NASA's DART planetary defense test hit an asteroid. Watch what happened next. | Mashable

The 1998 blockbuster Armageddon was about a fictional last-ditch attempt by NASA to stop a speeding asteroid headed toward Earth.

Now, 25 years later, the U.S. space agency has a movie showing just what asteroid-kicking really looks like.

During the immediate aftermath of the DART mission — NASA's first asteroid target practice — the Hubble Space Telescope captured the hour-by-hour changes as the space rock cast off over 1,000 tons of debris.

NASA made history by knocking an asteroid off course. Now, it's publishing the data | WSIU

Last September, NASA made history by knocking an asteroid off course. A mission called DART crashed a spacecraft the size of a golf cart into an asteroid the size of the Great Pyramid in Egypt.

NELL GREENFIELDBOYCE, BYLINE: The asteroid is named Dimorphos.

GREENFIELDBOYCE: Once the spacecraft went whammo, those images stopped. But telescopes on the ground and in space showed that the impact kicked up a huge cloud of dust and debris.

Astronomers still have their eyes on that asteroid NASA whacked

Astronomers are still watching that asteroid that NASA whacked with a spacecraft back in September, in the first-ever test of whether an asteroid could be deliberately pushed off-course.

Almost immediately after NASA's Double Asteroid Redirection Test (DART) mission sent a golf cart-sized spacecraft crashing into an asteroid called Dimorphos, scientists hailed it as a huge success – and a powerful demonstration that an asteroid's trajectory can be altered.

The asteroid once thought to be one of Earth's biggest risks

EARTH ( WETM ) – It’ll show up a few more times before 2029, but when it does, the people of Earth won’t have anything to worry about.

The story of Apophis starts in 2004. The 1,100-foot rock was picked up by scientists in the summer, and it was nothing remarkable, according to Scientific American. But in a matter of months, calculations of its orbit determined it had a 1-in-37 (2.7%) chance of hitting Earth in April 2029.

NASA snapped close-up pics of passing asteroid 2011 AG5 | SYFY WIRE

In the 2014 disaster movie Asteroid vs. Earth (now streaming on Peacock !), astronomers discover a wave of impactors on a collision course with our planet.

On Feb. 3, 2023, the asteroid known as 2011 AG5 made its closest approach with Earth, toppling slowly end over end as it cruised by.
