This water flow occurred on an ancient asteroid more than one billion years after its formation and was probably triggered by an impact that generated...
Tektites are nearly pure glasses (practically no crystalline inclusions) created when a space rock slams into Earth, melting surface material and hurling...
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...
The first bodies to form in the Solar System acquired their materials from stars, the presolar molecular cloud and the protoplanetary disk. Asteroids that...

The Vera C. Rubin Observatory is a major new scientific facility jointly funded by NSF and the U.S. DoE’s Office of Science. The new images are a small...
Vesta, the second largest asteroid in our Solar System, has not experienced full differentiation into a metallic core, silicate mantle and basaltic crust,...
An asteroid called Donaldjohanson was captured by NASA’s Lucy spacecraft during a flyby on April 20, 2025. At closest approach, the spacecraft came within...
Astronomers using the Gemini Multi-Object Spectrograph (GMOS) on the Gemini South telescope have determined that the recently-discovered near-Earth asteroid...
The destructive power of an impacting asteroid is primarily estimated by knowledge of its size. The near-Earth asteroid 2024 YR4 reached a peak 2032 impact...
Astronomers from SETI Institute, NASA’s Ames Research Center and Curtin University have traced the impact orbit of 75 observed meteorite falls to several...
A team of geologists from Curtin University has discovered unequivocal evidence for a hypervelocity meteorite impact 3.47 billion years ago (Archean Eon)...
A near-Earth asteroid called 2024 YR4 has been closely monitored in the past couple of months as its odds of impacting Earth in 2032 rose to around 3%....
NASA’s Lucy spacecraft will fly by the small asteroid Donaldjohanson on April 20, 2025.
