Initially, much uncertainty surrounded the flight path of the space rock known as 2024 YR4, a small asteroid that has recently become an object of much scientific attention. 2024 YR4, measuring

NASA’s DART mission successfully altered an asteroid’s orbit, but scientists now say the impact also shifted the path of the entire asteroid system.

NASA’s Double Asteroid Redirection Test did more than shove a small moonlet off its local path. New peer-reviewed research confirms that the September 2022 collision measurably shifted the entire Didymos binary asteroid system’s orbit around the Sun,

Of all the asteroids that have imperiled the planet, 2024 YR4 is unparalleled. An Earth impact was eventually ruled out in February of last year. Now a concerted effort by astronomers indicates the

What happens if an asteroid the size of a 15-story building crashes into the Moon in 2032? While the chances of the newly discovered asteroid 2024 YR4 hitting the Moon in seven years are slim – there is currently a 96% chance it won't happen – an ...

A brilliant fireball meteor streaked across southeastern US skies on Thursday, June 26, 2025, creating a spectacular daylight display that was captured on multiple cameras and detected by sophisticated monitoring systems. The event generated more than 200 ...

NASA’s DART mission proved that a spacecraft can nudge an asteroid system in space, offering a real test of planetary defense. NASA’s DART (Double Asteroid Redirection Test) spacecraft changed the motion of an asteroid system in space,
