The days of oil may be numbered, but there's another natural resource that's never been touched, Asteroids.

Asteroid mining sounds like something out of a bad space movie, but harvesting materials from space rocks might be our ticket to building space colonies or living on Mars.

Water covers over 70% of the Earth, cycling from the oceans and rivers to the clouds and back again. It even makes up about 60% of our bodies. But in the rest of the solar system, liquid water is almost impossible to find. So how did our...

Because of space physics, one faraway asteroid is likely the progenitor of almost a third of all the meteorites on Earth.

Are there ways to terraform Mars -- that is, make it habitable for humans? Some scientists think so. They have big plans, but they also face some big obstacles.

The spiral of the Milky Way is not as smooth as we once thought because an arm not so far from home appears to be broken! And we may have discovered the answer to why a local asteroid puts on the appearance of a comet.

Buckle up for a trip to the asteroid belt -- though it's not nearly as dangerous out there as you might think. But there's a LOT waiting to be discovered, including some crucial clues about the formation of the solar system itself.

In today's Crash Course Astronomy, Phil takes a look at the explosive history of our cosmic backyard. We explore how we went from a giant ball of gas to the system of planets and other celestial objects we have today.

The moon's South Pole-Aitken basin is the largest known crater in existence, and there's something big hidden underneath.

In the past few years the rise of crowdfunding has allowed for some pretty cool stuff to start existing, and today Hank is excited to announce another awesome Kickstarter - Planetary Resources (of asteroid mining fame) in partnership...

Could we have a possible 9th Planet? Hank Green tells us what we think we know with this elusive object.

Jessi introduces you to some of the most newly-named members of the solar system: the five dwarf planets!

The largest planet in our solar system is no stranger to throwing its weight around, both to our benefit and detriment here on Earth.

In this video Paul Andersen explains the parts of the Solar System; including the planets, dwarf planets, moons and asteroids. He explains how everything orbits around the Sun and how a proper understanding of this heliocentric model...

Our journey through the solar system continues, as Jessi gives you a close look at comets and asteroids!

New research is changing our ideas about the history of Mars's moons and we might have found the most active region of space.

Today on Crash Course Astronomy, Phil explains comets. Comets are chunks of ice and rock that orbit the Sun. When they get near the Sun the ice turns into gas, forming the long tail, and also releases dust that forms a different tail....

This video is answering the question of what happens if an asteroid gets close to a planet.

This video is answering the question of how big are asteroids.

This video is answering the question of how are asteroids like planets.

They are younger than the dinosaurs and could be gone in a cosmic blink. Why are Saturn's magnificent rings disappearing so fast? And what dramatic event created them so recently? Dive into the mysteries uncovered by the Cassini mission...

The first flight mission for planetary defense, NASA's Double Asteroid Redirection Test (DART) seeks to validate a method to protect Earth from the threat of an asteroid impact. By smashing a spacecraft into the smaller member of the...

Water on earth is found in all three forms. But how did water get on earth? Where did the water on earth come from? The earth has an estimated 325 million trillion gallons of it. But earth began as a barren,...
