UA researchers capture first photo of planet in making There are 450 light-years between Earth and LkCa15, a young star with a transition disk around it, a cosmic whirling dervish, a birthplace for planets. Despite the disk's considerable distance from ... more		Stormy space weather puts equatorial regions' power at risk Dr Brett Carter of the RMIT SPACE Research Centre and his team from RMIT, Boston College and Dartmouth College, found that these equatorial electrical disruptions threaten power grids in Southeast A ... more		Simple errors limit scientific scrutiny Researchers have found more than half of the public datasets provided with scientific papers are incomplete, which prevents reproducibility tests and follow-up studies. However, slight improvements ... more
				NIST team proves 'spooky action at a distance' is really real Einstein was wrong about at least one thing: There are, in fact, "spooky actions at a distance," as now proven by researchers at the National Institute of Standards and Technology (NIST). Eins ... more		Forged in the hearts of stars Apart from hydrogen, as many have heard from the Carl Sagan and Neil deGrasse Tyson "Cosmos" series, every ingredient in the human body is made from elements forged by stars. The calcium in our bone ... more

Two Moons About Saturn Although Dione (near) and Enceladus (far) are composed of nearly the same materials, Enceladus has a considerably higher reflectivity than Dione. As a result, it appears brighter against the dark ni ... more		'Chemical Laptop' Could Search for Signs of Life Outside Earth If you were looking for the signatures of life on another world, you would want to take something small and portable with you. That's the philosophy behind the "Chemical Laptop" being developed at N ... more		Greenland is helpful, but not vital, for US missile defense European military mission in Greenland as US aim 'remains intact' Amazon expands 'sovereign cloud' in Europe		Black holes don't need to spin to spit out jets Jet streams emanating or pulsing outward from stellar objects are often the result of rotational forces. Spinning has long been the explanation for the jets of black holes. ... more
				Astronomers discover a distant galaxy with a pulse Astronomers at Yale and Harvard have found a galaxy with a heartbeat - and they've taken its pulse. It is the first time scientists have measured the effect that pulsating, older red stars have on t ... more		Hubble Views a Lonely Galaxy Only three local stars appear in this image, quartered by right-angled diffraction spikes. Everything besides them is a galaxy; floating like a swarm of microbes in a drop of water, and brought into ... more

Queen's University Belfast lead research milestone in predicting solar flares An international team of researchers, led by Queen's University Belfast, has devised a high-precision method of examining magnetic fields in the Sun's atmosphere, representing a significant leap for ... more		Gaia consortium meets ahead of first data catalogue release next year From 16 to 20 November 2015, about two hundred members of the Gaia Data Processing and Analysis Consortium (DPAC) are meeting in Leiden, The Netherlands, to review the current status of preparations ... more		China bids to host secretariat of new high seas treaty Protected forests under threat in DRC's lucrative mining belt Hundreds in London protest against Beijing 'mega embassy'		3D visualisation redefines Milky Way's local architecture Astronomers have used modern techniques to visualise data from ESA's Hipparcos space astrometry mission in three dimensions. The treatment of the data has offered insights into the distribution of n ... more
Ultra-short X-ray pulses could shed new light on the fastest events in physics Ultra-short x-ray pulses could shed new light on the fastest events in physics. If you've ever been captivated by slow-motion footage on a wildlife documentary, or you've shuddered when similar tech ... more		Discovery of classic pi formula a 'cunning piece of magic' While most people associate the mathematical constant p (pi) with arcs and circles, mathematicians are accustomed to seeing it in a variety of fields. But two University of Rochester scientists were ... more		Experiment records extreme quantum weirdness An experiment in Singapore has pushed quantum weirdness close to its absolute limit. Researchers from the Centre for Quantum Technologies (CQT) at the National University of Singapore and the Univer ... more		Rocket Scientists to Launch Planet-Finding Telescope The university's rocket scientists - Prof. Supriya Chakrabarti and Asst. Prof. Timothy Cook of the Department of Physics and Applied Physics - are launching a rocket-borne experiment called PICTURE- ... more

	Discovery measures 'heartbeats' of distant galaxy's stars In many ways stars are like living beings. They're born; they live; they die. And they even have a heartbeat. Using a novel technique, astronomers have detected thousands of stellar "pulses" in the ... more		5400mph winds discovered hurtling around planet outside solar system Winds of over 2km per second have been discovered flowing around planet outside of the Earth's solar system, new research has found.
