*The source of the sky's X-ray glow* The sky is full of x-rays. There is a 50 year old mystery to be solved; where do all those x-rays come from? New research shows that the major source of the x-rays seen brightly in our skies originate in the local volume of space that the solar system swims in. The findings confirm the existence of a local hot bubble as the x-ray source, the space that encloses the solar system out to a distance of a few hundred light years from earth. There are no energetic stars within our bubble of space to produce all that energy. The next step for science is to find out how that power is produced and what generates it. We have an advantage in our understanding of such things. It is LENR pervasive throughout the interstellar medium providing us with our share of the dark matter and dark energy that fills the universe and it is the LENR that brightens our skies with all those x-rays.
