Despite its close-packed design, the Astronomia Solar Planets Jewelry displays the precious planets of our Solar System as Jacob-Cut®, 288-facet gemstone spheres, placed on the rotating platform of the Astronomia Solar caliber. Its three main arms carry the differential-driven, self-leveling time display, the magnesium globe in hand-painted blue for a spectacular representation of Planet Earth, the one-minute flying tourbillon regulating organ. Its subsidiary arms carry three Jacob-Cut®, 288-facet stones, along with a center-mounted, 1.5ct Citrine stone to represent our Sun. The Astronomia Solar Planets Jewelry makes for a beautifully artistic, highly refined and fully mechanical recreation of our solar system, to be appreciated like it has never been done before. At SIfA we use state-of-the-art techniques to study stars and their planetary systems. One of these techniques is high-resolution imaging which allows to study details on the finest possible scales.
Sydney Institute for Astronomy
Transients are astronomical objects that appear and disappear or change rapidly; they are our window to some of the most extreme processes in the Universe. Transient events can occur when black holes form, causing supernovae and gamma-ray bursts; when stars collide with black holes; or when hot, magnetised planets interact with their host stars. Through cutting-edge theoretical and observational research and the application of new technology for the next generation of instruments and telescopes. As well as being a research leader, SIfA is committed to excellence in postgraduate training and research-led undergraduate training. These are in-person gatherings where you can meet fellow enthusiasts and participate in activities right now.
- SIfA leads the GALAH spectroscopic survey to measure precise radial velocities and abundances of 30 elements for a million stars, and the Southern Stellar Stream Spectroscopic Survey (S5) that is mapping tidal streams within the Galactic Halo.
- Our astronomers and physicists are exploring this complex interface by examining the impact of particle physics on the evolution of the universe, pushing the boundaries of our theoretical understanding of how dark matter interacts with normal atoms.
- We know that it has been moulded by gravity, written within Einstein’s general theory of relativity, but the complex physics of gas, stars and magnetic fields means that making predictions from our theories is not straightforward.
- Shipping for all orders is a flat rate of $9.95 for Australian customers.
Australian astronomers are world leaders in the field of Galactic archaeology. The ages, chemistry and motions of stars across the Galaxy can be used to unravel how it first formed and evolved over billions of years. SIfA leads the GALAH spectroscopic survey to measure precise radial velocities and abundances of 30 elements for a million stars, and the Southern Stellar Stream Spectroscopic Survey (S5) that is mapping tidal streams within the Galactic Halo. A major SIfA strength is building dynamical models of the Galaxy through the use of both analytic functions, cosmological Real money casinos Australia and N-body simulations. The most critical events in the stellar life cycle are so remote that extremes of magnification are required to witness the key action. Another technique is asteroseismology, the study of oscillations in stars, which probes their interiors in exquisite detail.

Astroparticle physics is where the world of the microscopic, that of fundamental particles and fields, meets the large-scale universe. Our astronomers and physicists are exploring this complex interface by examining the impact of particle physics on the evolution of the universe, pushing the boundaries of our theoretical understanding of how dark matter interacts with normal atoms. At SIfA, astronomers undertake detailed computer simulations of the growth and evolution of comic structure, following the collapse of gas and dark matter from the smooth universe after the Big Bang to the wealth of galaxies we see around us today. These simulations present a huge data-challenge and supercomputer techniques are needed to unpick the details and reveal the structure.
Amateur Astronomy
We use data from NASA’s Kepler and TESS missions to measure tiny changes in stellar brightness, which allow to measure their internal properties, and also to infer the properties of their planets. There are also a multitude of mysterious transients of unknown origin, like fast radio bursts. Radio astronomy is undergoing a revolution in the discovery and study of transients. We lead projects on cutting-edge telescopes such as the Australian SKA Pathfinder (ASKAP) which allows us to see the dynamic radio sky in ways that were not previously possible.
Our new Astronomica design highlights the craftsmanship involved in the production of illuminated books. De sideribus tractatus is a 15th-century manuscript copy of De astronomia, a late 1st-century BC treatise on astronomy believed to have been composed by C. Julius Hyginus, a freedman of Augustus Caesar and chief librarian of the Palatine Library in Rome.
