Nanoparticles found in moon glass bubbles explain weird lunar soil behaviour
phys.org said:
A stunning discovery by Queensland University of Technology soil scientist Marek Zbik of nanoparticles inside bubbles of glass in lunar soil could solve the mystery of why the moon's surface topsoil has many unusual properties.
Dr Zbik, from Queensland University of Technology's Science and Engineering Faculty, said scientists had long observed the strange behaviour of lunar soil but had not taken much notice of the nano and submicron particles found in the soil and their source was unknown.
Dr Zbik took the lunar soil samples to Taiwan where he could study the glass bubbles without breaking them using a new technique for studying nano materials call synchrotron-based nano tomography to look at the particles. Nano tomography is a transmission X-ray microscope which enables 3D images of nanoparticles to be made.
"We were really surprised at what we found," Dr Zbik said.
"Instead of gas or vapour inside the bubbles, which we would expect to find in such bubbles on Earth, the lunar glass bubbles were filled with a highly porous network of alien-looking glassy particles that span the bubbles' interior.
