The GAIA satellite was launched yesterday. Placed on one of Earth’s outermost orbits, it will survey more than one billion stars in our galactic neighborhood and help us know more about the Universe. Federico Belloni and Christophe Paccolat, scientific assistants at the Swiss Space Center, explain why this mission is exceptional.
Astronomers led by a Curtin University researcher have discovered a new population of exploding stars that "switch off" their radio transmissions before collapsing into a Black Hole.
Smooth" or grainy? Is space-time continuous or is it made up of very fine (10-35 metres on the "Planck scale") but discrete grains, if we look at it very close up ? If the latter were true, scientists think, this would lead to deviations from the theory of special relativity formulated by Albert Einstein more than 100 years ago.
Even the so-called high-Tc superconductors still require very low temperatures of minus 200 degrees centigrade. While cooling down to these temperatures involves substantial effort, superconductors are already employed in many areas, e.g., for magnetic resonance tomography in medical applications. Despite extensive research, materials providing lossless conduction of electricity at room temperature are missing up to now.
Massive stars – those at least 8 times the mass of our Sun – present an intriguing mystery: how do they grow so large when the vast majority of stars in the Milky Way are considerably smaller?
New research using data from NASA's Van Allen Probes mission helps resolve decades of scientific uncertainty over the origin of ultra-relativistic electrons in Earth's near space environment, and is likely to influence our understanding of planetary magnetospheres throughout the universe.
Though it was hailed as a triumph for the "Standard Model" of physics – the reigning model of fundamental forces and particles – physicists were quick to emphasize that last year's discovery of the Higgs boson still left gaps in our understanding of the universe.
To date, scientists have confirmed the existence of more than 900 exoplanets circulating outside our solar system.
A small band of particle-seeking scientists at Yale and Harvard has established a new benchmark for the electron's almost perfect roundness, raising doubts about certain theories that predict what lies beyond physics...
A monthly look at the night skies of the northern Rocky Mountains, written by astronomers Ron Canterna, University of Wyoming; Jay Norris, Challis, Idaho Observatory; and Daryl Macomb, Boise State University.
GridCOM Technologies, the leader in quantum cyber security solutions, has been cited by editors at Popular Science magazine as "the best evidence" that unhackable quantum encryption technology is one of the 20 ideas that will change the world. The article appears in the January 2014 issue on newsstands now.
Nature performs remarkable feats of chemistry — enabling, for example, plants to take in sunlight, water and carbon dioxide to create their own food, and in the process, pump out oxygen for the rest of the planet.
NASA's Near-Earth Object Wide-field Infrared Survey Explorer (NEOWISE), a spacecraft that made the most comprehensive survey to date of asteroids and comets, has returned its first set of test images in preparation for a renewed mission.
The coexistence of two opposing phenomena might be the secret to understanding the enduring mystery in physics of how materials heralded as the future of powering our homes and communities actually work, according to Princeton University-led research. Such insight could help spur the further development of high-efficiency electric-power delivery.
UBC researchers have discovered a prevalent electronic state that controls the behaviour of high-temperature superconducting copper-oxide ceramics.
