Solar scientists have found tiny, short-lived jets of energy on our sun to be the primary drivers of the solar wind, marking a step toward better understanding our sun's elusive behavior ...

This may explain the strange properties of the orbits of our solar system's planets ... theoretical astrophysics has long been to figure out how the orbits later became out-of-round and tilted ...

PG&E announced a planned 65 percent rate hike over the next three years, inspiring me to get a quote on installing solar panels.
