Star Survivor: Companion Endures Explosion - Space.com  The starís existence confirms theories that supernovas can live with cosmic companions, yet still be friendly enough not to destroy their neighbors in the process. A massive object 100,000 times brighter than the Sun, the newfound star sits on ground zero of a known supernova and not only survived the explosion, but influenced the event and its stellar aftermath, researchers said.  
Theory: Mass Extinction by Our Own Sun - Space.com  The second-largest extinction in the Earth's history, the killing of two-thirds of all species, may have been caused by ultraviolet radiation from the Sun after gamma rays destroyed the Earth's ozone layer. Astronomers are proposing that a supernova exploded within 10,000 light years of the Earth, destroying the chemistry of the atmosphere and allowing the Sun's ultraviolet rays to cook fragile, unprotected life forms.   

Magnetic Bubbles In Space: A New Propulsion Concept? - SpaceDaily  Exploration of deep space requires new propulsion technologies that not only reduce travel time, but are cost effective and safe as well. One such proposed technology is based on the concept of a sail pushed along by space plasma.The basic ingredients of a plasma sail are a magnetic solenoid and a plasma machine aboard a spacecraft. The plasma machine must be capable of releasing a dense and warm plasma cloud. As the cloud expands, the magnetic field lines generated by the solenoid stretch out because of the diamagnetic nature of the plasma. This stretching creates a magnetic bubble, or balloon.
