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 ...

Approximately 4.6 billion years ago, our solar system formed from a huge disk of gas and dust orbiting our sun. The asteroids seen today are some of the most complete artifacts of this formation that ...

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 look up at the night sky, we tend to see asteroids as simple, wandering rocks—the leftover debris from the birth of our solar system. However, these celestial travellers are far from uniform.

Space is full of treasures. Literally. If we were able to extract the resources from the rocks in the asteroid belt alone, we ...

NASA says five notable asteroids will safely pass Earth in the second half of 2026, helping scientists improve asteroid tracking and strengthen planetary defense.

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?

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 ...
