11: New study challenges popular theory about dwarf galaxies
09/02/2018 Duración: 27min*New study challenges popular theory about dwarf galaxies Existing hypothesis about how dwarf galaxies are spread across the universe is being challenged following the discovery of a plane of dwarf galaxies orbiting around Centaurus A. The findings challenge the long-held idea there are thousands of dwarf galaxies in all directions around large galaxies -- like bees swarming around a hive.*A new theory to explain the discovery of matter in hostile black hole winds Scientists have developed a new hypothesis to try to explain the origins of molecules discovered in the destructive cosmic outflows produced by supermassive black holes. If correct it could explain how stars form in extreme environments. *Arianespace places satellites into wrong orbits Arianespace has set up an independent investigation commission chaired by ESA’s General Inspector after its first launch for the year placed two telecommunications satellites into the wrong orbits.

10: New evidence that our galaxy is a cannibal
07/02/2018 Duración: 30min*New evidence that our galaxy is a cannibal Astronomers have discovered evidence confirming that the outer halo of the Milky Way contains stars stolen from neighbouring dwarf galaxies. The new findings support the idea of galactic cannibalism in which big galaxies grow bigger by merging or consuming smaller galaxies. *All systems go for Falcon heavy Space X is about to launch its largest and most powerful rocket ever -- the Falcon Heavy. The new 70 metre tall launch vehicle combines three Falcon 9 core stages mounted side by side. Instead of the usual dummy payload packed with scientific monitoring equipment – SpaceX boss Elon Musk is sending his own midnight cherry Tesla Roadster with David Bowie’s Space Oddity playing through the speakers. *Scientists discover how black holes regulate star formation in massive galaxies For year astronomers have noticed a direct relationship between the size of a galaxy and the mass of the supermassive black hole at its centre -- But the machinations of how it all worked h

Rocket Lab’s unmanned Electron launch vehicle – named Still Testing – blasted off from the Lift off Mahia Peninsula launch pad on Sunday afternoon. You tube video url: https://www.youtube.com/watch?v=sPcsZgmTRrg *Black hole burping Astronomers have caught a monster black hole in a distant galaxy snacking on gas and then "burping" — not once, but twice. The findings show two separate episodes of feeding frenzy by the supermassive black hole about 800 million light-years away. *The changing Sun Like the waistband of a couch potato in midlife, the orbits of planets in our solar system are expanding. It happens because the Sun’s gravitational grip gradually weakens as our star ages and loses mass. *Tiangong-1 crashing back to Earth Chinese space officials say their Tiangong 1 space station is still under control and will likely crash back to Earth in mid to late March. However, their inability to provide

6: Setting a size limit on neutron stars
24/01/2018 Duración: 31min*Setting a size limit on neutron stars A new study claims super dense stellar corpses known as neutron stars couldn’t get much bigger than twice the mass of the Sun. The findings solve a forty year old mystery that’s baffled scientists ever since neutron stars were first discovered. *New clues about the recipe for making stars Astronomers have shed fresh light on the importance of hydrogen atoms in the birth of new stars. Only hydrogen molecules are thought to directly fuel star formation. But new research shows there are more hydrogen atoms than molecules even in young galaxies that are making a lot of new stars. *Midwest Meteor The citizenry of the American mid-west have been treated to an unexpected celestial spectacular with the evening skies lit up by a bright meteor and sonic boom. People in the states of Ohio and Michigan and across the border in Ontario Canada witnessed the event around 8’0 clock local time. *No link between earthquakes and the full Moon A new study has provided more evidence to dispe

4: New clues about mysterious Fast Radio Bursts
17/01/2018 Duración: 33min*New clues about mysterious Fast Radio Bursts Astronomers have discovered new clues about mysterious cosmic blasts called Fast Radio Bursts – finding they originate from an environment bathed in extreme magnetic fields. While the new findings don’t shed any fresh light on what causes them – the research has provided some new insights to the deep space environment in which they occur. *Underground Martian water ice deposits exposed New images have revealed eight sites on Mars where thick subsurface deposits of water ice have been exposed on the cliff faces of eroding slopes. As well as holding clues about the red planet’s climate history – the findings also show how frozen water may be far more accessible for future missions to Mars than previously thought. *The universe has far more massive stars than expected Astronomers have discovered an excess of massive stars being formed in a giant stellar nursery in our neighbouring galaxy -- the Large Magellanic cloud. The findings are based on observations of 30 Dora

