Mapping large-scale cosmic structures will help test theories Pioneering observations with the National Science Foundation's giant Robert C. Byrd Green Bank Telescope (GBT) have given astronomers a new tool for mapping large cosmic structures. The new tool promises to provide valuable clues about the nature of the mysterious "dark energy" believed to constitute nearly three-fourths of the mass and energy of the Universe. Dark energy is the label scientists have given to what is causing the...

Hydrogen would command a key role in future renewable energy technologies, experts agree, if a relatively cheap, efficient and carbon-neutral means of producing it can be developed. An important step towards this elusive goal has been taken by a team of researchers with the U.S. Department of Energy's (DOE) Lawrence Berkeley National Laboratory (Berkeley Lab) and the University of California, Berkeley. The team has discovered an inexpensive metal catalyst that can effectively generate...

Imagine finding a living dinosaur in your backyard. Astronomers have found the astronomical equivalent of prehistoric life in our intergalactic backyard: a group of small, ancient galaxies that has waited 10 billion years to come together. These "late bloomers" are on their way to building a large elliptical galaxy. Such encounters between dwarf galaxies are normally seen billions of light-years away and therefore occurred billions of years ago. But these galaxies, members of Hickson Compact...

Several ways have been proposed to examine dark energy, in hopes of finding out just what it is. One of them, "supernovae" for short, certainly works: it's how dark energy was discovered in the first place. Other independent techniques, such as weak gravitational lensing and baryon acoustic oscillation, also promise great power but are as yet unproven.These three techniques all have a share of the proposed Joint Dark Energy Mission (JDEM), a satellite design managed by NASA with the...

The "coming of age" of galaxies and black holes has been pinpointed, thanks to new data from NASA's Chandra X-ray Observatory and other telescopes. This discovery helps resolve the true nature of gigantic blobs of gas observed around very young galaxies. About a decade ago, astronomers discovered immense reservoirs of hydrogen gas -- which they named "blobs" "“ while conducting surveys of young distant galaxies. The blobs are glowing brightly in optical light, but the source of immense...

Something vital is missing in the far distant reaches of the Universe: hydrogen - the raw material for stars, planets and possible life. The discovery of its apparent absence from distant galaxies by a team of Australian astronomers is puzzling because hydrogen gas is the most common constituent of normal matter in the Universe. If anything, hydrogen was expected to be more abundant so early in the life of the Universe because it had not yet been consumed by the formation of all the stars and...

As gas prices continue to soar to record highs, motorists are crying out for an alternative that won't cramp their pocketbooks.Scientists at U.S. Department of Energy's Argonne National Laboratory are answering that call by working to chemically manipulate algae for production of the next generation of renewable fuels "“ hydrogen gas."We believe there is a fundamental advantage in looking at the production of hydrogen by photosynthesis as a renewable fuel," senior chemist David Tiede...

CHAMPAIGN, Ill. -- Oxygen may be necessary for life, but it sure gets in the way of making hydrogen fuel cheaply and abundantly from a family of enzymes present in many microorganisms. Blocking oxygen's path to an enzyme's production machinery could lead to a renewable energy source that would generate only water as its waste product. Researchers at the Beckman Institute for Advanced Science and Technology at the University of Illinois at Urbana-Champaign have opened a window by way of...

Word of the Day
  • Remarkable; prodigious.
  • Audacious; gutsy.
  • Completely; extremely.
  • Audaciously; boldly.
  • Impressively great in size; enormous; extraordinary.
This word is probably from the dialectal 'boldacious,' a blend of 'bold' and 'audacious.'
