Collaborate Disseminate
NASA has been watching the skies for potentially hazardous asteroids for decades, but there are some factors that the existing Sentry program couldn’t account for. The second-generation system, Sentry-II, has now gone online, allowing astronomers to ca… Continue reading NASA’s asteroid-impact monitoring system gets accuracy upgrade
Accounting for where all of the Earth’s water came from is a longstanding puzzle, but an international team of scientists led by the University of Glasgow has proposed that the Sun may be a major source of our planet’s H₂O, by way of hydrogen from the … Continue reading Asteroid analysis suggests some of Earth’s water came from the Sun
NASA has launched its Double Asteroid Redirection Test (DART) mission to demonstrate a possible way to deflect asteroids that could pose a threat to the Earth sometime in the future. Today at 1:21 am EST (06:21 GMT), the robotic probe lifted off atop a… Continue reading DART spacecraft is now on its way to crash into an asteroid
A curious space rock has just gotten curiouser. The asteroid Kamo`oalewa has an odd orbit that makes it almost a mini-moon of Earth – and now it may really earn that title, as new observations show that it could in fact be a fragment of the Moon.Contin… Continue reading Odd asteroid seems to be a broken piece of the Moon
A first-of-a-kind NASA launch took place over the weekend, setting the agency’s Lucy spacecraft on a pioneering path to study an unprecedented number of asteroids as part of a single mission. Among them are the Trojan asteroids that both trail and lead… Continue reading NASA’s pioneering Lucy probe takes off to study Trojan asteroids
The world faces many terrestrial crises right now, so it’s easy to forget that giant space rocks may one day threaten the very existence of entire civilizations. Yes, the threat …read more Continue reading NASA Are Squaring Up Against the Asteroid Threat

About 66 million years ago, a gigantic object crashed into the Earth, triggering a mass extinction that took out the dinosaurs. Now, scientists from Southwest Research Institute say they’ve traced the culprit back to its point of origin, identifying it… Continue reading Dinosaur-killing rock traced to population of “dark primitive asteroids”
Around 66 million years ago, a gigantic asteroid smashed into the Earth and brought the 160-million-year reign of the dinosaurs to an end. Now, researchers have discovered direct evidence of this world-changing cataclysm in the form of fossilized “mega… Continue reading Fossilized “megaripples” record huge tsunami from ancient asteroid impact
