The cosmos

Original artwork inspired by Voyager 1's 1990 Pale Blue Dot photograph: faint bands of scattered sunlight stretch across black space, and inside one of them sits a single tiny pale blue speck -- Earth.

Space is big, old, and strange -- and you are part of it.

  • Sunlight takes about 8 minutes and 20 seconds to reach Earth. When you see the Sun's glow, you are seeing the past.

  • Earth carries you around the Sun at about 67,000 miles per hour (107,000 km/h) -- and you cannot feel a thing.

  • On a dark night you can see the Andromeda Galaxy with your own eyes. Its light traveled about 2.5 million years to reach you.

  • Hubble's Ultra Deep Field image shows about 10,000 galaxies in a patch of sky roughly one-tenth the width of the full Moon.

  • Voyager 1, launched in 1977, is about to become the first human-made object one full light-day from Earth -- around November 18, 2026, roughly 16.1 billion miles away.

  • In 1990, Voyager 1 turned its camera back toward home. From billions of miles away, Earth appeared as a single pale blue dot.

Earth and life

Original artwork: thousands of starlings swirl together in a single shape-shifting cloud above tall reeds at sunset -- a murmuration.

Life on Earth is more inventive than any story we could make up.

  • There are about 3 trillion trees on Earth -- more than the estimated 100 to 400 billion stars in the Milky Way.

  • Arctic terns fly from the Arctic to Antarctica and back every year. Tracked birds averaged about 44,000 miles (70,900 km).

  • Octopuses have three hearts and blue, copper-based blood.

  • Honeybees share where flowers are with a waggle dance that encodes both direction and distance. Karl von Frisch won a Nobel Prize in 1973 for decoding it.

  • Tardigrades -- tiny water bears about half a millimeter long -- survived direct exposure to open space on a 2007 satellite mission.

You

Original artwork: a glowing web of nodes joined by soft pink threads, like neurons firing in a brain, scattered across a deep violet darkness.

The most amazing thing you will see today might be in the mirror.

  • Your brain has roughly 86 billion neurons.

  • Your body is built from roughly 30 to 37 trillion human cells, all working together right now.

  • Nearly every element in your body heavier than hydrogen and helium was forged inside stars. You are made of very old stardust.

  • Moonlight reaches your eyes about 1.3 seconds after it leaves the Moon. Some starlight you see tonight left its star before you were born.

  • Goosebumps, chills, and tears are some of the most common things people feel in their bodies during awe.

Us

Original artwork: the curve of Earth at night seen from orbit, with golden city lights scattered across the dark land, a thin blue glow of atmosphere along the edge, and the first light of sunrise at the right.

Some of the most awe-inspiring things on Earth are things people did together.

  • Smallpox killed hundreds of millions of people. In 1980, the world declared it eradicated -- the first human disease ever wiped out.
