Solving the mystery of the millions of missing stars Galactic cannibalism may be the clue to finally solving the mystery of the millions missing stars in the centres of some of the biggest galaxies. The study which examined the galactic cores of two of the largest known galaxies – has opened a new window into the processes that shape the evolution of massive galaxies. Uranus may have additional unseen moons The planet Uranus may have another two as yet undiscovered moons. A report claims unusual patterns just detected in two of Uranus’s dark rings could indicate the presence of two small moonlets between four and 14 kilometres wide. Meteoroids hitting the Moon at least a hundred times more frequently than previously thought A new study has found that small meteoroids are hitting the Moon at least a hundred times more frequently than previously thought. The findings raise fresh concerns about future long term human exploration of the lunar surface. Dramatic seasonal changes seen on Titan As Titan approaches its northern summer solstice, NASA's Cassini spacecraft has revealed dramatic seasonal changes in the atmospheric temperature and composition of Saturn's largest moon. The new observations show a polar reversal in Titan's atmosphere since Cassini arrived at Saturn in 2004. ​For a downloadable mp3 file version of this episode, please Click Here Subscribe, rate and review SpaceTime at iTunes, audioBoom, Google Play Store (US only...sorry), Pocketcasts, Podbean, Stitcher, Tunein Radio, Radioline or any good podcatcher app. Email: SpaceTime@bitesz.com Join our mailing list at http://www.bitesz.com/join-our-mailing-list ​ For more, follow SpaceTime on Facebook, twitter, Tumblr, YouTube, Google+ and Clammr: Facebook: @spacetimewithstuartgary twitter: @stuartgary Tumblr: http://spacetimewithstuartgary.tumblr.com/ Google+: https://plus.google.com/u/2/collection/cabtNB YouTube: Click Here Clammr: Click Here If you're enjoying SpaceTime, please help out by sharing and telling your friends.

New Questions about dark energy and the ultimate fate of the universe A new study of exploding stars has raised fresh questions about the existence of Dark Energy – a mysterious force causing the expansion of the universe to accelerate at a faster and faster rate. The findings could have important implications for the ultimate fate of the universe. The most volcanically active world in the solar system A new study of Jupiter’s moon Io has raised fresh questions about the most volcanically active world in the solar system. The findings identified some eruptions which seem to progress across the 3600-kilometre wide moon’s surface progressively triggering one eruption after another often five hundred kilometres apart. Investigators trying to determine why the Mars lander crashed and burned Officials with the European Space Agency are continuing to sift through data to try and determine what caused last week’s crash of the ExoMars Schiaparelli lander on the red planet’s surface. Images from NASA's Mars Reconnaissance Orbiter identified new markings on the Martian landscape believed to be related probe’s crash on October 19. New Australian defence satellites ready for space A state-of-the-art miniature satellite that will play an important role in developing Australian Defence space capability is ready for launch after successfully passing a set of gruelling tests that simulate the harsh environment of space. The new Buccaneer satellite is the first of two being tested in a joint program to build Australian capability to develop and fly satellite missions.

Europe’s Schiaparelli Mars lander lost on its final decent to the red planet’s surface.
Mission managers at the European space Agency are still struggling to re-establish contact with its Schiaparelli Mars lander. The 577 kilogram spacecraft lost contact with ESA mission control in Darmstadt Germany during its six minute journey to the surface of the red planet. Juno spacecraft suddenly enters emergency safe mode NASA’s Juno spacecraft which is exploring Jupiter suddenly entered safe mode on Tuesday. Early indications are a software performance monitor induced a reboot of the spacecraft’s on board computer. The operation prevented the probe’s science instruments from working during the Jovian flyby. More evidence for a ninth planet on the edge of our solar system The yet to be discovered Planet Nine -- which may lurk beyond Neptune on the dark outer rim of our solar system – could explain the mysterious six degree difference between the Sun’s equator and the ecliptic or average orbital plane of the planets. The new findings provide astronomers with their first compelling evidence to explain the unusual wobble of the planets with respect to the Sun’s equator. Expedition 49 Launch to the International Space Station A Russian Soyuz rocket has successfully launched into space from the Baikonur Cosmodrome in the central Asian republic of Kazakhstan carrying three new expedition 49 crew members to the International Space Station. It will be a busy time for the new crew with more than 250 experiments scheduled -- covering biology, Earth sciences, human research, physical sciences and technology development.

The findings are based a new study of data from the Earth orbiting Hubble Space Telescope and other ground and space based observatories. How Pluto paints its largest moon red Pluto’s binary partner and largest moon Charon owes its unusual reddish polar colouring to methane gas escaping Pluto’s atmosphere and becoming trapped by Charon’s gravity -- eventually freezing on to its cold, icy surface. The findings resolve a long standing mystery which began in June 2015, when the cameras on NASA’s approaching New Horizons spacecraft first spotted the strange reddish polar region on Charon. Square Kilometre Array software tested on one of the world’s fastest super computers Prototype software designed to manage data from the Square Kilometre Array telescope is being tested on the world’s second fastest supercomputer in China. Once installed on the SKA the complete system will process raw observations of distant stars and galaxies and turn them into data that can be analysed by astronomers around the world. China launches two taikonauts on a month long space mission China has successfully launched two taikonauts on a month long mission into orbit. The Shenzhou 11 spacecraft blasted off from the Jiuquan Satellite Launch Centre in the Gobi Desert to rendezvous and dock with the Tiangong 2 orbiting laboratory launched last month.

