b'*The best estimates yet of Earth\\u2019s composition Astronomers have determined the most accurate estimate yet of the Earth\\u2019s core, finding it makes up 32.5 per cent of the planet\\u2019s total mass. The findings are part of a new understanding of the Earth\\u2019s composition, which will help scientists develop new methods to determine if exoplanets orbiting distant stars are likely to be capable of supporting life.\\xa0*New supernovae study reframes the Dark Energy debate A new study claims the accelerating expansion of the universe may not be real, but could just be an apparent effect. The study claims the fit of Type Ia supernovae to a model universe with no dark energy appears to be very slightly better than the fit for the standard dark energy model.\\xa0*Curiosity climbing a Martian ridge NASA\'s Mars Curiosity rover has begun the steep ascent up an iron-oxide-bearing ridge that\'s grabbed scientists\' attention since before its arrival on the red planet in 2012. The Vera Rubin Ridge stands prominently on the north western flank of Mount Sharp, resisting erosion better than the less-steep portions of the mountain below and above it.\\xa0*Expedition 53 Launches to the International Space Station The Russian Soyuz MS-06 capsule carrying the Expedition 53 crew has successfully docked with the International Space Station as both spacecraft flew 400 kilometres above the southern Pacific Ocean off the coast of Chile. The docking with the station\\u2019s Space facing Russian Poisk module took place six hours after the Soyuz FG rocket launched from the Baikonur Cosmodrome in in the central Asian republic of Kazakhstan on a fast rendezvous flight path.\\xa0*Russian Proton launch It\\u2019s been a busy time for Russia with a Proton-M rocket successfully launching from the Baikonur Cosmodrome carrying the Amazonas-5 telecommunications satellite into geostationary transfer orbit. The mission was only the third for the Proton since its return to flight status following its latest grounding following a string of recent failures.\\xa0*The Science Report\\xa0New research has discovered that patients with age-related macular degeneration carry signs of the disease in their blood.\\xa0A new study has found the small fraction of papers denying climate change are all either biased or contain basic flaws in science.\\xa0Warnings that up to 85 percent of people living with HIV/AIDS suffer from chronic pain.\\xa0Generating power out or urine.\\xa0New research claims a mysterious ancient creature called Dickinsonia was definitely an animal.\\xa0Video for the Soyuz launch is at: https://www.youtube.com/watch?v=Eqsq3nKhe5M\\xa0And the video for the capsule docking is at: https://www.youtube.com/watch?v=vbFpagSZsGU\\xa0For Enhanced Show Notes, including photos to accompany this episode: http://www.bitesz.com/spacetime-show-notes\\xa0Subscribe, rate and review SpaceTime at all good podcasting apps\\u2026including iTunes, Google Podcasts, Stitcher, Pocketcasts, Podbean, Radio Public, Tunein Radio, google play, etc RSS feed: https://audioboom.com/channels/4642443.rss\\xa0 Learn more about your ad choices.
