SpaceTime with Stuart Gary

Hi everyone - Stuart here....and here's what's in this episode of SpaceTime: Hubble breaks cosmic distance record Astronomers have shattered the cosmic distance record by measuring the distance to the most remote galaxy ever seen in the Universe -- a stellar city that existed just 400 million years after the big bang 13.8 billion years ago. The amazing discovery was achieved by pushing the Hubble Space Telescope to its absolute limits. Scientists watch the Moon breath Researchers have watched the Moon's tenuous atmosphere -- known as an exosphere -- change depending on its exposure to the Sun and to meteor showers. The findings help astronomers better understand the physics of exospheres which are one of the most dominate types of atmospheres in the solar system. How Mars got its tilt A new study claims the surface of Mars was dramatically tilted around 3 to 3.5 billion years ago by a massive volcanic structure known as the Tharsis dome, which is the largest in the Solar System. Because of its extraordinary mass, the Tharsis dome caused the red planet’s crust and mantle to rotate around its core. The discovery of this huge shift changes our vision of Mars during the first billion years of its history, at a time when life may have emerged on the red planet. SpaceX finally flies on its fifth attempt After five launch attempts spanning almost two weeks a SpaceX Falcon 9 rocket has finally blasted off from the Cape Canaveral Air Force base in Florida, carrying the SES-9 telecommunication satellite into orbit. The Falcon 9 trailed a golden orange plume as it flew over the Atlantic Ocean carrying its Boeing built satellite into geostationary orbit.

In Episode 9: Fast Radio Burst mystery deepens Astronomers for the first time have detected repeating Fast Radio Bursts -- short bursts of radio waves from an enigmatic source located well beyond our Milky Way galaxy. Prior to this discovery, all previously detected Fast Radio Bursts have appeared to be one-off events. What if E.T. called us and nobody heard? As scientists step up their search for other life in the universe, two astrophysicists are proposing a way to make sure we don't miss the signal if extraterrestrial observers try to contact us first. The scientists say the best chance for us finding a signal from beyond is to presume that extraterrestrial observers are using the same methods to search for us that we are using to search for life beyond Earth. Asteroid close encounter Astronomers around the world will be counting down to the extremely close flyby of asteroid 2013 TX68 which could pass just 17,700 kilometres above the ground tomorrow March 5th. However, scientists admit they won’t know exactly how close the 35-metre-wide space rock will get until after the flyby occurs. ExoMars prepares for launch All systems are go for this month’s launch of the ExoMars 2016 spacecraft bound for the red planet. The joint Roscosmos and European Space Agency mission is slated to launch on a Russian Proton rocket from the Baikonur Cosmodrome in the central Asian republic of Kazakhstan on March 14. Where did the Martian moon Phobos come from? NASA scientists are closer to solving the mystery of how the Martian moon Phobos formed. NASA's Mars Atmosphere and Volatile Evolution spacecraft (MAVEN) has made a series of close approaches to the 28-kilometre-wide moon collecting data from within 500 kilometres of its surface. Expedition 46 crew return to Earth after record breaking space flight The Russian Soyuz TMA-18M capsule has returned safely to Earth carrying the expedition 46 crew from the International Space Station. Among those aboard the spacecraft as it touched down on the cold Kazakhstan steps was US astronaut Scott Kelly who set a new American record for long duration human space flight of 340 days in orbit.

Show Notes: The mystery of the IBEX ribbon Astronomers are a step closer to finally solving the mystery of the IBEX ribbon spotted at the edge of the solar system eight years ago. New computer simulations and data from NASA’s IBEX spacecraft are pointing to ionized solar wind particles streaming back into the solar system after interacting with interstellar space galactic magnetic fields. Invisible gas clouds appear shaped like dark noodles Astronomers have been given their best view yet of the giant interstellar gas clouds which make up a significant amount of the Milky Way galaxy’s matter. The invisible structures known as Extreme Scattering Events are high density lumps in the thin electrically charged gas between the stars in our Galaxy and appear to be shaped like noodles, lasagna sheets or possibly even hazelnuts. New Subatomic particle discovered Scientists at Fermilab have discovered a new particle—the latest member to be added to the exotic species of particles known as tetraquarks. The new discovery by the DZero experiment is of the first tetraquark candidate composed of four different quark flavours. Supernova puzzle close to being solved New observations using the Hubble Space Telescope have confirmed that a supernova which exploded more than three years ago is continuing to shine far brighter than expected. The supernova known as SN 2012cg could have important implications for astronomy’s ability to measure cosmic distances across the universe.

