When NASA’s Lucy spacecraft flew past its first official target Dinkinesh in November 2023, researchers discovered that the asteroid — known as “Dinky” — was not...
Samples reveal evidence of changes experienced by the surface of asteroid Ryugu, some probably due to micrometeoroid bombardment. Analyzing samples retrieved from the asteroid Ryugu by...
Using artificial intelligence, satellite observations, and climate model projections, a team of researchers from Switzerland and Belgium calculate that for every tenth of a degree of...
A new study is shaking up what scientists thought they knew about distant objects in the far reaches of the solar system, starting with an object...
Sound waves thought to be from a 2014 meteor fireball north of Papua New Guinea were almost certainly vibrations from a truck rumbling along a nearby...
Analysis of organic compounds — calledpolycyclic aromatic hydrocarbons (PAHs) — extracted from the Ryugu asteroid and Murchison meteorite has foundthat certainPAHs likely formed in the cold...
The asteroid that causes the Geminid shooting star swarm has also puzzled researchers with its comet-like tail. The infrared spectrum of rare meteorites helped to determine...
