The Breathtaking Power And Beauty Of The Sun
We know our sun is vast and blazing. But sometimes it’s blazing more aggressively than others. Positively storming. Last week, the largest solar storm in almost a decade boomed out with a wave of cosmic energy across the 93 million miles to Earth. And we got hit.
Superheated gas hurling waves of particles off the sun. Slamming Earth’s magnetic field. Threatening power grids, orbiting satellites, GPS signals, airline flights, radio communications. And making some amazing Northern Lights.

Simon Critchley: To Philosophize is to Learn How to Die
English philosopher Simon Critchley, chair and professor of Philosophy at The New School for Social Research, discusses his 2009 New York Times bestseller, The Book of Dead Philosophers.
Starting with Cicero’s axiom, "To philosophize is to learn how to die," Professor Critchley leads us to his conclusion that to die is to learn how to live. The Daily Telegraph called the book "rigorous, profound, and frequently hilarious" and described Critchley as "an engaging and deadpan guide to the metaphysical necropolis" as well as "bracingly serious and properly comic."
