The universe is stranger and more beautiful than you can imagine
The Sun contains 99.86% of all mass in the Solar System. Over one million Earths could fit inside it.
Light travels 299,792 km every single second — yet it takes 4.2 years to reach the nearest star.
So dense that not even light can escape. Sagittarius A* at the center of our galaxy is 4 million solar masses.
The observable universe spans 93 billion light-years and contains an estimated 2 trillion galaxies.
27% of the universe is dark matter — invisible, undetected, yet it shapes everything we see.
Webb can see light from 13.6 billion years ago — just 200 million years after the Big Bang.
The Milky Way is a barred spiral galaxy approximately 100,000 light-years in diameter. Our Solar System sits quietly in the Orion Arm, 26,000 light-years from the galactic core — a supermassive black hole known as Sagittarius A*.
The milestones that shaped humanity's journey into the cosmos
The Soviet Union launched the first artificial satellite into Earth's orbit, igniting the Space Age.
The first human in space completed one orbit around Earth aboard Vostok 1 in 108 minutes.
Neil Armstrong and Buzz Aldrin became the first humans to walk on the Moon. "One giant leap."
Launched into orbit, Hubble has revolutionized our understanding of the universe with breathtaking imagery.
Spirit and Opportunity landed on Mars. Opportunity continued operating for an extraordinary 15 years.
The most powerful space observatory ever built. It observes galaxies from just after the Big Bang.
NASA's crewed lunar program. Aims to establish a permanent presence on the Moon and pave the way to Mars.
