Sometimes, it's hard to remember that Earth is constantly being bombarded by literally tons of space debris daily. The larger ...

At the start of each year, within a few days of all the New Year's Eve celebrations wrapping up, the sky itself puts on a ...

Every 2,000 years or so, a meteoroid the size of a football field hits Earth and causes significant damage to the area. Only once every few million years, an object large enough to threaten Earth ...

Cratered surfaces across our solar system reveal signs of ancient impacts, but mysterious gullies on Vesta might have formed through sudden brine flows triggered by meteoroid impacts. Recent ...

It came from the same direction as the most destructive meteoroid to impact Earth in a century, but it may be three times larger. And just like that asteroid that blew out windows in Chelyabinsk ...

In most cases, absolutely not, said Bill Cooke, head of NASA's Meteoroid Environment Office at Marshall Space Flight Center in Alabama. "If you are inside the ISS, meteoroids pose zero risk ...

This is the spectacular moment a meteor lit up the sky above Teruel and Cuenca in Spain. Footage shows the fireball streaking ...

A tiny rock fragment has hit the new James Webb Space Telescope's main mirror. The damage inflicted by the dust-sized micrometeoroid is producing a noticeable effect in the observatory's data but ...

To be considered a fireball, a meteor — a streak of light caused by a meteoroid that enters Earth's atmosphere — needs to reach magnitude -4, which means it appears brighter than Venus in the ...

Such events are generally associated with comets that orbit the sun, occurring when the Earth's orbit intersects with their paths and the meteoroid streams they leave behind. In the rare case of a ...

Scientists call it a meteoroid stream, but until now had little clue as to how an asteroid—which are comprised of rock and metal—could produce one. New research published today in the ...

CFD is performed using LeMANS, which solves the Navier-Stokes equations for hypersonic flow in thermochemical nonequilibrium. Entry of a meteoroid into the atmosphere is followed by ablation of the ...
