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.
SpaceTime with Stuart Gary 11 Oct 2017, 04:35 UTC Stream episodes on demand from www.bitesz.com (mobile friendly) *A possible cradle of life discovered on Mars Evidence of massive ancient sea floor hydrothermal vent deposits have been discovered on Mars. 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.
Naked Astronomy 9 Oct 2017, 23:00 UTC Two astronauts and an Imperial Storm Trooper join the Space Boffins podcast from The Netherlands at the European Space Agency's ESTEC Open Day - where thousands of people can see the Agency's spacecraft testing facilities and meet the scientists and engineers involved in ESA space missions. Sue Nelson and Richard Hollingham catch up with ESTEC head Franco Ongaro; Europe's first woman on the International Space Station, Claudie Haigner; a Star Wars Storm Trooper otherwise known as Rosetta project scientist Matt Taylor; as well as the British-born NASA born astronaut Michael Foale and his plans to save the International Space Station.
StarDate Online 9 Oct 2017, 05:00 UTC High-school student Michelle Knapp was watching TV at her parents’ house in Peekskill, New York, when she heard what sounded like a three-car pile-up outside. When she checked, though, she saw only one damaged car: her own. The 1980 Chevrolet Malibu had a crumpled bumper and trunk. And beneath it was a warm rock the size of a bowling ball, partially embedded in the gravel driveway: a 26-pound space rock that had fallen to Earth.
