Summary ‘Meteorites are the only natural source of material from beyond the Earth, providing invaluable evidence of how the Solar System formed and evolved. Over 66% of the total classified meteorites to date have been found in Antarctica. However, iron meteorites are under-sampled (0.7%) in the Antarctic collection compared with worldwide meteorite falls (5.5%). The team from the University of Manchester spent two austral summers in Antarctica exploring new blue icefield areas for meteorites using several methods. These included developing technology to identify sub-surface iron meteorites, to test the hypothesis that iron-rich meteorites are likely… Read More »LIVE talk | The Lost Meteorites of Antarctica | 18:30 (UK time), 9 November 2020.
How did Earth form? What was the composition of the starting material that made Earth, and how does its composition today differ from that starting material? How is Earth similar to or different from other planets in our Solar System, and how do we explain those similarities or differences? Earth, our home planet, is a great starting to point to answer questions like these. But Earth is an active planet, we have earthquakes, volcanoes, weather, etc., and the geological record from when it first formed 4.5 billion years ago has been overwritten. To properly answer these questions, and fully understand our Earth and its role in our Solar System, we… Read More »Introducing: The Isotope Geochemistry and Cosmochemistry Group at The University of Manchester
