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.
NASA's Dawn spacecraft has the protoplanet Ceres in its sight, and soon will have a close encounter with this unusual alien world. Still, before Dawn get's there, it may help to answer some questions such as "what exactly is Ceres?"
NASA has recently released a new and educational short films on the asteroid Bennu, a near-Earth space rock that the agency hopes to be collecting samples from by 2018. This mission is a precursor to a larger mission, where NASA will attempt to physically capture an asteroid and bring it into the moon's orbit for further study.
In a case of mistaken identity, a newly active asteroid in our solar system's famous Main Belt is boasting a dusty tail, thinking it's more a comet than an asteroid, according to recent research.
Astronomers have noticed that Earth has had a travel buddy for the last few centuries, and that friend will be sticking around for some time as a "quasi-satellite of Earth."
Government auditors were recently looking into why exactly the United States is falling behind in disarming itself of its old nuclear weapon surplus, and they stumbled upon an unusual excuse: asteroid defense.
