What can we learn from sending codependent bacteria and plants into space? Quite a bit, it would appear. An experiment with the tongue-twisting name Symbiotic Nodulation in a Reduced Gravity Environment, or SyNRGE for short, could yield benefits on Ear…

Over the July 14-15, 2012 weekend and through the early morning of July 16, Earth experienced what’s called a geomagnetic storm, which happens when the magnetic bubble around Earth, the magnetosphere, quickly changes shape and size in response to incom…

Scientists have long believed that comets and, or a type of very primitive meteorite were the sources of early Earth’s volatile elements. Understanding where these volatiles came from is crucial for determining the origins of both water and life. New r…
