An international team of researchers working at a research site situated a mile and a half below China's Jinping Mountains, has found via experimentation, a likely explanation for the high concentrations of calcium seen in ...
When a star explodes (a supernova), it sends its intense burst of light out in all directions. On rare occasions, in the months and years that follow, rings of light or "light echoes" spread out from the original supernova ...
