Each December, meteors streak across the sky as part of the massive Geminid meteor shower, with up to about 120 meteors visible per hour at the shower’s peak. This reliable yearly show is a popular ...

In two separate studies, researchers identify nucleosynthetic isotope anomalies in the volatile elements potassium (K) and zinc (Zn) in meteorites, which constrain the origins of the material that ...

They found that around half the Earth's inventory of the volatile element zinc came from asteroids originating in the outer Solar System -- the part beyond the asteroid belt that includes the planets ...

How a planet comes together has implications for whether it captures and retains the volatile elements, including nitrogen, carbon and water, that eventually give rise to life, according to scientists ...

For many years, scientists have predicted that many of the elements that are crucial ingredients for life, like sulfur and nitrogen, first came to Earth when asteroid-type objects carrying them ...

Washington, D.C.–Tiny variations in the isotopic composition of silver in meteorites and Earth rocks are helping scientists put together a timetable of how our planet was assembled beginning 4.568 ...

For years, scientists have puzzled over why Earth and Mars are missing certain key elements. Now, a fresh study suggests these ingredients weren’t missing from the start. Instead, they were likely ...
