19 Yr Old Egyptian Girl, Aisha Mustafa, Invents New Quantum (Fuel-less) Space Propulsion System. Aisha's new system exploits the quirky laws of quantum physics which state that in spite of appearances, space really is not vacuum but that it is a seething cauldron of fundamental particle interactions involving creation and destruction of "virtual particles." http://www.thedailybleep.blogspot.com/2013/08/19-yr-old-egyptian-girl-aisha-mustafa.html
Humanity escapes the solar system: Voyager 1 signals that it has reached the edge of interstellar space
Voyager 1, which has been travelling at the rate of 10km/sec to the outer limits of the solar system since 1977, is now detecting the first traces of 'interstellar winds' (colder and slower than solar winds) - the signs it is finally reaching the edges of solar system. It is now 17,970,000,000 km - or 11,100,000,000 miles away.
