SpaceTime with Stuart Gary 13 Oct 2017, 06:50 UTC Stream episodes on demand from www.bitesz.com (mobile friendly) *A radio for dark matter Scientists are developing a new device that instead of searching for dark matter particles – will search for dark matter waves. A prototype of the new device is now being tested to listen for the sounds of mysterious dark matter particles. *Ring found around dwarf planet Haumea Astronomers have detected another ringed world in our solar system. As well as the gas giants; Jupiter, Saturn, Uranus, and Neptune, the Kuiper Belt dwarf planet Haumea has now also been found to have a ring system. *JUNO’s eighth Jovian flyby NASA’s Juno spacecraft has completed its eighth close encounter with Jupiter -- flying just 7576 kilometres above the giant planet’s swirling cloud tops. The new observations show close-up images of two points of interest, known as ‘Whale’s Tail’ and ‘Dan’s Spot.’ *Asteroid 2012 TC4 zooms past Earth An asteroid the size of a house passed just 50,150 kilometres above the South Pacific Ocean on Thursday travelling at over 7.6 km per second relative to Earth. Known as a NEO or Near Earth Object – the asteroid designated 2012 TC4 -- hadn’t been seen since the week it was discovered ...

ESOcast 12 Oct 2017, 10:00 UTC What are you made of? You’re made of matter, which is made of molecules, which are made of atoms. But where did those atoms come from? The ones in you! How were they formed? Well, they were created inside of stars! Really, you’re made of star stuff!
Hubblecast HD 11 Oct 2017, 14:00 UTC The atmosphere of an exoplanet can reveal a wealth of information, such as the planet’s temperature, its air pressure, and whether it is suitable for life. However, studying exoplanet atmospheres is one of the most challenging tasks in modern astronomy — and a challenge for Hubble too. This new episode of the Hubblecast describes how exoplanet atmospheres are analysed and what makes it such a challenge.

Hydrothermal vents found on the mid ocean ridges of Earth, pump a rich chemical soup into the surrounding oceans, which many scientists believe could be where life on Earth began. *Chemical signatures for life discovered near and far Freon-40, a chemical signature of life has been detected -- both around a distant star -- and much closer to home – in a comet orbiting the Sun. The discovery includes the first ever detection of a saturated organohalogen chemical compound in interstellar space. *Cosmic rays from distant galaxies A fifty year long debate has finally been resolved with confirmation that the highest energy cosmic rays originate from sources far beyond our galaxy. The findings are based on the uneven distribution of high energy cosmic rays bombarding the Earth from different positions across the sky. *Mysterious Dimming of Tabby's Star May Be Caused by Dust Astronomers say a large cloud of dust remains the most likely cause for the mysterious changes in brightness effecting Tabby’s Star. The star became famous 2015, when ...
StarDate Online 10 Oct 2017, 05:00 UTC Several well-known meteor showers punctuate this month’s night skies. Most of them produce only a handful of “shooting stars” per hour, so there’s not much to see. And even the best of them generate no more than a score of meteors per hour, and only for a short time. Astronomers have also compiled a list of possible meteor showers — more than 300 spread throughout the year. And they’re using networks of automated cameras and telescopes to try to confirm them. The observations will help the astronomers identify the objects that cause the showers.