SpaceTime with Stuart Gary - Series 19 Episode 7 Source of mysterious Fast Radio Bursts finally identified Scientists have finally pinpointed the source of mysterious celestial events called Fast Radio Bursts. The strong pulse of radio waves lasting just millisecond was identified coming from an elliptical galaxy six billion light years away -- half way across the universe and back through time. Van Allen Radiation Belts are even stranger than imagined New data indicates the Earth’s Van Allen Radiation Belts could be very different in shape from what scientists have always thought. It seems the shape of the belts depends on what type of electron you’re looking at. Giant gas cloud explains galaxy’s missing “star forming” hydrogen Astronomers have discovered a spectacular plume of gas more than 300,000 light-years across streaming like the tail of a comet from a bright strange looking spiral galaxy. The massive hydrogen cloud is five times longer than the galaxy itself. Engineers working on new type of polar orbit Scientists are working to perfect a new type of satellite orbit which can keep a spacecraft above the north or south pole. The research is looking at how a satellite equipped with a large solar sail could partly offset gravity from both the Earth and the Sun with the slight but steady pressure of sunlight, allowing the spacecraft to hover above the Arctic or Antarctic, enabling continuous coverage of high-latitude regions for science and climate observation or for regional communication services.

In this episode....... Biggest known black hole discovered Astronomers have confirmed what could be the most massive black hole ever detected – a monster 21 billion times the mas of our Sun -- at the heart of a placid looking galaxy 300 million light years away. The record breaking supermassive black hole at the centre of the elliptical galaxy NGC 4889 in the Coma cluster, was detected in new images by the Hubble Space telescope. Five-dimensional black hole could 'break' general relativity Researchers have shown how a bizarrely shaped black hole could cause Einstein's general theory of relativity, a foundation of modern physics, to break down. However, the research also shows such an object could only exist in a universe with five or more dimensions. Pluto's surface is only ten million years old A new study claims Pluto's heart shaped Sputnik Planum region is only ten million years old -- far younger than the rest of the distant Kuiper Belt dwarf planet. The findings are based on a study of the number of impact craters detected on the frozen surface of Pluto by NASA's New Horizons spacecraft. Immense gas cloud to collide with the Milky Way Galaxy An immense gas cloud over 11 thousand light years wide is expected to slam into the Milky Way galaxy at over a million kilometres an hour. The cosmic collision which is expected to happen in about 30 million years from now, will spark a flurry of starburst triggering the formation of millions of new stars.

In this episode: Climate change showing Earth’s rotation A new study has confirmed that climate change caused by human activity such as burning coal, oil and other fossil fuels has both slowed Earth's rotation and caused a migration of the planet’s spin axis. A report in the journal Science Advances found the melting of glaciers caused by the world's rising temperatures has resulted in Earth's rotation slowing by about a thousandth of a second during the past century and the planet's rotational axis has been migrating at a rate of almost a centimeter per year. The aliens are silent because they’re dead A new study claims life on other planets would likely be brief and become extinct very quickly. The findings reported in the journal Astrobiology provide a possible explanation for what’s become known as the Fermi paradox – if the universe is full of alien life as often postulated why haven’t we found it yet? Third Sentinel satellite launched for Copernicus The European Space Agency has launched the third Sentinel Earth-observation satellite for Europe’s Copernicus environment programme. Sentinel-3A carries sensors to measure the temperature, colour and height of the sea surface as well as the thickness of sea ice. ASTRO-H launched JAXA the Japanese space agency has launched its new X-Ray astronomy satellite ASTRO-H aboard an H2A rocket from the Tanegashima Space Centre south of Tokyo. ASTRO-H is designed to study the hot and energetic universe using X-Ray eyes and extend into gamma ray wavelengths.

