About space

Thousands of years ago, on a small rocky planet orbiting a modest star in an ordinary spiral galaxy, our remote ancestors looked up and wondered about their place between Earth and sky. Today, we ask the same profound questions:

• How did the universe begin and evolve?
• How did we get here?
• Where are we going?
• Are we alone?

Today, after only the blink of an eye in cosmic time, we are beginning to answer these questions. Space probes and space observatories have played a central role in this process of discovery.
Our missions and research generate most of the coolest news coming out of NASA. We are responsible for all of NASA's programs relating to astronomy, the solar system, and the sun and its interaction with Earth. Our science stretches from the middle levels of Earth's atmosphere to the beginning of the universe, billions of light years away.
Our web site serves our science community, educators, government decision-makers, and the public. We hope your visit is enjoyable. Thanks for stopping by!
