In a case of mistaken identity, a newly active asteroid in our solar system's famous Main Belt is boasting a dusty tail, thinking it's more a comet than an asteroid, according to recent research.
Astronomers have noticed that Earth has had a travel buddy for the last few centuries, and that friend will be sticking around for some time as a "quasi-satellite of Earth."
Government auditors were recently looking into why exactly the United States is falling behind in disarming itself of its old nuclear weapon surplus, and they stumbled upon an unusual excuse: asteroid defense.
If a dangerous meteorite comes heading Earth's way, there's actually only a 10 percent chance that experts behind NASA's near-Earth object (NEO) tracking program will even notice it in time to warn an endangered public.
A newly discovered asteroid will zoom within 25,000 miles of Earth this Sunday, giving astronomers the unique opportunity to observe this fast-moving celestial object.
NASA's Spitzer Space Telescope has spotted what it suspects is an asteroid smashup - the type of collision that can lead to the formation of new planets, according to a new study.
... well, sort of. Experts have determined that a massive asteroid that is due to orbit dangerously close to the Earth is actually composed of rubble spinning at an incredibly fast rate. Somehow, these surface rocks aren't tearing away from the whole to fly off into space, and astrophysicists are wondering why.
Researchers have recently developed the "most accurate model to date" of solar wind affecting an asteroid - a phenomenon that, you may be surprised to learn, could be very dangerous to unprepared astronauts during asteroid missions planned for the near future.
NASA plans to send out a robotic spacecraft to hunt down and capture an asteroid. Once caught, the asteroid will be brought into a stable orbit around the Moon, where it can freely float until astronauts head out to study it in person at a later date.
NASA researchers captured stunning images of the huge near-miss asteroid, dubbed "The Beast," that skimmed past Earth on Sunday.
A potentially dangerous asteroid nicknamed "The Beast" - first discovered April 23- is flying by Earth on Thursday and its trek will be broadcast live via the Slooh Space Camera starting at 11:30 a.m. PDT/2:30 p.m. EDT.
A fake CNN iReport that saw more than 300,000 hits before being taken down by the news agency claimed that a "Manhattan-sized" asteroid was headed for Earth and would make impact by 2041.
NASA astronauts Stan Love and Steve Bowen went underwater May 9 to test tools that will be used for a planned asteroid capture mission in the 2020s.
A small, bus-sized asteroid passed within 186,000 miles (300,000 kilometers) of Earth - closer than the Moon - on Saturday morning, but posed no threat to our planet, Space.com reported.
A new study shows an asteroid impact many times more powerful than the one that killed the dinosaurs probably hit the Earth about 3.2 billion years ago - a cataclysmic event that changed the world's tectonic activity, created a vast array of geological features, and contributed to a shift in evolutionary patterns.
