In 1908, a cosmic airburst flattened 800 square miles of Siberian forest with hundreds times the energy of Hiroshima, yet left no crater. Scientists now understand why, and it's helping protect Earth today.
Space agencies have discovered 95% of large asteroids that could threaten Earth, and none are heading our way. New telescopes launching soon will help scientists find and track the smaller ones even faster.
Two space agencies are joining forces to study asteroid Apophis when it zooms past Earth in 2029, offering scientists a once-in-a-lifetime chance to learn how gravity reshapes space rocks. The mission shows international cooperation reaching new heights in planetary defense.
Two major space agencies just signed a historic agreement to send a spacecraft to asteroid Apophis during its rare close flyby of Earth. The mission will gather crucial data to help protect our planet from future asteroid threats.
Japan and Europe just signed a historic agreement to study an asteroid that will fly closer to Earth than satellites in 2029. The mission will help protect our planet from future space rocks.
A Southern California company is launching the first commercial deep space mission to study asteroid Apophis during its 2029 Earth flyby, making planetary defense faster and more affordable. The mission could attract more viewers than the Super Bowl while helping protect our planet from future threats.
Thousands of automated cameras across the globe just helped scientists discover a brand new meteor shower created by an asteroid breaking apart near the Sun. This breakthrough reveals how space rocks behave and could help protect Earth from future threats.
The Rubin Observatory discovered more than 11,000 previously unknown asteroids during early test runs, offering a preview of how it will revolutionize our understanding of the solar system. What used to take years to find now happens in days.
A powerful new telescope has discovered 11,000 previously unknown asteroids in just its first test observations, revealing what scientists say will revolutionize our understanding of the solar system. The Vera C. Rubin Observatory accomplished in days what used to take years, offering a glimpse of discoveries to come.
A team at UC Santa Barbara has designed a system to blast dangerous asteroids into harmless bits using rockets and technology we already have. Unlike asteroid deflection methods, this "Pulverize It" program could work even with short warning times.
When a building-sized asteroid set Earth in its crosshairs last year, one British lawyer had to alert every government on the planet. Aarti Holla-Maini successfully activated the UN's planetary defense system for the first time ever.
A spacecraft just completed a supersonic speed boost in deep space, setting itself up to visit the asteroid that humanity deliberately smashed two years ago. The mission will help turn planetary defense from a one-time experiment into a repeatable safety system.
China is preparing to launch its first planetary defense mission in December 2027, aiming a spacecraft at asteroid 2016 WP8 to test humanity's ability to protect Earth from space threats. The mission marks another nation joining the effort to keep our planet safe from asteroids.
Blue Origin is partnering with NASA to protect Earth from dangerous asteroids using ion beams and high-speed impacts. The NEO Hunter mission will scan, deflect, and divert space rocks before they can threaten our planet.
NASA's asteroid defense mission captured the first proof that space rocks gently toss debris at each other like cosmic snowballs, reshaping surfaces over millions of years. The discovery came from images taken seconds before the spacecraft deliberately crashed into an asteroid in 2022.
A 100-meter asteroid once labeled the "most dangerous in decades" will safely pass the moon in 2032, scientists confirm using the James Webb Space Telescope. The advanced tracking eliminated fears of a lunar collision that could have disrupted satellites.
NASA's DART mission successfully knocked an asteroid off its path around the sun, proving we could defend Earth from a space rock threat. Amateur astronomers traveled the globe to confirm this planetary defense milestone.
Humanity just passed its first planetary defense test. NASA deliberately crashed a spacecraft into an asteroid in 2022, and new data confirms we successfully changed how two space rocks orbit the sun.
For the first time in human history, we've measurably changed how a space rock orbits the Sun. NASA's 2022 asteroid impact proved we can defend Earth from cosmic threats.
When NASA deliberately smashed a spacecraft into an asteroid in 2022, scientists hoped to prove we could defend Earth from space rocks. New data reveals the impact did something even better: it shifted the entire asteroid system's path around the Sun.
