The Universe — What Is Out There?
10 min
▼
The universe is everything that exists — every star, planet, galaxy, and even the space in between. It is
93 billion light-years across (that we can observe!) and contains at least
2 trillion galaxies. But how did it all begin? And what is most of it made of?
This module introduces the scale of the cosmos and the Big Bang theory — the leading scientific explanation for how the universe was born.
▶ VIDEO
The Big Bang — Kurzgesagt
A beautifully animated explanation of how the universe began from an incredibly hot, dense point around 13.8 billion years ago, and expanded to everything we see today.
A mind-bending look at the scale of the observable universe — from the Earth, to the solar system, to the Milky Way, to the cosmic web of galaxies beyond.
⚡ Mind-Bending Fact: The light you see from the Andromeda Galaxy left its source
2.5 million years ago — before humans even existed. When you look up at the night sky,
you are looking back in time!
Zoom from the smallest quantum particles all the way to the full observable universe. A classic interactive that puts cosmic scale into perspective. Scroll to zoom in and out!
Our solar system formed about 4.6 billion years ago from a cloud of gas and dust.
At its centre is the Sun — a star so massive that it contains 99.86% of all the mass
in the solar system. Orbiting it are 8 planets, dozens of moons, asteroids, comets, and dwarf planets.
Let's take a tour!

The Solar System — Our Home in Space (Kurzgesagt)
A beautifully illustrated tour of every major body in our solar system — from the scorching surface of Mercury to the icy Kuiper Belt beyond Neptune, with stunning scale comparisons.
A stunning real-time 3D model of the solar system. Drag to rotate, click any planet to learn about it, and see the actual positions of planets today. Works in your browser — no download needed.
Since the first satellite launched in 1957, humans have sent spacecraft across the entire solar system,
walked on the Moon, lived on a space station, and landed robots on Mars. Space exploration is one of
humanity's greatest adventures — and it is still going! Let's look at the most remarkable missions and the
brave astronauts who made history.

The History of Space Exploration | A Short Documentary
From Sputnik to the Space Shuttle to the Mars rovers, this documentary covers decades of space exploration and the technology that made it possible.
What Life Inside The International Space Station is Like
Ever wondered how astronauts sleep, eat, or use the bathroom in zero gravity? This video gives a fascinating behind-the-scenes look at life aboard the International Space Station.
🏆 Hall of Fame Missions: Sputnik 1 (1957) — First satellite ever launched, by the Soviet Union. Apollo 11 (1969) — Neil Armstrong & Buzz Aldrin became the first humans on the Moon. Voyager 1 (1977) — Still travelling; now the most distant human-made object, in interstellar space. Hubble Space Telescope (1990) — Transformed our view of the universe with iconic deep-field images. Perseverance Rover (2021) — NASA's rover searching for signs of ancient life on Mars.
ASTRONAUT LEGENDS
Yuri Gagarin
First human in space (April 12, 1961), completing one orbit of Earth in 108 minutes
Neil Armstrong
First human to walk on the Moon, July 20, 1969 — "One small step for man…"
Valentina Tereshkova
First woman in space (1963); orbited Earth 48 times over three days
Sally Ride
First American woman in space (1983); flew on Space Shuttle Challenger
Chris Hadfield
Commander of ISS; famous for playing guitar in space and inspiring millions online
Fly alongside real NASA spacecraft using actual mission data. You can replay historic missions like Voyager and New Horizons, or watch the Perseverance rover on Mars right now.
The universe is full of objects so extreme they seem impossible. Black holes that swallow light.
Nebulae the size of thousands of solar systems, glowing in spectacular colours. Comets streaking
across the sky. Neutron stars spinning hundreds of times per second. This module takes you on a
tour of the most jaw-dropping phenomena in the cosmos.
▶ VIDEO
Black Holes Explained — Kurzgesagt
What is a black hole? How do they form? What happens if you fall into one? Kurzgesagt's iconic animated explainer answers all of this in a way that will blow your mind (but hopefully not the rest of you).
Comets, Asteroids, and Meteors — What They Are & How They Differ
What is the difference between a comet, an asteroid, and a meteor? Where do they come from? This clear video explains each one and why scientists study them so carefully.
🌠 Amazing Space Objects: Black Hole: A region where gravity is so extreme that not even light can escape. The first black hole ever photographed (M87*, 2019) is 6.5 billion times the mass of our Sun.
Nebula: A vast cloud of gas and dust in space — often the birthplace of new stars. The Pillars of Creation nebula is 6,500 light-years away.
Neutron Star: The collapsed core of a dead massive star, just 20 km wide but with more mass than our Sun. A teaspoon would weigh a billion tonnes!
Comet: A ball of ice and rock that develops a glowing tail as it approaches the Sun — the tail always points away from the Sun, blown by solar wind.

10 Beautiful Nebulae in the Milky Way
A visual showcase of the most breathtaking nebulae in our galaxy — stellar nurseries, supernova remnants, and planetary nebulae captured in vivid colour.
Browse the most iconic images ever taken by the Hubble Space Telescope — galaxies, nebulae, supernovae, and deep fields — with explanations written for curious learners.

Stars, Galaxies & the Future of Space
12 min
▼
The Sun is just one of about 200–400 billion stars in our Milky Way galaxy, and
the Milky Way is one of at least 2 trillion galaxies in the universe. Stars are not forever —
they are born, live for millions or billions of years, and die, sometimes in spectacular explosions.
This module covers how stars work, what galaxies are, and what the future of space exploration looks like.
▶ VIDEO
The Life Cycle of a Star — TED-Ed
From a collapsing cloud of gas to a glowing main-sequence star, to a red giant, and finally a white dwarf or supernova — this video explains every stage of a star's life beautifully.
A fascinating look at the long-term future of the cosmos — the death of stars, the fate of black holes, and the ultimate end of the universe, trillions of years from now.
🔭 Future Missions to Watch: Artemis Programme (NASA): Plans to return humans to the Moon and eventually send astronauts to Mars.
James Webb Space Telescope (2021–): The most powerful space telescope ever built; already revealing galaxies from less than 300 million years after the Big Bang.
Mars Sample Return: A joint NASA/ESA mission to bring rock samples from Mars back to Earth for detailed analysis.
STAR LIFE CYCLE
Nebula
A cloud of gas and dust pulled together by gravity — the birth cloud of stars
Protostar
A young star forming as the cloud contracts and heats up at its core
Main Sequence
The long stable phase; our Sun has been in this phase for 4.6 billion years
Red Giant
As hydrogen runs out, the core contracts and outer layers expand enormously
Supernova / White Dwarf
Massive stars explode as supernovae; smaller stars like our Sun become white dwarfs
