
Day and night, seasons, Moon phases, eclipses and tides, explained by three bodies in motion.
Students watch Earth spin and tilt, fly to the Moon to see where it came from and why it has phases, return to Earth for tides, line up the Sun for eclipses, and stand on the Moon to feel its gravity.
Grades 4-9About 15 minutes8 stops3 discussion stops
What an orbit really is, and the space stations, telescopes and satellites that use one.
Students start with Newton's cannonball idea, then visit the ISS, Tiangong, Hubble, the Moon, the James Webb Space Telescope and missions that watch the Sun, and finish with satellites they use every day.
Grades 4-9About 15 minutes9 stops2 discussion stops
From Apollo to Artemis: how people first reached the Moon, why going back is hard, and what comes next.
Students review Apollo and Apollo 13, learn why the Moon is harder to reach than the space station, meet the Artemis rocket and capsule, follow the 2026 Artemis II crew around the Moon, and explore the Moon's south pole, its dangers, and future missions.
Grades 6-12About 15 minutes10 stops3 discussion stops
The nearest stars, how we measure their distance, and the planets that might be habitable.
Students learn the light-year, visit Alpha Centauri, Proxima and its planet, Barnard's Star, Sirius, Vega and Polaris, then explore the seven-planet TRAPPIST-1 system and the Earth-like Kepler-452 b.
Grades 6-12About 15 minutes10 stops2 discussion stops
The life story of a star, from a glowing nebula to a white dwarf, neutron star or black hole.
Students visit a stellar nursery, the Pillars of Creation, a young cluster, the Sun, a blue supergiant, a red giant, a white dwarf, a dying supergiant and a supernova remnant, then learn that their own atoms were made in stars.
Grades 6-12About 15 minutes9 stops2 discussion stops
The shape, size and history of the Milky Way, and how we mapped a galaxy we can never leave.
Students start at the Sun and follow its 230-million-year orbit, visit star clusters and the spiral arms, pull back to see the whole disk, dive to the black hole at the center, meet neighbor galaxies, and finish with how to see the Milky Way themselves.
Grades 7-12About 15 minutes8 stops2 discussion stops
What black holes really are, and four different ways astronomers detect objects that give off no light.
Students visit Cygnus X-1, the nearby Gaia black holes, the center of the Milky Way, Andromeda, M87 and the giant quasar TON 618, learning about escape velocity, event horizons, the first black hole images and gravitational waves.
Grades 6-12About 15 minutes11 stops2 discussion stops
A step-by-step zoom from Earth to the edge of the observable universe, and the tools that measure it.
Students pull back from Earth to the Moon, the solar system, the nearest stars, the Milky Way, neighboring galaxies, galaxy clusters, the cosmic web and finally the edge of the observable universe, using light travel time as a ruler.
