New evidence suggests that periodic mass extinctions occurring over the past 260 million years are directly linked to comet or asteroid showers.
Dinosaur extinction was caused by an asteroid impact 66 million years ago that also triggered a series of volcanic eruptions, say researchers from the University of California Berkeley.
Congratulations! You survived another potential doomsday! Very early this morning, a 'massive' asteroid hastily whizzed past Earth, off to some other part of the solar system where it will wreak untold havoc - or, more likely, just keep flying solo. So why is it that some groups are saying NASA had it wrong about this 'near-miss' Armageddon?
University of Gothenburg researchers recently found a double crater in Sweden that suggests a unique twin meteorite event occurred 458 million years ago. This is the first proven occurrence of such an event.
Sixty-six million years ago, a massive asteroid struck Mexico's Yucatán Peninsula. As a result, the Earth changed forever, spelling the end of the dinosaurs and ushering in a new age where other animals could flourish. Now new research has revealed that it wasn't mammals who inherited the Earth, but fish.
Glass deposits discovered in impact craters on the surface of Mars may hold signs of ancient life, adding to the growing evidence that the Red Planet was once habitable.
The great Chicxulub impact is known for supposedly killing all of the dinosaurs on Earth, but new research suggests that this famous asteroid also wiped out unseen mollusks, making scientists question the role played by ocean acidification.
About 65 million years ago, an asteroid crash supposedly wiped out all the dinosaurs on Earth. Now, scientists may soon finally solve the mystery behind this dino-killing crash.
Enthusiasts who have been following NASA's mission plans closely might be a little disappointed with the space agency's latest decision concerning the historic Asteroid Redirect Mission (ARM). The mission, the very name of which held the promise of physically capturing an asteroid, will now simply be plucking a boulder from the surface of a hurtling space rock as it flies by in 2022.
NASA's Dawn probe arrived at the massive asteroid known as Ceres last Friday morning (Mar 6), making history as the first manmade spacecraft to achieve orbit around what astronomers call a "planetoid," or dwarf planet.
You probably heard about it. Last Monday morning, amateur stargazers and professional astronomers alike looked to the heavens to watch the asteroid known as 2004 BL86 glide by Earth. And while NASA's near-Earth object (NEO) tracking program had long known that this brief visitor was no threat to our planet, it still was a fascinating subject of study.
An asteroid, designated 2004 BL86, will safely swing by Earth next week, marking the closest near-Earth flyby of any known space rock ever.
NASA's unique Dawn spacecraft has already traveled more than three billion miles since its 2007 launch, and has made some serious changes in course after visiting a mysterious protoplanet, known as Vesta. And yet, it's still far from being out of fuel. How can this be? In a new video from NASA, experts at the Jet Propulsion Laboratory explain the wonders of ion propulsion.
It is thought that about 66 million years ago, a massive impact led to the full extinction of the dinosaurs (potentially with the help of volcanoes and disease), and a significant portion of prehistoric sea life. Now researchers have found evidence that even the great majority of mammals at this time did not escape destruction.
You may have seen some headlines this week like "Mountain-Sized Asteroid is Heading for Earth!" or "Dangerous Asteroid Headed our Way," but you shouldn't trust the hype. According to NASA's Near-Earth Object Program (NEOP) office, that huge asteroid heading our way isn't even close to being a threat.
