Shooting stars are not stars at all. They are tiny space adventurers who accidentally wander into our sky and get sucked toward us by Earth's gravity. Here's the story of a shooting star's journey.
Throughout the world, unique sites of natural and cultural heritage are protected for future generations. But what about sites on the moon that represent the beginning of the human space age?
Satellites hundreds of miles overheard are helping scientists to predict drought, track floods and see how climate change is changing access to water resources.
Can China build a lunar base? Absolutely. Can human beings survive on the Moon and other planets for the long term? The answer to that is less clear.
Life could exist in another solar system in a different part our galaxy. Or in another galaxy far away. We don't have the perfect technology yet to study such far away places but we're still trying.

There are lots of places where it's much, much hotter than the Sun. And the amazing thing is that this heat also makes new atoms - tiny particles that have made their way long ago from stars to us.
