Precise Radio Measurements Advance Gravitational Physics Columbia MO (SPX) Sep 02, 2009
Scientists using a continent-wide array of radio telescopes have made an extremely precise measurement of the curvature of space caused by the Suns gravity, and their technique promises a major contribution to a frontier area of basic physics. "Measuring the curvature of space caused by gravity is one of the most sensitive ways to learn how Einsteins theory ... read moreChandrayan I Mission Failure Setback For India
New Delhi, India (XNA) Sep 02, 2009Less than a year after its launch, India's first unmanned lunar mission, Chandrayan I, knocked off the country's endeavor to assert its power in space, after it lost radio contact with the mission control following a technical glitch believed to have been caused by a burst of sun spot activity. Though the state-run Indian Space Research Organization (ISRO) hailed the moon mission a "great ... more

Australia Opens New Astronomy Research Center
Canberra, Australia (XNA) Sep 02, 2009A multi-million dollar astronomy research center opened in Western Australia (WA) on Tuesday, with backers hoping it would boost the nation's bid to secure the world's largest telescope. The International Center for Radio Astronomy Research (ICRAR) is designed to underpin the country's campaign to build the Square Kilometer Array (SKA), which could one day help unlock the secrets of the ... more Astronomy Question Of The Week: How Can There Be Clouds In Space
Bonn, Germany (SPX) Sep 02, 2009There are many different kinds of clouds in space, but none of them have anything to do with what we know as clouds on Earth - which are made out of tiny droplets of water. Originally - before the invention of the telescope - astronomers referred to all the shining, extended structures without clearly defined edges that they saw in space as 'clouds' (nebulae in Latin). Since even ... more Warped Debris Disks Around Stars Are Blowin' In The Wind
Greenbelt MD (SPX) Sep 01, 2009The dust-filled disks where new planets may be forming around other stars occasionally take on some difficult-to-understand shapes. Now, a team led by John Debes at NASA's Goddard Space Flight Center in Greenbelt, Md., finds that a star's motion through interstellar gas can account for many of them. "The disks contain small comet- or asteroid-like bodies that may grow to form planets," ... more |

Cygnus X-1: Still A "Star"
Greenbelt MD (SPX) Aug 31, 2009Since its discovery 45 years ago, Cygnus X-1 has been one of the most intensively studied cosmic X-ray sources. About a decade after its discovery, Cygnus X-1 secured a place in the history of astronomy when a combination of X-ray and optical observations led to the conclusion that it was a black hole, the first such identification. The Cygnus X-1 system consists of a black hole with a ... more India suffers blow to space ambitions
Bangalore, India (AFP) Aug 29, 2009India's first moon mission, launched amid much fanfare last year, came to an abrupt end Saturday after controllers lost contact with the country's lunar craft, the national space agency said. India launched an unmanned satellite and put a probe on the moon's surface late last year in an event that the national space agency hoped would give the country international "brand recognition" in the ... more New Look At Gravity Data Sheds Light On Ocean And Climate
Pasadena CA (SPX) Aug 28, 2009A discovery about the moon made in the 1960s is helping researchers unlock secrets about Earth's ocean today. By applying a method of calculating gravity that was first developed for the moon to data from NASA's Gravity Recovery and Climate Experiment, known as Grace, JPL researchers have found a way to measure the pressure at the bottom of the ocean. Just as knowing atmospheric pressure a ... more |
