How can we determine the age of a meteorite, or even the Solar System? How can we unravel the processes that formed Earth and the rest of the Solar System from the primordial dust cloud? The presence, or absence, of particular elements and isotopes in meteorites and their components, and the physics and chemistry of those elements, provides abundant clues to what happened in those first few million years.
Synopsis: "Over the next ten years a number of new giant telescopes will come on line - these include the European Extremely Large Telescope (E-ELT), the Square Kilometre Array (SKA) and in X-rays, Athena. Each one of these will dramatically change our view of the universe. At a recent workshop in Galway, "Speed and Sensitivity: Expanding Astronomical Horizons with ELTs" the possibilities from the current generation of instruments as well as the next generation of instruments for ELTs were discussed. This talk will look at what science is possible with ELTs and what questions will be addressed and hopefully answered by ELTs."
