It’s the first mission of its kind, set to monitor our active and unpredictable Sun and help protect us from its violent outbursts – and…
Earlier this year, the discovery of a potentially hazardous asteroid took astronomers on a roller coaster ride. On January 6, 2022, astronomers at the Mount…
A space security expert explains NASA’s plans to prevent a potential catastrophe. The Earth exists in a dangerous environment. Cosmic bodies, like asteroids and comets,…
For a few tense days this January, a roughly 70-meter asteroid became the riskiest observed in over a decade. Despite the Moon’s attempt to scupper…
It’s a funny thing about homing in on an asteroid and calculating its path, future position, and probability of impacting Earth – it will often…

Update as of February 15: Additional analysis by, among others, citizen-scientist Bill Gray and colleagues at NASA’s JPL, now indicates that the object expected to impact the…
What if a 10 km (6.5 mile)-wide asteroid was on a bee-line towards Earth, with an impending, calamitous impact just six months away? This was…
Managed for NASA at the Jet Propulsion Laboratory, the Center for Near Earth Object Studies (CNEOS) accurately characterizes the orbits of all known near-Earth objects,…
UC Riverside astrophysicist explains the science. The James Webb Space Telescope, the most complex and expensive space laboratory ever created, is less than two weeks…
A new study has found that the mineralogy of the rocks that a meteorite hits, rather than the size of the impact, determines how deadly…
We sure are — all in the name of planetary defense. The DART mission is a technology test to see if an impactor could change…
When was the last time an asteroid hit Earth? Today! But it was almost definitely very small. Small asteroids and other tiny dust and particles…
The new system improves the capabilities of NASA JPL’s Center for Near Earth Object Studies to assess the impact risk of asteroids that can come…
NASA’s latest launch into outer space is going to make an impact. In fact, that’s its entire mission. DART (Double Asteroid Redirection Test), which launched…
Lighting up the California coastline early in the morning of November 24, a SpaceX Falcon 9 rocket carried NASA’s Double Asteroid Redirection Test (DART) spacecraft…
Is NASA aware of any Earth-threatening asteroids? Luckily there are no known asteroid threats to Earth for at least 100 years. But that doesn’t mean…