Series 19 Ep.4 Show Notes: Hunting the light from gravitational waves After last week’s historic detection of gravitational waves, astronomers have begun the hunt for a possible corresponding light source. The new research will help scientists place limits on the brightness that can serve as a benchmark for future observations linked to gravitational wave detections. Ancient Babylonian tablets used to track Jupiter A series of newly deciphered ancient Babylonian cuneiform tablets represent the earliest known examples of mathematical and geometric astronomy. The five clay tablets show how the ancient Babylonians tracked the movement of Jupiter using a form of calculus -- 14 centuries before its invention in Europe. Goodbye Philae The European Space Agency’s Rosetta mission has said farewell to its lost comet lander Philae. There’s been no communication with the tiny vehicle on the surface of Comet 67P since July. New Western Australian space tracking dish opens for business A new radio dish has been inaugurated at the European Space Agency’s New Norcia tracking station near Perth for communicating with spacecraft. The dish is under the flight path of rockets launched from ESA’s Kourou space port in French Guiana. #space #astronomy #science #SpaceTime #philae SpaceTime with Stuart Gary is bought to you in association with Australian Sky & Telescope magazine.

Stories in this episode: Gravitational waves detected for the first time Ripples in the fabric of spacetime known as gravitational waves have been directly seen for the first time. The historic announcement ends months of speculation and rumor. The Great Attractor Hundreds of galaxies hidden from view behind the Milky Way have been unveiled in unprecedented detail providing astronomers with new information about a mysterious object known as the Great Attractor. The findings shed new light on this massive gravitational anomaly, which appears to be drawing hundreds of thousands galaxies including the Milky Way towards it with a gravitational force equivalent to millions of billions of Suns. Earth's Ancient Crust Scientists have discovered 2.5 billion year old material from the ancient Earth in lava that's erupted from some oceanic volcanoes. The findings are the first evidence that Archean era planetary crust is being recycled through the mantle. Activity discovered on Saturnian moon Dione An 800 kilometre long mountain range on the Saturnian ice moon Dione is providing scientists with clues about how active the distant frozen world once was. The discovery also hints at possible continued activity even today. North Korea Satellite failure The satellite launched by North Korea last week appears to have failed to activate and is orbiting the Earth dead in space. The object which had been tumbling but had now stabilized but has failed to communicate with ground stations. #space #astronomy #science #news

Welcome to Ep.2 of Series 19...thank you for your continued support. In this episode: North Korea fires a shot across the world's bow North Korea has launched a rocket into space sparking global condemnation and growing fears over Pyongyang's ever expanding nuclear weapons program. Pyongyang claims the rocket was carrying a scientific satellite, but the rest of the world is concerned the rocket was testing ballistic missile technology for nuclear weapons delivery systems. Most powerful supernova explosion ever seen Astronomers have detected what they think is the most powerful stellar explosion ever seen -- a massive supernova -- twice as powerful as anything previously recorded. the huge blast was 200 times more powerful than the average supernova, 570 billion times brighter than our Sun, and 20 times brighter than all the stars in our Milky Way Galaxy combined. NASA warns of asteroid threat NASA is keeping a close eye on a 30 metre asteroid which is expected to come awfully close to Earth next month. The space rock named 2013-TX68 could pass just 17,700 kilometres above the planet's surface on March 5th, lower than the orbits of many satellites. China launches new navigation satellite China has launched a Long March 3C rocket carrying another member of Beijing's Beidou satellite navigation system. As well as providing navigation services for Beijing, the new satellite also features a particle detector to study the space environment around its orbit. Europe laser communications satellite launched A Russian Proton rocket has successfully blasted into orbit carrying a new telecommunications satellite equipped with a laser communications system. The new European Data Relay System will provide emergency services with near real time data relay services improving maritime surveillance and disaster response times.

The newly inferred planet – which is simply being called Planet Nine for now – has about ten times the mass of Earth and circles the Sun some 600 times further out than Earth’s orbit. NEW MOON GIANT IMPACT THEORY A new study claims the Earth’s Moon was formed out of a violent head on collision rather than a 45 degree angle side swipe between the early proto-Earth and a planetary embryo called Theia 4.6 billion years ago. The new study is based on a re-evaluation of oxygen isotopes in rock samples from both the Earth and the lunar surface. PLUTO THE WATER PLANET New data from NASA’s New Horizons spacecraft indicates the surface of Pluto has far more water than previously estimated. The new images have detected abundant signatures for water ice across the dwarf planet’s surface. FIRST ARIANE 5 LAUNCH FOR 2016 Arianespace has carried out its first launch of the year with an Ariane 5 blasting into orbit from the European Space Agency’s Kourou Space Port in French Guiana carrying the Intelsat 29e communications satellite into orbit.
