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...
How did the molecular building blocks for life end up on Earth? One long-standing theory is that they could have been delivered by comets. Now, researchers...
Every year, our planet encounters dust from comets and asteroids. These interplanetary dust particles pass through our atmosphere and give rise to shooting stars. Some of...
Lightning strikes were just as important as meteorites in creating the perfect conditions for life to emerge on Earth, geologists say. Minerals delivered to Earth in...
After traveling several billion miles toward the Sun, a wayward young comet-like object orbiting among the giant planets has found a temporary parking place along the...
It was tens of miles wide and forever changed history when it crashed into Earth about 66 million years ago. The Chicxulub impactor, as it’s known,...
