Scientists discovered that a single massive asteroid impact could have delivered and spread Mercury's polar water ice in just 176 Earth days. New simulations show how the closest planet to the sun ended up with vast frozen water deposits despite scorching 800-degree temperatures.
Scientists in Western Australia just confirmed the oldest known asteroid impact on Earth, dating back three billion years. The discovery could unlock secrets about how life began on our planet.
Researchers discovered fossilized fish in North Dakota with tiny glass beads from the dinosaur-killing asteroid lodged in their gills, proving they were alive when the impact debris rained down. It's the most direct evidence yet of what happened in the first hour after Earth's most famous catastrophe.
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.
For the first time ever, humans have measurably shifted the orbit of a celestial body around the Sun. When NASA deliberately crashed a spacecraft into an asteroid in 2022, the impact changed the path of not just one asteroid, but two.
A Silicon Valley nonprofit is working to protect our planet from dangerous asteroid impacts through research, education, and global cooperation. Since 2002, the B612 Foundation has been advancing asteroid detection and deflection strategies while teaching the world about these cosmic threats.
Four years after NASA crashed a spacecraft into an asteroid to test Earth's defenses, scientists confirmed it worked even better than expected. The impact not only changed the asteroid's path but altered its orbit around the Sun for the first time in human history.
The asteroid once called the most dangerous discovery in 20 years is no longer a threat to Earth or the moon. Thanks to the James Webb Space Telescope, scientists have completely ruled out any chance of impact.
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.
A 60-meter asteroid has a 4% chance of striking the moon on December 22, 2032, and scientists are getting ready to study the impact of a lifetime. The collision could unlock secrets about the moon's interior, geology, and history without any artificial intervention.
Scientists discovered that a single ancient asteroid collision may have reshaped nearly the entire surface of Deimos, Mars' mysterious smaller moon. New computer simulations and spacecraft images reveal how one impact created both the moon's giant southern crater and its strangely smooth, dusty surface.
That asteroid scientists were watching? New data from the James Webb Space Telescope just confirmed it will safely miss the Moon in 2032. What looked like a small chance of impact turned into a clear all-clear thanks to unprecedented observations.
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 Chinese spacecraft just arrived at one of Earth's smallest companion asteroids after 13 months of travel. Scientists believe the tiny space rock might actually be a piece of our moon, blown off by an ancient impact.
Rare lunar samples from China's Chang'e-6 mission just solved a 4-billion-year mystery about how a massive asteroid collision changed the Moon from the inside out. The discovery explains why one side of the Moon looks so different from the other.
The most dangerous asteroid ever discovered won't hit Earth or the moon after all, thanks to NASA's powerful James Webb Space Telescope tracking it 280 million miles away. Scientists now have proof that asteroid 2024 YR4 will safely pass by both worlds in December 2032.
Amateur astronomers with smart telescopes are joining NASA missions to track dangerous asteroids and discover comets. One citizen scientist in South Africa captured crucial data during NASA's asteroid deflection test.
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.
China is preparing to slam a spacecraft into an asteroid at a jaw-dropping 9 kilometers per second, nearly 50% faster than NASA's groundbreaking mission. The ambitious planetary defense test could actually change an asteroid's path around Earth before 2030.
