*New evidence supporting supernova shock wave theory of solar system's origins Astronomers have found more evidence supporting the longstanding theory that our solar system’s formation 4.6 billion years ago -- was triggered by a shock wave from an exploding supernova. The study based on evidence of the iron 60 isotopes in meteorites indicate that a supernova shock wave is still the most-plausible origin story for explaining the short lived radioactive isotopes in our Solar System

*A new window in the hunt for molecular signatures in deep space Astronomers have begun using one of the precursor radio telescopes for the Square Kilometre Array project to study molecular signatures which could lead to the detection of complex molecules that are precursors to life. The team are using the Murchison Widefield Array to undertake the observations focusing on the molecular gas and dust clouds from which new generations of stars are born.

*New clues about superluminous supernovae Astronomers have detected an extraordinarily bright supernova in a surprising location. This supernova discovery challenges current ideas of how and where such super-charged supernovas occur.

*Vega lofts two satellites on second launch this year An Arianespace Vega rocket has successfully launched two satellites into orbit. The mission blasted off into late night skies from the European Space Agency’s Kourou Space Port in French Guyana.

*Western fears grow as Iran and North Korea conduct illegal missile tests Sanctions have been placed on both North Korea and Iran after the two rogue nations carried out new missile tests over the past few weeks. Most attention has focused on North Korea which has carried out numerous missile tests in recent months the other member of the so-called axis of evil – Iran -- has also continued its own missile program with a launch on July 27th in breach of United Nations security council resolution 2231.

*The Science Report It may be too late to stop the planet heating up by two degrees, How drinking alcohol could improve your memory, A new expedition to an undersea continent east of Australia, New research into melanoma, How cats domesticated themselves – when they were ready.
