Sparks reportedly flew from telegraph machines, and the night sky turned an apocalyptic red, causing birds to chirp at what they thought was dawn.Today, scientists believe that in 1859, Earth collided with a massive number of electrically charged particles shot from the sun, all part of a coronal mass ejection. The episode became known as the Carrington Event, after the amateur ast ...read more

As a result, experts estimate that nearly a quarter of Americans aren't getting enough vitamin D.Despite its significance, questions remain: How much is enough? Can s ...read more
