More space technology must be developed to prevent "city-killing asteroids" from hitting Earth, experts recommended at a recent science conference. While the risk is low, mid-size asteroids near Earth ...

In the vast expanse of space, an estimated 1 million Near Earth Objects (NEOs), also known as near-Earth asteroids, are constantly orbiting close to our planet. Every night, astronomers track NEOs and ...

Asteroids are some of the oldest objects in the Solar System: leftovers from the chaotic time when planets were assembling from dust and rock. They’re time capsules, preserving clues about what the ...

Asteroids are small rocky bodies that travel around the Sun. They are much smaller than planets. They are very important because they can give us clues about the early composition of the Solar System.

Scientists studying asteroids found that two seemingly unrelated types share a strange dusty coating of troilite. By using polarization of light instead of traditional spectra, they uncovered evidence ...

When we think about asteroids that could threaten Earth, we often imagine massive, city-sized rocks hurtling through space. But what if the real danger comes from much smaller, barely detectable ones?

A study of thousands of space rocks may explain why a common type in space is so uncommon on our planet. Reading time 2 minutes Earth’s meteorite collection just got called out for being a little ...

The cars, cellphones, computers and televisions that people in the U.S. use every day require metals like copper, cobalt and platinum to build. Demand from the electronics industry for these metals is ...

In late 2024, astronomers spotted asteroid 2024 YR4 on a trajectory that could potentially threaten Earth. This observation triggered a fervid series of observations of the object — possibly as big as ...
