The massive asteroid that buzzed Earth on Monday didn't come alone. Scientists working with NASA's Deep Space Network antenna found that the asteroid was so large that it had its own small moon.
You wouldn't think our planet experiences many close encounters from asteroids. Yet a new map shows exactly how often Earth's atmosphere is hit by small asteroids, called bolides.
It turns out that the asteroid Vesta may have a history of large impacts. Scientists have completed the first geological and tectonic map of the asteroid, revealing a bit more about its past.
Astronomers have discovered a new active asteroid within our solar system. Called 62412, the asteroid is located in the main asteroid belt between Mars and Jupiter, and is the very first comet-like objects seen in the Hygiea family of asteroids.
Scientists may have found out how Vesta became shaped like it is. Using computer models to simulate collisions on Vesta, scientists have found out how Vesta may have gotten the deep grooves that encircle its midsection.
NASA's Spitzer Space Telescope may have just spotted the remains of a collision between large asteroids. It's found an eruption of dust around a young star with particles that could eventually lead to the formation of planets.
Scientists may have just made a discovery that could protect our planet from future collisions with asteroids.
Scientists are learning a bit more about the violent history of our solar system. By studying a unique volcanic meteorite recovered from Western Australia, scientists have found out that a series of collisions of asteroids occurred more than 3.4 billion years ago.
Scientists are learning a little bit more about the asteroid, Vesta, and its internal structure. With the help of numerical simulations and data from the space mission Dawn, researchers have taken a closer look at its internal structure.
While space may seem empty, it's not. Instead, it flows with electric activity that may be able to impact space missions. Now, NASA wants to learn a bit more about the electrical environment of space as they begin plans to send humans to a nearby asteroid.
Scientists involved with the NASA Asteroid Initiative have announced that small asteroids can actually be flying rock clusters or even clouds of dust surrounding solid rocks.
When you think of threats to cities and towns, your mind might automatically go to the problem of crime or even climate change. Yet there may be another threat that we haven't considered: asteroid impacts.
