Australia Expands Its Capability in Adaptive Optics and Quantum Communication

7 hours 56 min ago
International Astronautical Federation: The Australian National University (ANU) has welcomed funding from both the Federal Government and the ACT Government to expand its capability in adaptive optics and quantum communication. The Australian Research Council has supported the development of a new laser system for the first Australian laser guide star to be developed at the Advanced Instrumentation and Technology Centre (AITC) The laser guide star system will be crucial for civil and defence telescopes such as the new Giant Magellan Telescope under construction in Chile, as well as systems to track space debris. “The ground-based telescopes used to study the universe, image satellites or track space debris all require laser guide star adaptive optics to defeat the blurring caused by atmospheric turbulence,” Assoc Prof d’Orgeville said. “The semiconductor guide star laser is a key component of these systems, and the AITC will now be in a position to provide a complete solution to the problem.” The Space Based Quantum Communications project also leverages the AITC’s adaptive optics expertise. The project brings together the space, telescope, adaptive optics, quantum information and optical communications capabilities of the ANU Department of Quantum Science, the AITC, UNSW Canberra, and ANU spin out companies, QuintessenceLabs and Liquid Instruments. ...

Diamond’s 2-billion-year growth charts tectonic shift in early Earth’s carbon cycle

Europlanet Research Infrastructure: Diamond’s 2-billion-year growth charts tectonic shift in early Earth’s carbon cycle A study of tiny mineral ‘inclusions’ within diamonds from Botswana has shown that diamond crystals can take billions of years to grow. One diamond was found to contain silicate material that formed 2.3 billion years ago in its interior and a 250 million-year-old garnet crystal towards its outer rim, the largest age range ever detected in a single specimen. Analysis of the inclusions also suggests that the way that carbon is exchanged and deposited between the atmosphere, biosphere, oceans and geosphere may have changed significantly over the past 2.5 billion years.

Gress, VU Amsterdam ‘Although a jeweller would consider diamonds with lots of inclusions to be flawed, for a geologist these are the most valuable and exciting specimens,’ said Prof Gareth Davies, of Vrije Universiteit (VU) Amsterdam, who co-authored the study. ‘We can use the inclusions to date different parts of an individual diamond, and that allows us to potentially look at how the processes that formed diamonds may have changed over time and how this may be related to the changing carbon cycle on Earth.’ Sixteen diamonds ...
