By analyzing nickel isotopes preserved in the 66-million-year-old debris left by the Chicxulub impact, researchers conclude that the asteroid responsible...
The main-belt asteroid Donaldjohanson, a heavily cratered fragment born from a catastrophic breakup 155 million years ago, appears to wobble through space...
Planetary scientists analyzing a lunar meteorite known as Northwest Africa (NWA) 12593 have uncovered evidence of an asteroid impact that occurred 3.5...
The new Polana collisional family in the Solar System’s main asteroid belt is the hypothesized origin of the near-Earth asteroids (101955) Bennu, which...
NASA’s Lucy mission continues to analyze images collected during the spacecraft’s April 20, 2025 encounter with the carbonaceous asteroid Donaldjohanson.
