One more clue to the moon's origin

Humankind has maintained an enduring fascination with the moon. It was not until Galileo's time, however, that scientists really began study it. Over the course of nearly five centuries, researchers put forward numerous, ...

New model shows Earth's deep mantle was drier from the start

Earth's mantle is the thick layer of silicate rock between Earth's crust and its molten core, making up about 84% of our planet's volume. The mantle is predominantly solid but, on geologic time scales, it behaves as a viscous ...

Martian meteorite upsets planet formation theory

A new study of an old meteorite contradicts current thinking about how rocky planets like the Earth and Mars acquire volatile elements such as hydrogen, carbon, oxygen, nitrogen and noble gases as they form. The work is published ...

Scientists begin studying 50-year-old frozen Apollo 17 samples

Scientists at NASA's Goddard Space Flight Center in Greenbelt, Maryland, recently received samples of the lunar surface that have been curated in a freezer at NASA's Johnson Space Center in Houston since Apollo 17 astronauts ...

Opening a 50-year-old Christmas present from the moon

A pretty special gift unwrapping will soon take placeā€”a piercing tool built by ESA will open a moon soil container from Apollo 17 that has gone untouched for nearly 50 years. The opening will allow the extraction of precious ...

Meet VMS: The briefcase-sized chemistry lab headed to Venus

Short for Venus Mass Spectrometer, VMS is one of five instruments aboard the DAVINCI descent probe. Launching in 2029, DAVINCI will be the first US probe mission to enter Venus' atmosphere in over 40 years. The goal of the ...

Toward the scaling up of nanocages to trap noble gases

Over the past few years, scientists have demonstrated how cage-like, porous structures made of silicon and oxygen and measuring only billionths of a meter in size can trap noble gasses like argon, krypton, and xenon. However, ...

Solar wind from the center of the Earth

High-precision noble gas analyses indicate that solar wind particles from our primordial Sun were encased in the Earth's core over 4.5 billion years ago. Researchers from the Institute of Earth Sciences at Heidelberg University ...
