The source of water on Earth, the Moon and planets in our solar system is hotly debated. Some in the planetary science community argued that it came from asteroids and comets. Now they have proof.

Though it’s fairly straightforward to locate the Earth’s moon in space today, there is a fundamental gap in our understanding of how it got there.
The far side of the Moon sees its share of sunlight – it’s dark only in the sense that it’s mysterious because it’s never visible from Earth. Here’s why.
Compared to other governments’ support of lunar business and technology, Canada needs to be more strategic and active in lunar exploration or we will be left behind.
Israel’s first moon mission failed to land successfully on the moon’s surface.
Meteorites might look like boring bits of rock – but each one has a fascinating story.
As commercial spaceflight companies lower the cost of reaching space, nations can launch more missions. But while astronauts are great for whipping up enthusiasm, is a manned mission worth the cost?
There are three ways heat can be shared: conduction, convection and radiation. Find out which one lets heat travel through space.
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.
Here’s what NASA scientists discovered when an astronaut went into space and his twin remained on Earth.
When you look up at the vastness of space you can see hundreds, thousands and even millions of years into the past.
At the end of the day, the problem is that no-one on Earth wants nuclear waste stored near them, and it’s not safe or cost-effective to blast it into space.
Whatever your age, whatever your favourite topic – space, animals, nature, physics, how bodies work – we’ve got a Curious Kids article for you.
Fifty years ago people saw our planet from the outside for the first time.
Apollo 8 was the moment that humanity realised a dream conceived in our cultural imagination over two millennia ago.
A bright comet visible in December provides an excellent viewing opportunity for night sky lovers – even potentially with the naked eye.
