Astrophiz 31 is out now on iTunes and Soundcloud. Our feature interview is with Dr Elisabetta Barberio who explains a new Dark matter Experiment deep in a goldmine in South Eastern Australia. Elisabetta is a member of the Experimental Particle Physics Group at the University of Melbourne. Previously, she was a staff researcher at CERN, the European laboratory of Particle Physics. She was involved with data analysis in the OPAL experiment at the Large Electron Positron Collider at CERN, and has worked on the Higgs Boson and ATLAS, which is a particle physics experiment at the Large Hadron Collider (LHC) at CERN. Dr Ian Musgrave in our regular feature, ‘What’s up Doc?’ tells us what to look for in the night sky this week using naked eye, binoculars or telescopes, and Jupiter is ruling our skies. In the news: Dr Brad Tucker and ANU astronomers launch a Citizen Science project and public search of the southern skies for the elusive 'Planet Nine’ using data from the Skymapper telescope at Siding Springs in Australia. 2.The largest magnetic fields ever found in the universe are caused by collisions between immense galaxy clusters, and these giant magnetic fields are millions of light years across and 100 times larger than the Milky Way. 3. How to hunt for a black hole with a telescope the size of Earth. How do you photograph a black hole? Impossible you say? Inventive researchers have plans to do exactly that, and hope to grab the first images of an event horizon — the point of no return from the black hole at the centre of our Milky Way. 4. Using the Australian AAOmega+2dF Spectrograph and the Southern African Large Telescope astronomers have just discovered one of the most massive superclusters in the universe hiding behind the Milky Way in the constellation of Vela. This is a massive group of several galaxy clusters, each one containing hundreds or thousands of galaxies. The researchers estimate that this Vela supercluster could contain somewhere between 1,000 and 10,000 trillion stars. Their calculations also show Vela is about 800 million light-years distant and zooming farther and farther away from us at a speed of about 40 million mph (18,000 kilometers per second).

      For Dad He would have loved this       Tutankhamun (alternatively spelled with Tutenkh-, -amen, -amon) was an Egyptianpharaoh of the 18th dynasty (ruled ca. 1332 BC – 1323 BC in the conventional chronology), during the period of Egyptian history known as the New Kingdom. He is popularly referred to as King Tut. His original name, Tutankhaten, means "Living For Dad he would have loved this Go to   According to the September 2010 issue of National Geographic magazine, Tutankhamun was the result of anincestuous relationship and, because of that, may have suffered from several genetic defects that contributed to his early death.[19] For years, scientists have tried to unravel ancient clues as to why the boy king of Egypt, who reigned for 10 years, died at the age of 19. Several theories have been put forth; one was that he was killed by a blow to the head, while another was that his death was caused by a broken leg.      Lord Carnarvon was an enthusiastic amateur Egyptologist, undertaking in 1907 to sponsor the excavation of nobles' tombs in Deir el-Bahri (Thebes). Howard Carter joined him as his assistant in the excavations.[5] It is now established that it was Gaston Maspero, then Director of the Antiquities Department, who proposed Carter to Lord Carnarvon.[6] He received in 1914 the concession to dig in theValley of the Kings, in replacement of Theodore Davis who had resigned. In 1922, he and Howard Carter together opened the tomb of Tutankhamun in the Valley of the Kings, exposing treasures unsurpassed in the history of archaeology.     Lord C                    Howard Carter     RADAR   for RAdio Detection AndRanging.[1] The term radar has since entered English and other languages as the common noun radar, losing all capitalization.   James Clerk Maxwell FRS FRSE (13 June 1831 – 5 November 1879) was a Scottish[1][2]mathematical physicist.[3] His most prominent achievement was to formulate a set of equations that describe electricity, magnetism, and optics as manifestations of the samephenomenon, namely the electromagnetic field.[4] Maxwell's achievements concerning electromagnetism have been called the "second great unification in physics",[5] after the first one realised by Isaac Newton.     The first permanent colour photograph, taken by James Clerk Maxwell in 1861James Clerk Maxwell FRS     Heinrich Rudolf Hertz (22 February 1857 – 1 January 1894) was a German physicist who clarified and expanded James Clerk Maxwell's electromagnetic theory of light, which was first demonstrated by David Edward Hughes using non-rigorous trial and error procedures. Hertz is distinguished from Maxwell and Hughes because he was the first to conclusively prove the existence of electromagnetic waves by engineering instruments to transmit and receive radio pulses using experimental procedures that ruled out all other known wireless phenomena.[1] The scientific unit of frequency – cycles per second – was named the "hertz" in his honor.