Event Horizon Telescope reveals magnetic fields in central black hole
Boston MA (SPX) Dec 04, 2015
Most people think of black holes as giant vacuum cleaners sucking in everything that gets too close. But the supermassive black holes at the centers of galaxies are more like cosmic engines, converting energy from infalling matter into intense radiation that can outshine the combined light from all surrounding stars. If the black hole is spinning, it can generate strong jets that blast across thousands of light-years and shape entire galaxies. These black hole engines are thought to be powered by ... read more

What kinds of stars form rocky planets As astronomers continue to find more and more planets around stars beyond our own Sun, they are trying to discover patterns and features that indicate what types of planets are likely to form around ... more		Earth-sized telescope finds clue to black hole growth A new discovery, published in the journal Science, has greatly deepened our understanding black holes, which are believed to be the gravitational engines at the centres of most galaxies, including o ... more		Magnified image of faintest galaxy from early universe Astronomers harnessing the combined power of NASA's Hubble and Spitzer space telescopes have found the faintest object ever seen in the early universe. It existed about 400 million years after the b ... more
				Space mission to test gravitational wave detector lifts off The LISA Pathfinder mission was successfully this week and is now on its way to demonstrate technology for observing gravitational waves from space. Gravitational waves are ripples in the fabric of ... more		NASA team discover how water escapes from Saturn A University of Montana professor who studies astrophysics has discovered how water ions escape from Saturn's environment. His findings recently were published in the journal Nature Physics. UM Prof ... more

Fermi-type acceleration of interstellar ions driven by high-energy lepton plasma flows Stochastic acceleration and shock acceleration are well recognized as key mechanisms for cosmic ray generation since first proposed by Fermi. So far, these two mechanisms have been investigated wide ... more		Japan asteroid probe conducts 'Earth swing-by' in space quest A Japanese space probe launched last year passed by Earth on Thursday to harness the planet's gravitational pull to propel it toward a far away asteroid in its quest to study the origin of the solar system, authorities said. ... more		US lawmaker warns of military 'misunderstanding' risk with China Spain approves 'total' arms embargo against Israel Khamenei says Iran 'won't yield' to pressure to abandon uranium enrichment		LISA Pathfinder en route to gravitational wave demonstration ESA's LISA Pathfinder lifted off earlier today on a Vega rocket from Europe's spaceport in Kourou, French Guiana, on its way to demonstrate technology for observing gravitational waves from space. ... more
				CERN collides heavy nuclei at new record high energy The world's most powerful accelerator, the 27 km long Large Hadron Collider (LHC) operating at CERN in Geneva established collisions between lead nuclei, this morning, at the highest energies ever. ... more		What is the universe made of Matter known as ordinary, which makes up everything we know, corresponds to only 5% of the Universe. Approximately half of this percentage still eluded detection. Numerical simulations made it possi ... more

New law establishes ownership rights for space minerals A new public law signed by President Obama sets the stage for continued expansion of the U.S. space program and transforms the mining of space mineral resources (SMR). The President signed into law ... more		Half of Kepler's giant exoplanet candidates are false positives An international team led by Alexandre Santerne from Instituto de Astrofisica e Ciencias do Espaco (IA) made a 5-year radial velocity campaign of Kepler's giant exoplanet candidates, using the SOPHI ... more		Typhoon Ragasa hits south China after killing 15 in Taiwan Toxic homes a lasting legacy of Los Angeles fires Climate change causing havoc with global water cycle: UN		Researchers question results from the study of pulsating stars The movement of gas inside a star causes seismic waves which in turn cause irregularities on the star's surface. These 'earthquakes' (or pulsations) produce periodic variations in the brightness of ... more
LISA Pathfinder launch timeline On Thursday, a Vega rocket will boost LISA Pathfinder into space to pave the way to a future mission for detecting gravitational waves. Once aloft, ESA's mission control teams will pace the ultra hi ... more		'Fast radio burst' sheds new light on origin of these extreme events Fast Radio Bursts (FRBs), brief yet brilliant eruptions of cosmic radio waves, have baffled astronomers since they were first reported nearly a decade ago. Though they appear to come from the distan ... more		Cosmic filaments exposed near huge cluster ESA's XMM-Newton X-ray observatory has revealed three massive filaments of hot gas flowing towards a cluster of galaxies, uncovering a portion of the cosmic skeleton that pervades the entire Univers ... more		New insights into the creation of heavy elements Alpha particles, as the nuclei of the helium atom are also called, play a decisive role in the formation of heavier elements. Carbon, for instance, is formed from the fusion of these alpha particles ... more
