We aim to compute the impact rates for objects with a diameter of 1 km onto the regular satellites of Jupiter, Saturn and Uranus using our latest dynamical simulations of […]
Comets and Asteroids
Characterization of (98943) 2001 CC21, the Target of Hayabusa2#
The near-Earth asteroid (98943) Torifune, previously designated 2001 CC21, is the flyby target of the Hayabusa2 extended mission, nicknamed Hayabusa2# (SHARP: Small Hazardous Asteroid Reconnaissance Probe).
The Refractory-to-ice ratio in Comet 67P: Implications on the Composition of the Comet-forming Region of the Protoplanetary Disk
Comets, asteroids, and other small bodies are thought to be remnants of the original planetesimal population of the Solar System. As such, their physical, chemical, and isotopic properties hold crucial […]
Life’s Building Blocks Discovered In Samples From Asteroid Bennu
Japanese collaborators detected all five nucleobases — building blocks of DNA and RNA — in samples returned from asteroid Bennu by NASA’s OSIRIS-REx mission.
Pristine Asteroid Samples Reveal Secrets Of The Ancient Solar System
Curtin University researchers have gained an unprecedented glimpse into the early history of our solar system through some of the most well-preserved asteroid samples ever collected, potentially transforming our understanding […]
Exploring The Mysteries Of Asteroid Bennu
During the past year, there’s been an unusual set of samples at the Department of Energy’s Lawrence Berkeley National Laboratory (Berkeley Lab): material gathered from the 4.5-billion-year-old asteroid Bennu when […]
Dust From asteroid Bennu: Building Blocks Of Life And Possible Habitats Were Widespread In Our Solar System
It took two years for NASA’s OSIRIS-REx space probe to return from asteroid Bennu before dropping off a small capsule as it flew past Earth, which was then recovered in […]
Traces Of Ancient Brine Discovered On Asteroid Bennu Contain Minerals Crucial To Life
A new analysis of samples from the asteroid Bennu, NASA’s first asteroid sample captured in space and delivered to Earth, reveals that evaporated water left a briny broth where salts […]
Asteroid Bennu Sample Reveals A Mix Of Life’s Ingredients
Studies of rock and dust from asteroid Bennu delivered to Earth by NASA’s OSIRIS-REx (Origins, Spectral Interpretation, Resource Identification and Security–Regolith Explorer) spacecraft have revealed molecules that, on our planet, […]
Mass of Particles Released by Comet 12P/Pons-Brooks During 2023-2024 Outbursts
During its most recent return, comet 12P/Pons-Brooks experienced 14 well-documented outbursts, observed between June 13, 2023, and April 2024, at heliocentric distances ranging from 4.26au to 0.85au.
