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.
Meteorite isotopes, meteorite paleomagnetics, and planet formation models collectively show Jupiter formation via first slow then fast collection of material by core accretion in
Chemical compositions of rocks from Mars indicate that the earliest orbits of Jupiter and Saturn were more circular than they are today.
A new tool to measure the magnetic signatures of big meteorites could not only aid NASA’s mission to Psyche; it could also help solve mysteries about how magnetic fields formed in our early solar system.
A layer of nickel of cosmic origin, which exists between 80 and 110 km high in Earth’s atmosphere, has been modeled for the first time, including dynamics and complex neutral and ion chemistry.
Fireballs in the summer sky may signify a chance to probe their mysterious origin.
Rare 2-million-year record reveals the meteorite flux rate.
