A new study suggests that millions of tiny space rock fragments, which were ejected from the 2022 collision between asteroid Dimorphos and NASA's DART spacecraft, may be on a collision course with Earth and Mars.

The boulders range in size from three feet to 22 feet.

Using the NASA/ESA Hubble Space Telescope, astronomers have spotted 37 boulders that were possibly shaken off Dimorphos.

When a NASA spacecraft successfully knocked an asteroid off course last year it sent dozens of boulders skittering into space, images from the Hubble telescope showed on Thursday.

The Double Asteroid Redirection Test (DART) has left a vast field of rubble strewn around asteroid Dimorphos, Hubble images show.

The Kuiper Belt is a massive disk of icy bodies, including Pluto, that is located just outside of Neptune's orbit in our solar system. Objects observed in the Kuiper Belt exhibit a more diversified color range than any other solar system population, with colors ranging from white to dark reddish. While the source of this diversity in colors is unknown, scientists have speculated that it is likely the result of the…

A strange comet-like object discovered over 5 years ago was the first known visitor from another solar system. Its movement though space was so odd that scientists struggled to explain it, until now.

NASA's Hubble Space Telescope just came across the largest icy comet to date.

Don't worry. It won't get anywhere near Earth…probably.

Starlink satellites burn up in Earth's atmosphere after five years. Some researchers worry this injection of metals in the upper atmosphere could be damaging.

Boom.

NASA says the Hubble Space Telescope has found nearly 40 boulders that were potentially shaken off the asteroid Dimorphos following its DART test last year.

NASA said that redirecting an asteroid could lead to "a cluster of threatening boulders heading in our direction."

Wayward asteroids present a real collision hazard to Earth. Scientists estimate that an asteroid measuring several miles across smashed into Earth 65 million years ago and wiped out the dinosaurs, among other forms of life, in a mass extinction. Unlike the dinosaurs, humanity can avoid this fate if we begin practicing how to knock an Earth-approaching asteroid off course.

One astronomy professor called the notions "highly questionable" and "odd."
