News About Physics 22-JUL-08 en-us Washington DC (SPX) Jul 07, 2008 - Taking advantage of a unique cosmic configuration, astronomers have measured an effect predicted by Albert Einstein's theory of General Relativity in the extremely strong gravity of a pair of superdense neutron stars. Essentially, the famed physicist's 93-year-old theory passed yet another test.]]> ]]> Pasadena CA (SPX) Apr 03, 2008 - The Advanced LIGO Project, an upgrade in sensitivity for LIGO (Laser Interferometer Gravitational-wave Observatories), was approved by the National Science Board in its meeting on March 27. The National Science Foundation will fund the $205.12 million, seven-year project, starting with $32.75 million in 2008.]]> Paris, France (ESA) Mar 05, 2008 - ESA astronaut Leopold Eyharts has activated the first experiment inside the European Columbus laboratory. The WAICO experiment, which investigates the effect of gravity on plant root growth, has started inside the module's Biolab facility.]]> Blacksburg, Va. (UPI) Feb 18, 2008 - A U.S. graduate student has won second place in a "Greener Gadgets Conference" competition for his invention of a floor lamp that's powered by gravity.]]> ]]> Milwaukee WI (SPX) Nov 18, 2007 - Using new tools to look at the universe, says Patrick Brady, often has led to discoveries that change the course of science. History is full of examples. "Galileo was the first person to use the telescope to view the cosmos," says Brady, a UWM professor of physics. "His observations with the new technology led to the discovery of moons orbiting Jupiter and lent support to the heliocentric model of the solar system."]]> Daytona Beach FL (SPX) Nov 05, 2007 - Researchers, teachers and students will have access to weightless and variable-gravity conditions under a new agreement between Embry-Riddle Aeronautical University and Zero Gravity Corp. (Zero-G). Embry-Riddle and Zero-G will work together to integrate weightless flights and space science workshops for K-12 teachers, develop experiment programs for high school and college students, and expand microgravity, lunar gravity, and Mars gravity research opportunities aboard Zero-G's G-Force One aircraft.]]> Paris, France (ESA) Sep 12, 2007 - Colourful aurorae and perturbations of GPS signals are just some of the effects of a magnetospheric phenomenon known as a magnetic substorm. Up to now, the onset of this phenomenon has been explained by two competing models: current disruption and near-Earth reconnection. A new study published 20 January 2007 in Geophysical Research Letters challenges this binary vision of substorm onset. Thanks to simultaneous measurements performed by the four satellites of the ESA/NASA Cluster mission and the CNSA/ESA Double star mission, a third type of substorm onset is now suggested.]]> ]]> Paris, France (SPX) Jul 20, 2007 - GOCE, ESA's first satellite dedicated to measuring the Earth's gravity field, has been presented to the press today in Turin, Italy, before being shipped to ESTEC - the space agency's research and technology centre in the Netherlands - for final testing. The Gravity field and steady-state Ocean Circulation Explorer(GOCE), the first core Earth Explorer mission to be developed as part of ESA's Living Planet Programme, will significantly advance our knowledge of how the Earth works and provide insight into ocean circulation, sea-level change, climate change, volcanism and earthquakes.]]> Kingston, Canada (SPX) Jun 07, 2007 - A team of astronomers has found that a certain class of double white dwarf stars, millions of which populate the Milky Way Galaxy, are expected to be a prominent source of gravitational waves for the Laser Interferometer Space Antenna (LISA). These results are different from previous studies of a similar nature, which showed that active (interacting) white dwarf binary stars will not be a very significant source of gravitational waves, compared to their detached (non-interacting) counterparts.]]> Columbia, MO (SPX) Jun 05, 2007 - Albert Einstein's theory of general relativity has fascinated physicists and generated debate about the origin of the universe and the structure of objects like black holes and complex stars called quasars. A major focus has been on confirming the existence of the gravitomagnetic field, as well as gravitational waves.]]> ]]> ]]> Huntsville AL (SPX) Jun 06, 2007 - A new way of looking at a previously abandoned mathematical model might help astronomers study and accurately identify an exotic clan of gravitational waves. The waves in question come from small black holes or neutron stars in extremely elongated orbits around vastly larger black holes, says Dr. Lior Burko, an assistant physics professor at The University of Alabama in Huntsville (UAH). "This reopens an area of research that was closed several years ago."]]> Jacksonville FL (SPX) Apr 17, 2007 - For the past three years a satellite has circled the Earth, collecting data to determine whether two predictions of Albert Einstein's general theory of relativity are correct.]]> Pasadena CA (SPX) Mar 06, 2007 - The Laser Interferometer Gravitational-Wave Observatory (LIGO) and the Virgo interferometric gravitational-wave detector of the European Gravitational Observatory (EGO) near Pisa, Italy, have agreed to join in a collaborative search for gravitational waves from sources in and far beyond our galaxy.]]> Advertise in this newsletter or website click for advertising kit - PDF File