3: Black holes control star formation in galaxies
10/01/2018 Duración: 36min*Black holes control star formation in galaxies Astronomers have discovered a close correlation between the mass of a galaxy’s central black hole and how quickly that galaxy shunts down star formation. Young galaxies blaze with bright new stars forming at a rapid rate, but star formation eventually shuts down or quenches as galaxies evolves. *The Advanced Aviation Threat Identification Program via Space Nuts podcast The United States military has confirmed the existence of a modern-day version of Project Blue Book. Project blue book was a program run by the US Air Force during the 1960s to deal with reports of flying saucers and other Unidentified Flying Objects. *The Science Report Over a quarter of the world's landmass to become significantly drier because of global warming.

2: Solving the mystery of what came first.
05/01/2018 Duración: 26min*Solving the mystery of what came first? Astronomers may be a step closer to solving one of the greatest mysteries in astrophysics – which came first the galaxy – or the supermassive black hole at its centre. The problem is do galaxies form first from the accumulation of stars, globular clusters, and molecular gas and dust clouds -- with densities at the galactic centre eventually becoming so high it forms a black hole. *Supermassive black hole stellar factory Astronomers have discovered 11 newly formed infant protostars within three light years of the supermassive black hole at the centre of our galaxy. Black holes generate powerful gravitational tidal forces and intense ultraviolet and X-ray radiation – environments far more conducive to destroying stars rather than creating them. *Mars may not be as dry as it seems A new study suggests water on Mars is being absorbed by the red planet’s rocks like a sponge. The findings reported in the journal Nature suggest that Martian basalt rocks can hold up to 25 perc

03/01/2018 Duración: 31minHappy New Year!*Fireworks predicted from Rare Stellar Encounter in 2018 Astronomers are gearing up for high-energy fireworks in the next few months when a pulsar plows through the outer atmosphere of one of the galaxy’s brightest stars. The cosmic light show spectacular will occur just 5000 light years from Earth – astronomers aren’t sure exactly when – but it will be soon. *Bright Areas on Ceres Suggest Geologic Activity If you could fly aboard NASA's Dawn spacecraft, the surface of the dwarf planet Ceres would generally look quite dark, but with notable exceptions. These exceptions are the hundreds of bright areas that stand out in images Dawn has returned. *2018 promises to be another stellar year for astronomy There’ll be three partial Solar Eclipse in 2018. And as solar eclipses always occur about two weeks before or after a lunar eclipse there’ll be a couple of total lunar eclipses as well. *Cometary close encounter The next big cometary visitor scheduled to make a close encounter with Earth is the come

29/12/2017 Duración: 39min*NASA looking at missions to a comet and to Saturn’s moon Titan NASA has selected two finalist concepts for a robotic mission planned to launch in the mid-2020s. The agency is considering a comet sample return mission and a drone-like rotorcraft that would explore potential landing sites on Saturn’s largest moon, Titan. *Was the star of Bethlehem a real thing? For astronomy the idea of three wise men being guided by a star to a stable in a little town called Bethlehem two thousand years ago raises a number of problems. But let’s for a moment just suppose it really happened -- So, what star were they following? *ET’s not calling Scientists say they’ve detected no alien signals or any evidence of extraterrestrial technology coming from the strange cigar shaped interstellar visitor which speed through our solar system in September and October. The 400 metre long 40 metre wide asteroid designated A/2017 U1 and named Oumuamua the Hawaiian name meaning "messenger" or "scout"— has been the centre of astronomical att

93: The universe before the big bang
01/12/2017 Duración: 39min*The universe before the big bang A new hypothesis is proposing to eliminate the need for cosmological spacetime singularity and with it the big bang which kicked of the cosmos 13.8 billion years ago. Instead, physicists suggest the universe’s current expansion phase was preceded by a big crunch contraction and possibly a bouncing universe with infinite prior cycles of expansion and contraction. *The next nearest planet to our solar system A temperate Earth-sized planet has been discovered just 11 light-years away. The new world named Ross 128 b is currently the second-closest temperate planet ever detected – the nearest being Proxima b which orbits the star Proxima Centauri some 4.25 light years from Earth. *Dawn explores Ceres’ interior evolution Scientists have begun studying the internal structure and composition of the dwarf planet Ceres finding a close relationship between its internal evolution and its surface features. The findings used data collected by NASA’s Dawn spacecraft to analyse Ceres’ surfac
