48: Rare Meteorites Challenge Our Understanding of the Solar System

Stream Episodes on demand from www.bitesz.com or www.spacetimewithstuartgary.com (both mobile friendly) * Rare meteorites challenge our understanding of the solar system Astronomers may need to revise sciences current understanding of the early solar system following the discovery of rare minerals in ancient meteorites. The new findings mean the history and evolution of the solar system may have been somewhat different from what scientists previously thought. *The volcano that almost wiped out the human species still alive and active A new study has concluded that the Toba super volcano which almost wiped out the human species 74 thousand years ago – is still alive and active today. The report has warned that the rare but spectacular eruptions of super volcanoes experience ongoing, smaller eruptions for tens of thousands of years after the initial event. *New evidence of frost on Moon's surface Scientists using data from NASA's Lunar Reconnaissance Orbiter have identified bright areas in craters near the Moon's south pole cold enough to have lunar surface frost. The new findings are based on an analysis that combined surface temperatures with information about how much light is reflected off the moon's surface. *No Universe without the big bang Professor Albert Einstein’s relativity theory tells us that the curvature of spacetime was infinite at the time of the big bang 13.8 billion years ago. The problem is sciences mathematical understanding breaks down at that point of singularity. Now scientists have tried to take that a step further. *Ariane 5 launches its heaviest payload ever An Ariane 5 rocket has carried its heaviest yet payload launch into orbit. Arianespace flight VA237 blasted off from the European Space Agency’s Kourou space port in French Guiana carrying the ViaSat-2 and Eutelsat-172B telecommunications satellites into geostationary transfer orbits. The Ariane rocket launch video is at https://www.youtube.com/watch?v=zy_lrhoyxtc  Learn more about your ad choices.
