Three Billion Years Ago, a Giant Impact Boiled Away Some of Earth's Ocean. Then Life Bounced Back

The ancient S2 asteroid impact, though catastrophic, led to a boost in Earth's early biosphere by enriching oceans with essential nutrients.

Scientists Find Evidence Earth Used to Have a Ring Like Saturn

Earth possibly had a temporary ring system formed from an asteroid, affecting meteor impacts and climate during the Hirnantian Icehouse.

Asteroid that eradicated dinosaurs not a one-off, say scientists

The asteroid impacts at the end of the Cretaceous period may have occurred in clusters, not just one isolated event.

The German town that's encrusted in 72,000 tonnes of DIAMONDS

Diamonds in buildings of Nördlingen created by asteroid impact; town sits within a crater.

Asteroid that wiped out the dinosaurs 'came from beyond Jupiter'

The origin of the asteroid that ended the dinosaurs has been traced to beyond Jupiter, revealing its significant impact on life 66 million years ago.

The Dinosaurs Had Even Worse Luck Than Scientists Imagined

The Chicxulub impact led to massive extinctions on Earth, triggering the rise of mammalian ancestors, fundamentally reshaping life on our planet.

The asteroid that killed the dinosaurs was NOT alone, scientists say

A second asteroid impacted Earth in the same year that dinosaurs were wiped out, offering new insights into this extinction event.

An asteroid wiped out the dinosaurs, not a comet, new study finds

Recent research reaffirms the Alvarez hypothesis, attributing dinosaur extinction to a massive asteroid impact rather than a comet.

A 'Chicken From Hell' Could Rewrite the Story of the Dinosaurs' Final Days

The theory that dinosaurs were already declining before the asteroid that wiped them out is being challenged by a newly identified species.
The decrease in dinosaur diversity in the last few million years of the Cretaceous may be due to biases in fossil preservation rather than a true decline in population.

The asteroid hunters: how new technology will help save Earth from a catastrophic collision

A small asteroid recently went unnoticed before impacting Earth harmlessly, underscoring the ongoing need for planetary defense against larger threats.

NASA simulates asteroid heading toward Earth - does humanity pass its test?

A hypothetical scenario tested by NASA involved planning for a potential asteroid impact with a 72% chance of hitting Earth in 14 years.

NASA's DART mission punched the Didymos asteroid in 2022 - now it's time to go back

ESA's Hera mission prepares to investigate impact on asteroid to develop asteroid deflection systems.

NASA's DART Mission Snapped Pictures Until It Crashed Into An Asteroid. Here's What Those Images Reveal

NASA's DART mission successfully altered asteroid motion, providing valuable insights into binary asteroid system characteristics.

Asteroid set to hit Earth's atmosphere in matter of HOURS

A small asteroid will enter Earth's atmosphere today, burning up before impact, but visible as a fireball over the Philippines.

NASA simulated an incoming asteroid impact, and the biggest roadblock to action was penny pinchers in Congress

Politics, not technology, presents the biggest challenge in addressing the threat of a large asteroid impacting Earth.

SpaceX satellites threaten to hide asteroids that pose danger to humanity

Early detection of asteroid impact near Berlin led to successful tracking and no harm, underscoring significance of planetary defense systems.

Jupiter's moon Ganymede was struck by asteroid bigger than dinosaur-killing rock

Ganymede's rotation was altered due to an ancient asteroid impact, leading to significant geological and potentially oceanographic changes on the moon.

Scientists Finally Know Where the Dinosaur-Killing Asteroid Came From

The asteroid that caused the dinosaurs' extinction likely originated beyond Jupiter, carrying ancient stellar traces.

An Asteroid Wiped Out Dinosaurs. Did It Help Birds Flourish?

Birds began diversifying tens of millions of years before the asteroid impact that caused the mass extinction.
The asteroid impact did not have a major effect on bird evolution, as previously believed.

Asteroid that struck Berlin last week could be very rare space rock

Fragments of an asteroid that struck the Earth over Berlin last week have been discovered and are considered rare.
The rock fragments resemble rocks found on Earth, making them unusual for meteorites.
