ASTEROID

What will kill off humanity and destroy the globe? It will probably be an event of our own creation, rather than a natural disaster.

NASA has released a simulation of a planetary body that collided with Earth during the early days of it's formation which delivered precious metals such as gold and platinum.

An asteroid considered "potentially hazardous" by NASA is set to skim the Earth’s atmosphere just days before Christmas.

The first observed interstellar asteroid in our solar system is different, far longer than other asteroids.

To put astronauts on the moon and mine asteroids for their resources, China plans to develop rockets that run on nuclear power instead of chemical fuel.

Scientists have found a meteorite that broke off a massive asteroid we have yet to discover.

An asteroid called Chicxulub Impactor hit Earth about 66 million years ago, creating conditions for a mass extinction event that killed all non-avian dinosaurs.

Scientists are using a metal in the asteroid that killed the dinosaurs to destroy cancer cells and treat the disease.

These pictures from deep space show how a bunch of asteroids got in the way of a Hubble Space Telescope.

The devastating asteroid impact that killed off the dinosaurs during a mass extinction event would have released enough gas into the atmosphere to seriously cool off Earth.

NASA is working on two efforts to develop compact technologies that could help understand comets better and maybe even deflect asteroids on a collision course with Earth.

A comet — it could also be an asteroid — made its closest approach to the sun Sept. 9, and it could be the first known object from outside the solar system to enter it.

NASA has extended the Dawn mission to 2018 to study Ceres up-close. The space probe hopes to capture the celestial event, which will help us understand the atmosphere around the dwarf planet.

This asteroid is just one big pile of rocks traveling through space together.

Scientists have determined the origin of organic material found earlier this year in Ceres using NASA's Dawn space probe.

A weird asteroid orbits the Earth and the sun at the same time.

Planetary defense specialists tracked an asteroid headed for Earth. Here's how their global asteroid-impact early-warning system performed.

Asteroid scientists are testing whether or not the system would actually save Earth if a space rock threatened us with a devastating crash.

An asteroid NASA has only seen once before is set to flyby Earth next week.

Lockheed Martin has laid out a plan that involves NASA and the spacecraft Orion coming together to design a Mars Base Camp that can be reused and possibly run on frozen asteroid ice.

Scientists bounced a spacecraft off the bottom of Earth so it could reach an asteroid, take samples and bring them back home.
