Astronomers classify near-Earth asteroids
Researchers determined the sizes, rotational speeds, and chemical compositions of 39 asteroids orbiting the Sun near Earth. Many were…
The fate of massive rotating stars
Researchers showed that massive stars at the end of their lives are more likely to collapse into black holes than to explode into…
How did Mars get its moons?
Astronomers calculated possible trajectories for small objects approaching Mars. They found that as many as 1 in 50 get captured in orbit,…
Astronomers model early star clusters
Scientists used computer simulations to determine how ancient star clusters formed. Their results were similar to real clusters found with…
Scientists observe a changing exoplanet orbit
Astronomers conducted a multifaceted study of the exoplanet TrES-1 b and found that its orbit is shifting, possibly due to an unseen…