New cosmic map solves one mystery but deepens another The most precise ever map of the large scale structure of the universe has confirmed predictions of Albert Einstein’s general theory of relativity. However, the findings have also deepened a long-standing cosmological mystery about an unexplained so-called cold spot covering a vast sector of the universe. New world discovered in the outer reaches of the solar system A new world has been discovered in the outer reaches of the solar system some 13.6 billion kilometres from the Sun. The distant frozen world was originally detected in 2014 and has now been confirmed by the International Astronomical Union. Strange double peanut shaped galaxies discovered Astronomers have discovered weird structures shaped like double peanuts in two nearby galaxies. The discovery reported in the Monthly Notices of the Royal Astronomical Society are thought to provide new clues about the history of these galaxies. Schiaparelli prepares to land on Mars In less than a week from now the European Space Agency’s ExoMars entry, descent and landing module Schiaparelli will touch down on the frozen arid surface of the red planet. The cone-shaped lander was launched on 14 March attached to ESA’s ExoMars Trace Gas Orbiter spacecraft for the seven-month journey to Mars.

Confirmation that Tunguska was caused by asteroid airburst
Scientists have finally confirmed that an asteroid caused the Tunguska impact event in 1908. The findings reported in the journal Planetary and Space Science are based on tiny mineral samples of debris from the Tunguska impact zone that are absolutely characteristic of a meteorite. Giant cannonballs seen shooting from star Astronomers have detected mysterious superhot balls of plasma -- each almost the size of Earth -- being ejected near a dying star. The plasma blobs are moving through space at some 770 thousand kilometres an hour -- so quickly they could fly from the Earth to the Moon in just half an hour. Australian NBN satellite launched Sky Muster 2 the second of two new NBN telecommunications satellites has been successfully launched into orbit aboard an Ariane 5 ECA heavy lift rocket. Arianespace mission number VA231 blasted off into late afternoon skies from launch complex ELA-3 at the European Space Agency’s Kourou space port in French Guiana. New Shepherd flight test success Blue Origin have successfully tested the launch abort escape system for the company’s New Shepard rocket. The test was the fifth flight for the New Shepard vertical take-off and vertical landing spacecraft which is designed to take passengers and scientific payloads on sub orbital ballistic flights to altitudes of over 100 kilometres or 328 thousand and 84 feet -- the official start of space.

A new test for cosmological inflation
When the universe burst into existence in the big bang 13.8 billion years ago – something must have happened during the first nanoseconds that caused it to suddenly expand from a singularity of infinite density and virtually zero dimensions in to the universe we see today. Scientists call this mysterious event cosmological inflation -- the problem is they have no real idea what it actually is – and what physical mechanisms drove it. More mystery surrounding an already strange star Last month we reported how astronomers think they may finally have solved the mystery surrounding a weird erratically flickering and dimming star -- whose strange behaviour -- sparked speculation that it could have been our first sign of an advanced alien civilization. However, a new study has reopened the mystery. Saturn’s moon Dione has a subsurface ocean New data from NASA’s Cassini spacecraft has confirmed the existence of another subsurface ocean on a moon in the outer solar system. Cassini has discovered the ocean under the surface of the Saturnian moon Dione. Nobel Prize in physics goes to topology in materials This year’s Nobel prize for physics has gone to David Thouless, Duncan Haldane and Michael Kosterlitz for revealing the secrets of exotic matter. The trio used advanced mathematical methods to study unusual phases, or states, of matter, such as superconductors, superfluids and thin magnetic films.

The incredible shrinking planet Mercury
The planet Mercury is shrinking according to a new analysis of data gathered by a NASA spacecraft. The findings are based on a series of small previously undetected cliff-like tectonic structures on the planet’s surface known as thrust fault scarps. Rosetta’s grand finale After a journey lasting over 12 and a half years Rosetta’s mission is finally over. Rosetta discovered over 60 molecules, 34 of which had never been found before on a comet. These include oxygen and the amino acid glycine, a basic building block of life. It also confirmed that Earth’s water probably didn’t come from comets – but rather asteroids. Solar Minimum on its way Over the last few days AR2597 -- the last remaining sunspot group on the surface of our local star the Sun – disappeared. The blank solar face – the fourth this year -- is a sign that the Sun’s 11 year solar cycle is now heading towards Solar Minimum. Skywatch October Well you’ve probably heard of a blue moon – the rare occurrence of a second full Moon in the one calendar month – but have you ever heard of a black moon. New super heavy lift launch vehicle Blue Origin have announced details of a new super heavy lift launch vehicle. Blue Origin have leased Space Launch Complex 36 at the Cape Canaveral Air Force Base in Florida for their new rocket which could be flying by 2020.
