NASA and ESA to test nudging asteroids off collision course with Earth

At least nine asteroid missions are underway or coming soon, a recognition of these objects' scientific fascination — and their potential danger.

Jupiter has often been thought to protect the inner Solar System from asteroids and comets, but new research has shown that the giant planet may actually increase the risk of an impact.

The apparent non‑gravitational acceleration the extra-solar-system ‘Oumuamua exhibits is puzzling. We find that when the position and velocity of the Sun is correctly set in computing the predicted orbit, ‘Oumuamua’s trajectory can be explained with gravity and we have reproduced the unexpected gap by computation. We also propose to search for new extra-solar-system high speed...

Forget Armageddon-sized rocks, just one of 25,000 smaller asteroids could destroy a city on Earth. How to Kill an Asteroid by Robin George Andrew shows how science plans to save the planet

Asteroids that regularly fly between Earth, Venus and Mars could provide radiation shielding for human missions to explore neighbouring planets

Cracks running through samples of asteroid Ryugu were probably formed by the repeated thawing and freezing of water inside it, which could have helped asteroids like this carry the building blocks of life to early Earth

Bacteria grown from carbon compounds in asteroids could be turned into a kind of nutritionally balanced milkshake

Asteroids that regularly fly between Earth, Venus and Mars could provide radiation shielding for human missions to explore neighbouring planets

Scientists in New Mexico conducted several experiments and learned that asteroids can be deflected from Earth using explosions of nuclear warheads above the space rock's surface.

Samples from the asteroid Ryugu contain key ingredients in the biological cookbook.

NASA is on alert. The U.S. space agency is closely tracking two asteroids that would be making a close encounter with our planet. There is no need to be alarmed as the first asteroid is 130 feet in diameter and at

It's the end of the world in "Don't Look Up," and it's all thanks to a comet heading straight towards Earth. Dr. Amy Mainzer, a science consultant on "Don't Look Up," breaks down a few scenes from the film and explores the science behind near-Earth objects.

This innovative facility will be at the front line of Earth defense by searching for "killer" asteroids and comets. It will map large portions of the sky nightly, making it an efficient sleuth for not just asteroids but also supernovae and other variable objects.

A new study provides a possible explanation for the mysterious flares. The suggestion is that there is a cloud around Sgr A* containing hundreds of trillions of asteroids and comets, which have been stripped from their parent stars.

A private space telescope mission that aims to discover 500,000 near-Earth asteroids is technically sound and on track for a 2017 launch, a review panel says.

A new international effort will monitor potential asteroid threats and examine how to deflect them before they hit Earth.

If a dangerous asteroid pops onto the radar with no time to spare, nuclear bombs may be the best way to respond.

The space agency's $650 million Neo Surveillance Mission is designed to spot killer asteroids.

The three asteroids flying by the Earth tonight range in size from the smallest at 55 feet to the largest at a whopping 255 feet in diameter. They will all be too far away to impact with the planet.

Each of the asteroids flagged by a computer algorithm at Leiden University are more than 328 feet wide and will pass close between the Earth and the moon between the years 2131 and 2923.

As a physicist at NASA’s Jet Propulsion Laboratory, Marina Brozovic studies and measures near-earth asteroids—you know, the ones that can potentially cause catastrophic damage. Watch as Brozovic explains how her team tracks the orbit of these large masses and how NASA would prepare if one were to come barreling towards earth.
