The Sun Unleashes Coronal Mass Ejection At Earth 220

astroengine writes "Yesterday morning, at 08:55 UT, NASA's Solar Dynamics Observatory detected a C3-class flare erupt inside a sunspot cluster. 100,000 kilometers away, deep within the solar atmosphere (the corona), an extended magnetic field filled with cool plasma forming a dark ribbon across the face of the sun (a feature known as a 'filament') erupted at the exact same time. It seems very likely that both eruptions were connected after a powerful shock wave produced by the flare destabilized the filament, causing the eruption. A second solar observatory, the Solar and Heliospheric Observatory, then spotted a huge coronal mass ejection blast into space, straight in the direction of Earth. Solar physicists have calculated that this magnetic bubble filled with energetic particles should hit Earth on August 3, so look out for some intense aurorae — a solar storm is coming."

Submission + - Researchers Show Names are Weak Passwords (lightbluetouchpaper.org)

Sub Zero 992 writes: Security researchers at Cambridge University have analysed Facebook's gigantic list of human names. We have known for many years that using password recovery questions such as "What is your pet's name?" are weak alternatives to real security. So the question is, what will replace passwords as authentication tokens?
