Latest Gravitational wave Stories
In the June 25th issue of Science, CSIRO astronomer George Hobbs and colleagues in the UK, Germany and Canada report that they have taken a big step towards solving a 30-year-old puzzle: why the â€œcosmic clocksâ€ called pulsars arenâ€™t perfect.
An international team of scientists including University of British Columbia astronomer Ingrid Stairs has discovered a promising way to fine-tune pulsars into the best precision time-pieces in the Universe.
Advancing into the next frontier in astrophysics and cosmology depends on our ability to detect the presence of a particular type of wave in space, a primordial gravitational wave.
While airplane and rocket experiments have proved that gravity makes clocks tick more slowly â€“ a central prediction of Albert Einstein's general theory of relativity â€“ a new experiment in an atom interferometer measures this slowdown 10,000 times more accurately than before, and finds it to be exactly what Einstein predicted.
Astronomers using ESOâ€™s Very Large Telescope have detected, in another galaxy, a stellar-mass black hole much farther away than any other previously known.
Teamwork between gamma-ray and radio astronomers has produced a breakthrough in finding natural cosmic tools needed to make the first direct detections of the long-elusive gravitational waves predicted by Albert Einstein nearly a century ago.
The discovery of seventeen new millisecond pulsars was announced Dec 5 at the American Astronomical Society Meeting by scientists from the Naval Research Laboratory (NRL) Space Science Division and a team of international researchers.
Within a decade scientists could be able to detect the merger of tens of pairs of black holes every year.
An international group of scientists says it has defined the energy density of gravitational waves created immediately after the birth of the universe.
On Wednesday, Aug. 19, 2009, the National Science Foundation (NSF) will host a live webcast featuring University of Minnesota Physicist Vuk Mandic.
