The cool glow of star formation: First light of powerful new camera on APEX
A new instrument called ArTeMiS has been successfully installed on APEX—the Atacama Pathfinder Experiment. APEX is a 12-metre diameter telescope located high in the Atacama Desert, which operates at millimetre ...
Device that can manipulate radiofrequency signals could soon reduce size of short-distance communication systems
Millimeter waves are a type of radiofrequency electromagnetic radiation with wavelengths between 0.1 and 10 millimeters long. Because they are susceptible to absorption by water in the atmosphere, they travel ...
