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

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

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 c

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

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 ha

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

Hi, Stuart here with the Show Notes for Series 19 Episode 65: *Quantum entanglement and the speed of light New research indicates that quantum entanglement -- the effect Albert Einstein referred to as spooky action at a distance -- isn’t just stranger than we imagine – it’s stranger than we can imagine. *A new way to determine the age of stars Scientists have developed a new way of understanding how stars like our Sun evolve. The new research is a first attempt to build a comprehensive model for the activity and evolution of these stars. *Discovery of an impossible cloud in the atmosphere of Titan Astronomers have detected a puzzling ice cloud that’s apparently formed out of thin air in the Saturnian moon Titan. The cloud -- detected in Titan's stratosphere -- is composed of a compound of carbon and nitrogen in the chemical cocktail that colours the giant moon's hazy, brownish-orange atmosphere. You can fi
