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?
After only the blink of an eye in cosmic time, we are beginning to answer these questions. Looking for images and resources to help explore some of these questions? These links provide a good place to explore space science starting with a closer look at the Sun, planets, stars, and galaxies. |
