COSMOS
a journey through the space between stars
Leaving Earth's Orbit
Every journey begins with a single point of light. We drift past the blue marble, out into the dark, where silence has a texture of its own.
Wandering Past Mars
Dust storms the size of continents rage below. From here, it's just a rust-colored ember, spinning quietly in the void.
Into the Asteroid Belt
Rock and ice tumble in slow motion around us. Somewhere ahead, a gas giant waits, wrapped in bands of amber light.
The Nebula Awakens
Light bends. Color blooms where there should be nothing. This is where stars are born — and where some go to die.
Where Light Cannot Escape
Space itself begins to fold. Watch the stars behind it bend and blur — this is a black hole, gravity so complete that nothing, not even light, ever leaves.

Our Galaxy, From Outside
Everything so far — every star we passed, every planet — was a grain of sand on one arm of this spiral. 100,000 light-years across, 100 to 400 billion stars, and we've only ever left one of them.
Galaxies Are the Small Things Now
Pull back further and even galaxies become points of light — strung together in filaments hundreds of millions of light-years long, wrapped around vast, dark voids. This is the largest structure in existence.
The Observable Universe Ends Here
This faint, mottled glow is the Cosmic Microwave Background — the oldest light we can ever see, from 13.8 billion years ago. Beyond it isn't empty. It's just further than light has had time to reach us. This is the edge of everything we can observe.
Beyond the Horizon
You've flown from a single planet to the edge of the observable universe. One final light awaits — bright, patient, and infinite.
