85: First confirmed interstellar visitor to our solar system SpaceTime with Stuart Gary

*First confirmed interstellar visitor to our solar system Astronomers have confirmed their first interstellar visitor to the solar system. The 400 metre wide newly discovered asteroid or comet has been designated A/2017 U1. *Asteroid Itokawa’s violent past Samples of the Asteroid Itokawa indicate the 500 metre wide space rock has had a violent history. The samples were collected by Japan’s Hayabusa spacecraft in 2005. *Rosetta’s comet provides missing link in planet formation Scientists have confirmed that planets are created by small particles of matter coming together over time to form progressively larger and larger bodies. The findings provide an important missing link in sciences understanding of how planets are formed. *Galaxies wobble at the centres of galaxy clusters Existing models on dark matter claim the super dense cores of the largest galaxy clusters contain massive galaxies with so much dark matter that that they never move. However new observations have shown that this density is much smaller than predicted, and that the galaxies at the centres of these clusters do move -- or at least wobble. *Yellowstone spawned twin super-eruptions that altered global climate Scientists have discovered that the last eruption of the Yellowstone super volcano was a double header event with two massive explosions spaced just 170 years apart. The findings are based on an analysis of volcanic ash which spewed from Yellowstone during the super eruptions 630 thousand years ago. *The Science Report New findings indicate European drought trends are lining up with climate change projections. Evidence that a huge carnivorous dinosaur roamed southern Africa 200 million year ago. Over 100 genetic risk factors linked to asthma, hay fever and eczema. Warnings that women who are underweight are more likely to experience early menopause. The small, flexible patch that analyses sweat straight from the skin to diagnose medical conditions. Scientific confirmation that fish have feelings. For enhanced Show Notes including photos to accompany this episode just visit: http://www.bitesz.com/spacetimeshownotes Subscribe, rate and review SpaceTime at all good podcasting apps…including iTunes, Google Podcasts, Stitcher, Pocketcasts, Podbean, Radio Public, Tunein Radio, google play, etcHelp support SpaceTime : The SpaceTime with Stuart Gary merchandise shop.
