The 11-year solar cycle continues during prolonged sunspot minima

Streaming into the solar system at nearly the speed of light, galactic cosmic rays (GCRs) are a high-energy mix of protons, electrons, and atomic nuclei. As they pass into reach of the outflowing solar wind, the propagation ...

Scientists use molecular layers to study nanoscale heat transfer

Scientific research has provided us with a fundamental understanding of how light (via photons) and electricity (via electrons) move within and between materials at the micrometer or nanometer levels, making possible a wide ...

New type of cosmic ray discovered after 100 years

(Phys.org)—Using the European X-ray astronomy satellite XMM-Newton, researchers from CNRS and CEA have discovered a new source of cosmic rays. In the vicinity of the remarkable Arches cluster, near the center of the Milky ...
