  • Earth in the supernova Kill Zone A new study claims the kill zone around a supernova could be as great as 50 light years – meaning any star that blew up within 50 light years of Earth could cause a mass extinction event. The study also found some tantalizing hints that even far more distant supernovae may have changed human evolution forever.

*Hundreds of new planets discovered Scientists using NASA's planet hunting Kepler space telescope have announced the discovery of hundreds of new exoplanets – planets orbiting stars other than the Sun. The 219 new exoplanetary candidates, brings the total number discovered by Kepler to a staggering 4 thousand and 34.

*Quark-gluon plasma detected during proton-proton collisions. Scientists studying collisions in the world’s largest atom smasher have detected hints of an extreme state of matter called a Quark Gluon plasma – some of the first material to form in the big bang 13.8 billion years ago. The observation is the first time Quark-Gluon plasma has been created through proton-proton collisions.

*Stratolaunch shows off its new mega aircraft Stratolaunch has shown off its new mega plane – a giant twin fuselage six engined aircraft designed to launch rockets into space. The 227 tonne aircraft has a wingspan of 117 metres and an all up take-off weight of 545 tonnes.