[2]     Guglielmo Marconi     for his development of Marconi's law and a radio telegraph system. Marconi is often credited as the inventor of radio, and he shared the 1909 Nobel Prize in Physics with Karl Ferdinand Braun "in recognition of their contributions to the development of wireless telegraphy".[2][3][4] As an entrepreneur, businessman, and founder of the The Wireless Telegraph & Signal Company in Britain in 1897, Marconi succeeded in making a commercial success of radio by innovating and building on the work of previous experimenters and physicists.[5][6] In 1924,   12 December 1901, using a 152.4-metre (500 ft) kite-supported antenna for reception, the message was received atSignal Hill in St John's, Newfoundland(now part of Canada) signals transmitted by the company's new high-power station at Poldhu, Cornwall. The distance between the two points was about 3,500 kilometres (2,200 mi). Heralded as a great scientific advance, there was—and continues to be—considerable skepticism about this claim Feeling challenged by skeptics, Marconi prepared a better organized and documented test. In February 1902, the SS Philadelphia sailed west from Great Britain with Marconi aboard, carefully recording signals sent daily from the Poldhu station. The test results producedcoherer-tape reception up to 2,496 kilometres (1,551 mi), and audio reception up to 3,378 kilometres (2,099 mi). The maximum distances were achieved at night, and these tests were the first to show that for mediumwave and longwave transmissions, radio signals travel much farther at night than in the day   Robert Watson-Watt     Sir Robert Alexander Watson-Watt, KCB, FRS, FRAeS (13 April 1892 – 5 December 1973) was a pioneer and significant contributor to the development of radar. Radar was initially nameless and researched elsewhere but it was greatly expanded on 1 September 1936    This system provided the vital advance information that helped the Royal Air Force win the Battle of Britain.[2][1]     Higgs boson           Peter  Higgs still teaching             The Higgs boson or Higgs particle is an elementary particle initially theorised in 1964,[6][7] and tentatively confirmed to exist on 14 March 2013.[8] The discovery has been called "monumental"[9][10] because it appears to confirm the existence of the Higgs field,[11][12] which is pivotal to the Standard Model and other theories within particle physics. It would explain why some fundamental particles have mass      The LHC tunnel is located 100 metres underground, in the region between the Geneva International Airport and the nearby Jura mountains. It uses the 27 km circumference circular tunnel previously occupied by LEP which was closed down in November 2000. CERN's existing PS/SPS accelerator complexes will be used to pre-accelerate protons which will then be injected into the LHC. The LHC resumed operation on Friday 20 November 2009 by successfully circulating two beams, each with an energy of 3.5 trillion electron volts. The challenge that the engineers then faced was to try to line up the two beams so that they smashed into each other. This is like "firing two needles across the Atlantic and getting them to hit each other"   http://www.youtube.com/watch?v=joTKd5j3mzk   3 minute video explains everything   Terracotta Army   Terracotta Army there were over 8,000 soldiers, 130 chariots with 520 horses and 150 cavalry horses, the majority of which are still buried in the pits near by Qin Shi Huang's mausoleum.[2] Other terracotta non-military figures were also found in other pits and they include officials, acrobats, strongmen and musicians. There are four main pits associated with the terracotta army.[24][25] These pits are located about 1.5 km east of the burial mound and are about 7 metres deep. The army is placed as if to protect the tomb from the east, where all the Qin Emperor's conquered states lay. Pit one, which is 230 metres long and 62 metres wide,[25] contains the main army of more than 6,000 figures.[26] Pit one has 11 corridors, most of which are over 3 metres wide, and paved with small bricks with a wooden ceiling supported by large beams and posts. This design was also used for the tombs of noblemen and would have resembled palace hallways. The wooden ceilings were covered with reed mats and layers of clay for waterproofing,      Some of these weapons such as the swords are still very sharp and found to be coated with chromium oxide. This layer of chromium oxide is 10–15 micrometre thick and has kept the swords rust-free and in pristine condition after 2,000 years       Graphene   Andre Geim: It's the thinnest material you can get -- it's only one atom thick. A tiny amount can cover a huge area, so one gram could cover a whole football pitch. It's the strongest material we are aware of because you can't slice it any further. Of course, we know that atoms can be divided into elementary particles, but you can't get any material that is thinner than one atom, or it wouldn't count as a material anymore. http://www.youtube.com/watch?v=dTSnnlITsVg http://www.youtube.com/watch?v=WFacA6OwCjA http://www.youtube.com/watch?v=sugmA-pll4k
