Anniversary of a cosmic blast
Five years ago today — on December 27, 2004 — the Earth was attacked
by a cosmic blast. It gets worse. This enormous wave of fierce energy was so powerful it actually partially ionized the Earth’s upper atmosphere, and it made the Earth’s magnetic field ring like a bell. Several satellites were actually blinded by the event. Story he http://blogs.discovermagazine.com/badastronomy/2009/12/27/anniversary-of-a-cosmic-blast/
