Analysis of a meteorite that fell in Costa Rica shows that its parent body may resemble the asteroid Bennu.
New research supports the hypothesis that dinosaurs were done in by climate change after an asteroid impact kicked up a massive plume of sulfur gases that circled the globe for several decades.
A team of scientists, educators, and teenagers discovered the objects, some of which may have been delivered by a fireball that streaked across the sky in 2017.
Analysis of the Chassigny meteorite suggests the planet acquired most of its interior volatiles from meteorites, not from the solar nebula.
A new method, nano-FTIR, is used to examine microstructures and processes on grains, displaying its benefit for examining asteroid returned samples through a meteorite.
To trace how crucial ingredients for life arrived at Earth, scientists track noble gases. Now, improved methods are drawing new clues from krypton, the most cryptic of noble gases.
By analyzing rare Martian meteorites, researchers have uncovered a crystalline structure created by a large asteroid or comet impact that potentially affected the Red Planet’s habitability.
A new algorithm suggests that only a small fraction of meteorites present on the White Continent’s surface have been recovered to date.
Organic molecules on a Martian meteorite have fueled nearly 30 years of scientific debate. New evidence suggests they were formed by Martian processes, offering more support for a once habitable environment on the Red Planet.
By using data from two lightning-spotting satellites, researchers measure explosions of thousands of small meteors and create a database that could help the planetary defense community.
