Southern Illinois, and across the US

All of North America will enjoy a total eclipse of the sun on August 21, 2017. Those in the path of totality, where the moon completely covers the face of the sun and only the corona is visible, will experience a total solar eclipse–temperatures will suddenly drop, and wildlife will go eerily silent. This path of totality will stretch from Salem, Oregon to Charleston, South Carolina.

Everything we see today, our precious atoms and molecules, got here by traveling on swaths of dark matter. From the oscillations of the hot plasma of the primordial universe, to the formation and dynamics of modern galaxies, dark matter plays a necessary role. The very construct in which we sit is defined by its abundance. Our universe’s evolution is controlled tightly by a cosmic tug-of-war between dark matter and dark energy. Read more…
