The event -- which lasted over two hours -- was caused by a powerful blast from the Sun known as a Coronal Mass Ejection. *Over 15 thousand potentially deadly near Earth asteroids discovered Over 15 thousand potentially deadly near Earth asteroids have now been discovered by astronomers. Scientists are now detecting about 30 new asteroids in near Earth orbit’s – so called NEOs -- each week. *NASA opens new deep space communications dish near Canberra NASA has formally commissioned its latest dish at the Canberra Deep Space Communication Complex near Tidbinbilla. The new 34 metre antenna -- DSS36 – is part of a 120 million dollar upgrade by NASA to increase capacity at the Canberra facility by building two new dishes. *Japan launches new weather satellite Japan has launched its new Himawari 9 weather satellite aboard an H-IIA rocket from the Tanegashima Space Centre south of Tokyo. The new spacecraft together with its twin -- Himawari 8 launched two years ago – will provide the Japan Meteorological Agency and Australia’s Bureau of Meteorology with visible, infrared, and near-infrared images of cloud cover, sea surface temperatures, and particle movements from volcanic eruptions. *China launches its biggest rocket ever China has carried out the maiden flight of its biggest rocket ever – the new Long March 5. The 57 metre tall heavy lift launch vehicle blasted into orbit from Beijing’s new Wenchang spaceport located on an island in the South China Sea.

78: Proxima Centauri is more Sun like than previously thought

Stream episodes on demand from www.bitesz.com or www.spacetimewithstuartgary.com (both mobile friendly) *Proxima Centauri is more Sun like than previously thought A new study claims Proxima Centauri is more Sun like than previously thought. The new findings indicate our nearest stellar neighbour other than the Sun undergoes similar magnetic cycles to the Sun which however are far more dramatic. *New Horizons completes its epic data transfer from last year’s close encounter with Pluto NASA’s New Horizons mission has reached a major milestone with the last bits of science data from the July 2015 Pluto flyby finally transmitted to Earth. The valuable information had been stored on the spacecraft’s digital recorders since last year’s historic close encounter – mission managers being forced to drip feed the data back to Earth because of the huge distances involved. *New Pluto revelations continue to surprize scientists Meanwhile, data from earlier New Horizons Pluto downloads are continuing to provide surprising discoveries. Following the recent revelation that Pluto contains a large subsurface liquid water ocean -- and earlier discoveries of cryogenic ice volcanos and blue Plutonian skies -- scientists have now confirmed the dwarf planet has some of the brightest spots in the solar system reflecting an amazing 100 percent of the light they receive. *Very close asteroid flyby Astronomers have just witnessed a really close encounter with an asteroid which zoomed past the Earth between about 75 thousand and 96 thousand kilometres above the ground. The 22 metre wide space rock rocketed past the planet at over 21 kilometres per second just hours after first being spotted by the Mt. Lemmon Sky Survey in Arizona. *SpaceX hopes to be back before the end of the year SpaceX says it hopes to be back in the air before the end of the year. The company is continuing to work with NASA and the Federal Aviation Administration to determine the cause of September’s launch pad explosion at the Cape Canaveral Air Force Base which destroyed a Falcon 9 rocket and its satellite payload. *SKYWATCH Jonathan Nally the editor of Australian Sky and Telescope Magazine joins us to check out the night skies of November on Skywatch.

80: New gravity hypothesis could explain dark matter and dark energy

Stream episodes on demand from www.bitesz.com and www.spacetimewithstuartgary.com (both mobile friendly). *New gravity hypothesis could explain dark matter and dark energy A new hypothesis of gravity might explain dark matter and dark energy – the two biggest mysteries in science today. The new idea – called Emergent gravity -- appears to explain the exact same deviation in the motions of stars in galaxies that are usually explained by inserting dark matter in the theory. *Novae are the main source of Lithium in the universe A new study has discovered that most of the lithium in the universe is made in exploding stars called novae. The findings are based on observations of an unusually long and bright nova Sagittarii 2015 N.2 which occurred last year. *A new more detailed map of the galaxy Scientists have created one of the most detailed maps ever of our Milky Way Galaxy. The survey known as HI4PI -- examined neutral atomic hydrogen—the most abundant element in the universe and the main component of stars and galaxies. *November 15th’s super close supermoon The full Moon on Tuesday, November 15th, will be a little bigger and brighter than normal, because on that day the Moon will be closer to Earth than it’s been in nearly 69 years. At 22:23 Australian Eastern Daylight Time --11:23 Greenwich Mean Time -- the centres of the Moon and Earth will be just 356,509 kilometres apart.
