General Prize Shortlist Announced - Aventis Prizes for Science Books 2002
Schizophrenia, dust, scientific rivalry and life among the baboons of Africa are among the subjects covered in the shortlist for the General Prize of the Aventis Prizes for Science Books 2002. The shortlist for the General Prize, selected from 83 entries submitted this year, is: AEONS by Martin... view more... (2002-05-24)
Young supernova remnants not dusty enough, according to UC Berkeley astronomers
One of the youngest supernova remnants known, a glowing red ball of dust created by the explosion 1,000 years ago of a supermassive star in a nearby galaxy, the Small Magellanic Cloud, exhibits the same problem as exploding stars in our own galaxy: too little dust. view more (2006-06-07)
Dusty old star offers window to our future, astronomers report
Astronomers have glimpsed dusty debris around an essentially dead star where gravity and radiation should have long ago removed any sign of dust - a discovery that may provide insights into our own solar system's eventual demise several billion years from now. view more (2005-09-09)

Treasures reborn out of dust
A day at a museum often forms part of vacationers' sightseeing plans. Greece has many famous sites of antiquity, where visitors can admire marble busts and statuary. It has become standard practice to protect the valuable, antique specimens against inquisitive fingers or polluted air by displaying almost indistinguishable, hand-made replicas. In a... view more...

Mobile climate monitoring facility to sample skies in Africa
The U.S. Department of Energy's Atmospheric Radiation Measurement (ARM) Program is placing a new, portable atmospheric laboratory with sophisticated instruments and data systems in Niger, Africa, to gain a better understanding of the potential impacts of Saharan dust on global climate. view more (2006-01-19)
Stellar Clusters Forming in the Blue Dwarf Galaxy NGC 5253
Star formation is one of the most basic phenomena in the Universe. Inside stars, primordial material from the Big Bang is processed into heavier elements that we observe today. In the extended atmospheres of certain types of stars, these elements combine into more complex systems like molecules and dust grains, the building blocks for new planets,... view more...

Hubble sees 'Comet Galaxy' being ripped apart by galaxy cluster
There are many galaxies of different shapes and sizes around us today. Roughly half are gas-poor elliptical-shaped galaxies with little new star formation activity, and half are gas-rich spiral and irregular galaxies with high star formation activity. Observations have shown that gas-poor galaxies are most often found near the centre of crowded... view more... (2007-03-05)
NASA Scientists Pioneer Method for Making Giant Lunar Telescopes
Scientists working at NASA's Goddard Space Flight Center in Greenbelt, Md., have concocted an innovative recipe for giant telescope mirrors on the Moon. To make a mirror that dwarfs anything on Earth, just take a little bit of carbon, throw in some epoxy, and add lots of lunar dust. view more (2008-06-05)
Saturn's rings show evidence of a modern-day collision
Scientists on NASA's Cassini mission have spied a new, continuously changing feature that provides circumstantial evidence that a comet or asteroid recently collided with Saturn's innermost ring, the faint D ring. view more (2006-10-12)
Colors of Quasars Reveal a Dusty Universe
The vast expanses of intergalactic space appear to be filled with a haze of tiny, smoke-like "dust" particles that dim the light from distant objects and subtly change their colors, according to a team of astronomers from the Sloan Digital Sky Survey (SDSS-II). view more (2009-02-26)
Tiny diamonds on Santa Rosa Island give evidence of cosmic impact
Nanosized diamonds found just a few meters below the surface of Santa Rosa Island off the coast of Santa Barbara provide strong evidence of a cosmic impact event in North America approximately 12,900 years ago. view more (2009-07-22)
Double-checking for cleanliness
Spotless surfaces are of prime importance in the plastics and metal processing industries, as dust and dirt can impair the function and adhesive properties of parts. A portable measuring device, the KombiSens, can detect both types of contamination. view more (2004-10-25)
Scientists track impact of Asian dust and pollution on clouds, climate change
Scientists using one of the nation's newest and most capable research aircraft are launching a far-reaching field project this month to study plumes of airborne dust and pollutants that originate in Asia and journey to North America. view more (2007-04-20)
Worlds in collision
Two terrestrial planets orbiting a mature sun-like star some 300 light-years from Earth recently suffered a violent collision, astronomers at UCLA, Tennessee State University and the California Institute of Technology will report in a December issue of the Astrophysical Journal, the premier journal of astronomy and astrophysics. view more (2008-09-24)
Tornado-like rotation is key to understanding volcanic plumes
A 200-year-old report by a sea captain and photographs of the 2008 eruption of Mount Chaiten are helping scientists better understand strong volcanic plumes. view more (2009-03-26)
How the Moon produces its own water
The Moon is a big sponge that absorbs electrically charged particles given out by the Sun. These particles interact with the oxygen present in some dust grains on the lunar surface, producing water. view more (2009-10-15)
Asteroids: treasures of the past and a threat to the future
If a large asteroid such as the recently identified 2004 VD17 - about 500 m in diameter with a mass of nearly 1000 million tonnes-collides with the Earth it could spell disaster for much of our planet. view more (2006-04-04)
How intense will storms get? New model helps answer question
A new mathematical model indicates that dust devils, water spouts, tornadoes, hurricanes and cyclones are all born of the same mechanism and will intensify as climate change warms the Earth's surface. view more (2008-07-09)
UCSD researchers make first direct observations of biological particles in high-altitude ice clouds
A team of UC San Diego-led atmospheric chemistry researchers moved closer to what is considered the "holy grail" of climate change science when it made the first-ever direct detection of biological particles within ice clouds. view more (2009-05-18)
