The star named KIC 8462852 is so unusual -- one scientist even suggested it could be our first sign of a hypothetical alien megastructure called a Dyson Sphere. *The world’s first interplanetary mining mission It’s not the Nostromo made famous in the movie Alien, but the world’s first commercial interplanetary mining mission will launch a precursor flight next year before venturing off in to deep space to mine a near Earth asteroid. Australia changing its address *Australia is about to change its address. Federal government hasn’t updated the continent’s coordinate system since 1994.causing existing GPS navigation systems to be off by about one and a half metres. *New project to study dark energy The United States

The finding is expected to help researchers solve one of the greatest mysteries in biology -- the origin of homochirality -- and offer insights into what we can expect from life throughout the universe. *New ideas on the nature of black holes A team of scientists have developed a new way of looking at the physics of black holes. The hypothesis suggests that matter might in fact survive its foray into these space objects and come out the other side. *The most dangerous threat to humanity to provide the best meteor shower in almost 20 years This year’s Perseids meteor shower is set for its best show in nearly 20 years. Around 150 meteors an hour expected to delight sky watchers at its peak on the night

The findings provide new insights into the evolution of the Milky Way. *Mapping exotic matter inside neutron stars Scientists have opened a new window into the mystery of what lies inside neutron stars. Ultimately, the research may answer the question, whether neutron stars are composed solely of ordinary atomic nuclei, or if they contain more exotic dense de-confined quark matter. *Australian satellites being space tested prior to launch Researchers from around Australia have begun testing satellites at the Australian National University Mount Stromlo space testing facilities ahead of a mass satellite launch from the International Space Station later this year. They will be launched int

The discovery helps scientists better understand how the Milky Way was formed and how it’s evolved ever since. *New questions about how gullies are formed on Mars A new study claims liquid water flowing over the surface of Mars isn’t responsible for the recent formation of gullies on the red planet. The new findings are based on data from NASA’s Mars Reconnaissance Orbiter spacecraft which shows no mineralogical evidence for abundant liquid water or its by-products associated with the gullies. *Huge fire ball was space junk A huge fireball seen burning up in the night skies over Las Vegas was most likely Chinese space junk rather than a meteor. Large regions

Scientists had thought this enormous reservoir of hot gas remained stationary while the Milky Way spins inside it. *The Square Kilometer Array reaches another milestone Scientists have completed another key step in their efforts to build what will be the world’s largest radio telescope, the SKA or Square Kilometer Array. Researchers have successfully tested astronomical verification of a critical sub-system for the giant telescope known as the frequency synchronisation system. *Farewell to Rosetta’s Philae lander European Space Agency mission managers have formally switched off the system on the Rosetta spacecraft which provides communications links between the orbiter and its tiny Phi

The impact – which occurred about 3.46 billion years ago -- is the second oldest dated collision in the planet’s history. Why galaxies stop making stars A new study has determined why galaxies stop making new generations of stars. Astronomers found two separate processes are involved in ending star formation. The hunt for dark matter continues following another failed search for the elusive particle A 20 month long search for a mysterious particle which makes up 80 percent of all the matter in the universe has failed to uncover the elusive identity of dark matter. The Large Underground Xenon dark matter experiment yielded no trace of a candidate particle despite the most sensitive search even conducted. A n

Hi...Stuart with the Show Notes for Series 19 Episode 48.   *A bounty of Brown Dwarfs and planets discovered deep in the Orion Nebula New technology allowing astronomers to peer deeper into the heart of the Orion Nebula than ever before, has revealed a massive population of previously unseen planets and brown dwarfs. The discovery shows that the Orion Nebula may be forming proportionally far more low-mass objects than closer and less active star formation regions. *Astronomers produce the most detailed map yet of the visible universe. Astronomers have produced the largest-ever, three-dimensional map yet of the visible universe -- showing some 1.2 million galaxies -- covering over a quarter of the sky and mapping out the structure of the universe over a volume of 650 cubic billion light-years. The new map allows scientists to make the best measurements so far of the effects of a mysterious force called dark energy on the expansion of the universe and consequently the ultimate fate of the cosmos. *Astronomers d

Hi...Stuart with the Show Notes for Series 19 Episode 47 *Ancient supernovae affected life on Earth Two ancient supernovae which erupted within 300 light years of Earth likely exposed biology on our planet to a long-lasting cosmic radiation. The findings are based on new computer simulations of the impact the two exploding stars had on surrounding space. *Solving the mystery of the Martian moons Astronomers may have finally solved the mystery of how the two Martian moons -- Phobos and Deimos -- were formed. Two separate and independent studies have both concluded that the moons were formed by collision events early in the red planet’s history. *Newly discovered planet has three Suns If you thought Luke Skywalker’s home planet, Tatooine, was a strange world with its two Suns in the sky, imagine a planet where you’d either experience constant daylight or enjoy triple sunrises and sunsets every day. This isn’t the opening scene for some future episode of Star Wars but rather the vista seen from the surface of th

Hi .... Stuart with the Show Notes for Series 19 Episode 46: *First evidence explaining how supermassive black holes are formed Astronomers have discovered evidence for an unusual kind of black hole which would have been born in the very early universe and could have been the seeds for today’s supermassive black holes. While astronomers have a good handle on how stellar mass black holes are formed – mystery has always surrounded their larger counterparts -- the supermassive black holes found at the centre of most if not all galaxies. Special guest....Aaron Smith from University of Texas, Austin. *New dwarf planet discovered beyond Neptune It’s not the long sort after mysterious planet 9 – but a new dwarf planet has been discovered orbiting the Sun beyond Neptune.Astronomers spotted the distant frozen world using the Canada-France-Hawaii Telescope on Mauna Kea. The new object -- designated 2015 RR245 is about 700 kilometres in diameter and has one of the largest orbits of any known dwarf planet. *Rosetta’s mis

Hi, Stuart with the Show Notes for Series 19 Episode 45... *Citizen scientists discover a massive galaxy cluster Two volunteer participants in an international citizen science project have discovered a rare galaxy cluster which has now been named in their honour. The pair pieced together the huge C-shaped structure -- located some 1.2 billion light years away -- from much smaller images of cosmic radio waves shown to them as part of the web-based Radio Galaxy Zoo project. *New Type of Meteorite Linked to Ancient Asteroid Collision Scientists have discovered a new type of meteorite never before seen on Earth. The space rock, appears to be from the missing partner in a massive asteroid collision 470 million years ago. *Physicists discover family of tetraquarks Physicists have confirmed the existence of a new group of sub atomic particles called tetraquarks. Scientists at Syracuse University confirmed the existence of the rare exotic particle as well as three siblings using the Large Hadron Collider beauty LHCb
