ASTEROID

Astronomers at the Arecibo radio telescope in Puerto Rico took radar images of the large asteroid Phaethon as it passed close to Earth this month.

The asteroid ‘Oumuamua that scientists discovered to be an interstellar traveler to our solar system is special in how similar it is to objects that were born here.

The 3200 Phaethon will pass by Earth Saturday.

A group is looking for alien signals from the bizarre-looking asteroid that is the first to visit our solar system from another place.

NASA's New Horizon space probe will encounter the mysterious MU69 in the Kuiper belt on New Year's Day 2019. New data analysis shows that the object could be a binary system with an orbiting moon.

2017 was a great year for NASA, these are just some of the research, findings, and event highlights from the year.

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

A new trajectory means the mission to uncover core facts about the asteroid belt will happen sooner than planned.

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.

Having discovered an asteroid from outside the solar system for the first time, scientists are hoping there are more out there – illuminating the path to extrasolar worlds.

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.
