  An international team of astronomers has discovered an exotic planet that appears to be made of diamond orbiting a tiny star in our galaxy. The new planet, which is far denser than any other previously known, consists primarily of carbon.  However, its high density has led scientists to calculate the carbon must be crystalline, meaning a large part of the planet would effectively be diamond. "The evolutionary history and amazing density of the planet all suggest it is...

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 "cosmic clocks" called pulsars aren't perfect. "We now have a more fundamental understanding of how pulsars work," Dr Hobbs said. "We've shown that many pulsar characteristics are linked, because they have one underlying cause." Armed with this understanding, astronomers will find it easier to...

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. The discovery could give astronomers a new tool to study the powerful gravitational forces that shaped the universe. Pulsars--incredibly fast spinning collapsed stars--have been studied in great detail since their discovery in 1967. The extremely stable rotation of these 'cosmic clocks'...

PPARC -- Astronomers using the 76-m Lovell radio telescope at the University of Manchester's Jodrell Bank Observatory have discovered a very strange pulsar that helps explain how pulsars act as 'cosmic clocks' and confirms theories put forward 37 years ago to explain the way in which pulsars emit their regular beams of radio waves - considered to be one of the hardest problems in astrophysics. Their research, now published in Science Express, reveals a pulsar that is only 'on' for part of...

Jodrell Bank -- Astronomers of the University of Manchester's Jodrell Bank Observatory (UK) have led an international team which used the Parkes radio telescope in Australia to find a new kind of cosmic object which sends out radio flashes. These flashes are very short and very rare: one hundredth of a second long, the total time the objects are visible amounts to only about one tenth of a second per day. The discovery will be published in this week's issue of the journal Nature. Eleven...

Cornell -- The Milky Way's fastest observed pulsar is speeding out of the galaxy at more than 670 miles a second, propelled largely by a kick it received at its birth 2.5 million years ago. Using the Very Long Baseline Array (VLBA), 10 radio telescopes spanning 5,000 miles from Hawaii to the U.S. Virgin Islands, James Cordes, professor of astronomy at Cornell University, his former student Shami Chatterjee, now of the Harvard-Smithsonian Center for Astrophysics, and colleagues studied the...


Word of the Day
baudekin
  • A rich embroidered or brocaded silk fabric woven originally with a warp of gold thread.
'Baudekin' seems to be an alternative form of 'baldachin,' from the Italian 'Baldacco,' Baghdad, the city where the material was made.
