The Sun, the giant star that allows life to flourish on our planet. So large, that one million of our earth's, would easily fit inside its mass. At 4.6 billion years old, it will eventually burn itself out...in about 5 billion years. Nothing we have to worry about...unless...in 48 hours, the Earth will be hit by a Coronal Mass Ejection (CME) from the Sun, a "Carrington Event" that has the power to shut down and possibly destroy the world's electrical infrastructure. To try and prevent permanent damage, everything goes dark prior to the hit: global communications are shut down; hospital emergency generators are disconnected; the entire internet, media broadcasting, and cell phone systems are turned off.

The big question? What would you do if you only had 48 hours to live?
