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.
Typical paleomagnetic measurements average a sample’s signal. The quantum diamond microscope helps scientists make micrometer-scale maps of magnetism, showing where a sample locked in its magnetic signatures.
South Africa’s Vredefort impact structure is the largest on the planet, and researchers have now discovered the first proximal ejecta possibly deriving from the cataclysmic impact.
Researchers working in Chile’s Atacama Desert have collected thousands of “atacamaites” that suggest a meteorite struck the region roughly 8 million years ago.
Researchers dissolve chunks of the ancient seafloor to trace Earth’s impact history and find that colossal clashes between asteroids don’t often trigger an uptick in meteorite strikes.
