Australian-led astronomers find the most iron-poor star in the Galaxy, hinting at the nature of the first stars in the Universe.
A newly discovered ancient star containing a record-low amount of iron carries evidence of a class of even older stars, long hypothesised but assumed to have vanished.
In a paper published in the journal Monthly Notices of
the Royal Astronomical Society: Letters, researchers led by Dr Thomas
Nordlander of the ARC Centre of Excellence for All Sky Astrophysics in 3
Dimensions (ASTRO 3D) confirm the existence of an ultra-metal-poor red
giant star, located in the halo of the Milky Way, on the other side of the
Galaxy about 35,000 light-years from Earth.
German and Australian researchers are seeking opportunities in transition.
Moving away from fossil fuels is challenging, but it also
presents huge opportunities. At the Energy Transition Hub, more than 140
Australian and German researchers are working together to tackle the social and
technical challenges and take advantage of the trade and export opportunities.
Australian universities joined a European fleet of CubeSats to explore a
little-known layer of the atmosphere.
In May 2017, the European Union led a mission called QB50 to
launch a constellation of 50 mini-satellites from the International Space
Station. The pocket-sized CubeSats set out to study the thermosphere, the layer
of Earth’s atmosphere between 90 and 600 kilometres above the ground that
carries signals from GPS and other satellites.
Discovering our changing planet: a perfect France–Australia partnership
Professor Kurt Lambeck is one of Australia’s most eminent scientists—a geophysicist who revealed how the Earth changes shape and how these changes are tied to sea levels, the movement of continents, and the orbits of satellites. Vital to his career have been French collaborations that now span almost half a century.
Changing how communities think about water in Oceania
Water is a fundamental necessity of life, and managing water—who uses it and how—is a key challenge in developing countries.
Decisions about how to use scarce freshwater for drinking, agriculture, industry, and the environment can lead to conflict. In Oceania, this is often complicated by questions of who should make the decisions—governments, landholders, industry or others.
The brainpower of 18 institutions and more than $30 million are expanding the net to detect gravitational waves—disturbances in the fabric of spacetime—and cement Australia’s role in the emerging field.
Dating of ancient human teeth discovered in a Sumatran cave site suggests modern humans were in Southeast Asia 20,000 years earlier than previously thought.
The international research, led by Dr Kira Westaway from Macquarie University and published in Nature, has pushed back the timing of when humans first left Africa, their arrival in Southeast Asia, and the first time they lived in rainforests.
The work of Indonesian and Australian scientists is resulting in re evaluation of Jakarta’s seismic risk by Indonesian Government agencies.
The team is scanning the Earth from thousands of kilometres in the air, right down to chemical traces found in rocks, as they hunt out telltale signs of future earthquakes and the damage they might do. They’ve highlighted a major new seismic threat for East Java as well as the tsunami threat to Bali, Lombok, Nusa Tenggara, and other coasts along the Flores Sea; and have identified active faults in the Nusa Tenggara region of Eastern Indonesia, measuring the rates of strain building up.
A team from Universitas Gadjah Mada (UGM) and the Australian National University (ANU) are planning to use thousands of sensors to monitor heat, noise, human activity and power usage in commercial buildings in Yogyakarta. This data will help them design a real-time monitoring system that saves energy and can be used in commercial buildings across Indonesia.
Energy demand in Indonesia has grown by 150 per cent over the last 30 years. Electricity supply is struggling to keep up—blackouts are common in hospitals, hotels, offices, shopping centres and university laboratories.
