DARK SKY · EXPLORATION HUB
You’ve seen what light pollution takes away. Here’s what’s waiting on the other side of a dark sky — the objects that fill it, the worlds next door, and the machines we built to reach them.
01 / COSMIC OBJECTS
Zoom out from a single star to the largest structures that exist. Everything here is invisible from a Bortle 9 city — and ordinary from a dark sky.
TYPICAL SCALE · 1.4 MILLION KM
Colossal spheres of plasma, fusing hydrogen into starlight for billions of years.
TYPICAL SCALE · 100 LIGHT-YEARS
Vast clouds of gas and dust — the nurseries where new stars ignite.
EVENT HORIZON · UP TO BILLIONS OF KM
Gravity so extreme that not even light can climb back out.
TYPICAL SCALE · 100,000 LIGHT-YEARS
Islands of hundreds of billions of stars, turning slowly through the dark.
LARGEST SCALE · 100+ MILLION LIGHT-YEARS
On the grandest scale, galaxies string together into a glowing web of filaments.
02 / THE SOLAR SYSTEM
Eight worlds circling one ordinary star. Tap a planet to pull up its file — or just watch them run their orbits.
03 / THE SKY ITSELF
For thousands of years the constellations were humanity’s map, calendar and storybook. Pick one and watch it draw itself — then go find it outside.
04 / THE SPEED OF LIGHT
Light is the fastest thing that can exist — 299,792 km every second. Pick a destination and race it there. The Moon run happens in true real time.

05 / THE COSMIC CALENDAR
Squeeze the whole history of the universe into a single year. The Big Bang is January 1st. Drag across it — and notice how late we arrive.
JANUARY 1 · 00:00:00
Space, time, matter and energy all begin at once. The universe is a searing, formless fog.
