Advanced LIGO Project Funded By National Science Foundation 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. This major upgrade will increase the sensitivity of the LIGO instruments by a ... read more |

Plant Growth Experiment Starts In Columbus
Paris, France (ESA) Mar 05, 2008ESA 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. WAICO, short for Waving and Coiling of Arabidopsis Roots at Different g-levels, looks at the growth of two types of Arabidopsis seed. In all, two differ ... more Grad student invents a gravity clock
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. Clay Moulton of Springfield, Va., who received his master's of science degree last year from Virginia Tech, created the lamp as a part of his master's thesis. The LED lamp, named Gravia, is an acrylic column a little more than 4 feet high ... more A New Window On The Universe
Milwaukee WI (SPX) Nov 18, 2007Using 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 ... more Embry-Riddle And Zero Gravity To Collaborate On Weightless Flights
Daytona Beach FL (SPX) Nov 05, 2007Researchers, 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 m ... more Cluster And Double Star Pinpoint The Source Of Bright Aurorae
Paris, France (ESA) Sep 12, 2007Colourful 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. ... more |

Huntsville AL (SPX) Jun 06, 2007A 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). ... more Scientists Provide First Public Peek At Gravity Probe B Results
Jacksonville FL (SPX) Apr 17, 2007For 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. Today, at the American Physical Society (APS) meeting in Jacksonville, Fla., Professor Francis Everitt, a Stanford University physicist and principal investigator of the Gravity Probe B (GP-B) Relativity Mission, a c ... more LIGO And Virgo Join Forces In Search For Gravitational Waves
Pasadena CA (SPX) Mar 06, 2007The 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. The collaboration will link the three LIGO detectors, which are in the United States, and LI ... more Hubble Watches Comet Galaxy Ripped Apart By Galaxy Cluster
Baltimore MD (SPX) Mar 05, 2007The NASA/ESA Hubble Space Telescope, in collaboration with several other ground- and space-based telescopes, has captured a galaxy being ripped apart by a galaxy cluster's gravitational field and harsh environment. The finding sheds light on the mysterious process by which gas-rich spiral-shaped galaxies might evolve into gas-poor irregular- or elliptical-shaped galaxies over billions of years. ... more Gravity Helps SDSS-II Reveal A Brilliant Jewel Of The Early Universe
Chicago IL (SPX) Nov 09, 2006A team from the Sloan Digital Sky Survey (SDSS-II) and Fermi National Accelerator Laboratory today announced discovery of the brightest known image of a galaxy from the early universe. While furious star formation makes the galaxy luminous, it enters the record books because the gravity of a foreground galaxy acts as a natural telescope, focusing its light on the earth. The newly discovere ... more |

Paris, France (SPX) Mar 24, 2006Scientists funded by the European Space Agency have measured the gravitational equivalent of a magnetic field for the first time in a laboratory. Under certain special conditions the effect is much larger than expected from general relativity and could help physicists to make a significant step towards the long-sought-after quantum theory of gravity. Just as a moving electrical charge crea ... more
