NSF-Funded Physics Frontiers Center Expands Hunt for Gravitational Waves
Pasadena CA (SPX) Mar 31, 2015
The search for gravitational waves-elusive ripples in the fabric of space-time predicted to arise from extremely energetic and large-scale cosmic events such as the collisions of neutron stars and black holes-has expanded, thanks to a $14.5-million, five-year award from the National Science Foundation for the creation and operation of a multi-institution Physics Frontiers Center (PFC) called the North American Nanohertz Observatory for Gravitational Waves (NANOGrav). The NANOGrav PFC will be direc ... read more

Saturn Spacecraft Returns to the Realm of Icy Moons A dual view of Saturn's icy moon Rhea marks the return of NASA's Cassini spacecraft to the realm of the planet's icy satellites. This follows nearly two years during which the spacecraft's orbits ca ... more		Earthlike 'Star Wars' Tatooines may be common Luke Skywalker's home in "Star Wars" is the desert planet Tatooine, with twin sunsets because it orbits two stars. So far, only uninhabitable gas-giant planets have been identified circling such bin ... more		MESSENGER Completes 4,000th Orbit of Mercury On March 25, the MESSENGER spacecraft completed its 4,000th orbit of Mercury, and the lowest point in its orbit continues to move closer to the planet than ever before. The orbital phase of the MESS ... more
				Astronomers Upgrade Their Cosmic Light Bulbs The brilliant explosions of dead stars have been used for years to illuminate the far-flung reaches of our cosmos. The explosions, called Type Ia supernovae, allow astronomers to measure the distanc ... more		Black hole winds pull the plug on star formation Astronomers using ESA's Herschel space observatory have found that the winds blowing from a huge black hole are sweeping away its host galaxy's reservoir of raw star-building material. Found at the ... more

NASA's Hubble, Chandra Find Clues that May Help Identify Dark Matter Using observations from NASA's Hubble Space Telescope and Chandra X-ray Observatory, astronomers have found that dark matter does not slow down when colliding with itself, meaning it interacts with ... more		Science: Theory of the strong interaction verified The fact that the neutron is slightly more massive than the proton is the reason why atomic nuclei have exactly those properties that make our world and ultimately our existence possible. Eighty yea ... more		EU states to hold talks on 'drone wall' to protect bloc Denmark military intel fails to identify source of drone flights Lithuania eases rules on shooting down drones		Best view yet of dusty cloud passing galactic center black hole A supermassive black hole with a mass four million times that of the Sun lies at the heart of the Milky Way galaxy. It is orbited by a small group of bright stars and, in addition, an enigmatic dust ... more
				Dark matter not as sticky as once thought Astronomers using observations from NASA's Hubble Space Telescope and Chandra X-ray Observatory have found that dark matter does not slow down when colliding with each other. This means that it inte ... more		Automation offers big solution to big data in astronomy It's almost a rite of passage in physics and astronomy. Scientists spend years scrounging up money to build a fantastic new instrument. Then, when the long-awaited device finally approaches completi ... more

Help Name New Features on Pluto In partnership with NASA's New Horizons mission and the SETI Institute, the IAU is endorsing a campaign that will allow the public to participate in naming newly discovered features on Pluto and its ... more		Supermassive black hole clears star-making gas from galaxy's core Many nearby galaxies blast huge, wide-angled outpourings of material from their center, ejecting enough gas and dust to build more than a thousand stars the size of our sun every year. Astronomers h ... more		NASA ISRO radar satellite beams first Earth images from space Morocco High Atlas whistle language strives for survival China warns Papua New Guinea over Australian defence deal		NASA-Funded Mission Studies the Sun in Soft X-Rays At any given moment, our sun emits a range of light waves far more expansive than what our eyes alone can see: from visible light to extreme ultraviolet to soft and hard X-rays. Different wavelength ... more
Behind the dogmas of good old hydrodynamics A new theory, which gives new insights into the transport of liquid flowing along the surface under applied electric field, was developed by the group of Russian scientists lead by Olga Vinogradova ... more		Engineers speed up simulations in computational grand challenge Engineers at the University of California, San Diego, have developed a new family of methods to significantly increase the speed of time-resolved numerical simulations in computational grand challen ... more		Super sensitive measurement of magnetic fields There are electrical signals in the nervous system, the brain and throughout the human body and there are tiny magnetic fields associated with these signals that could be important for medical scien ... more		An explanation for the Fermi-Pasta-Ulam system problem A team of researchers, led by Rensselaer Polytechnic Institute professor Yuri Lvov, has found an elegant explanation for the long-standing Fermi-Pasta-Ulam (FPU) problem, first proposed in 1953, inv ... more
