The six-mile-wide asteroid punched a one-way ticket toward extinction for all non-avian dinosaurs. Some 66 million years ...

Buried "megaripples" — some the size of five-story buildings — are helping scientists piece together the devastation ...

Lucy is preparing for a close encounter with the asteroid Donaldjohanson, a key milestone before its groundbreaking journey ...

It measures 130 to 300 feet across, a pebble compared to the asteroid that killed the dinosaurs, which is estimated to have been six to nine miles in length. On the other hand, on Feb. 15, 2013, an ...

The main belt asteroid Donaldjohanson is now in sight as the Discovery Program mission prepares for a flyby of the object in ...

so a larger telescope like Webb can help narrow down the asteroid's true trajectory. The Webb telescope, launched in 2021 as an international partnership of NASA, the ESA and the Canadian Space ...

In 2021, NASA gave the all-clear to another potentially worrisome asteroid, Apophis, after new telescope observations ruled out any chance of it hitting Earth in 2068.Should we worry about ...

In the case of Apophis, further observations eventually allowed astronomers in 2021 to rule out the possibility of an impact when the asteroid makes a close flyby to Earth in 2029 and again in 2036.

That asteroid, called the Chicxulub impactor ... Enter Deniz Burnham, who joined the NASA 2021 Astronaut Candidate Class. She has a bachelor’s degree in chemical engineering from the University ...

But scientists revised that assessment after a precise analysis of the asteroid’s orbit in 2021. And scientists are expecting similar forecasting trends with 2024 YR4, which currently sits at a ...

The $10 billion orbiting observatory will give astronomers a better sense of the near-Earth asteroid 2024 YR4's size and position.
