Endotoxins in cigarette smoke
A room where people smoke contains dozens or hundreds of times higher air concentrations of endotoxins than smoke-free indoor air. This has been shown by a research team from Lund University. Endotoxin is the name of a group of poisonous substances produced by bacteria and naturally occurring in the air and elsewhere. In normal low concentrations,... view more... (2004-08-19)
Comet dust brought back to Earth: paving the way for Rosetta
Scientists around the world eagerly await the arrival of sample particles from Comet Wild 2, which are being brought back to Earth by the US Stardust spacecraft on 15 January this year. view more (2006-01-13)
NASA Scientists Detect Spectrum of Planets Orbiting Other Stars
For the first time, scientists at Goddard have obtained a spectrum, or molecular fingerprint, of a planet orbiting another star. Using spectroscopy, scientists were able to identify silicon dust in clouds on a gas-giant planet called HD 209458b. That planet is located 150 light years from Earth. view more (2007-02-23)
Cosmic thermostats provide clue to 30 year old astronomy puzzle (Embargoed until 1900 hrs London time Wednesday 17 July 2002)
A cosmic phenomenon involving pockets of hot gas in space which appear not to cool down has been puzzling astronomers for three decades. Now new research by Dr Christian Kaiser at the University of Southampton and Professor Marcus Brüggen of the International University Bremen, Germany, shows that the energy of the hot gas is actually... view more...

Astronomers report unprecedented double helix nebula near center of the Milky Way
Astronomers report an unprecedented elongated double helix nebula near the center of our Milky Way galaxy, using observations from NASA's Spitzer Space Telescope. view more (2006-03-16)
Hubble sees the graceful dance of 2 interacting galaxies
A pair of galaxies, known collectively as Arp 87, is one of hundreds of interacting and merging galaxies known in our nearby Universe. Arp 87 was originally discovered and catalogued by astronomer Halton Arp in the 1970s. Arp's Atlas of Peculiar Galaxies is a compilation of astronomical photographs using the Palomar 200-inch Hale and the 48-inch... view more... (2007-10-31)
Supernovae-Cosmic Lighthouses
Supernovae stand out in the sky like cosmic lighthouses. Scientists at the Max Planck Institute for Astrophysics and at the National Astronomical Institute of Italy have now found a way to use these cosmic beacons to measure distances in space more accurately. view more (2007-02-12)
Eclipsing brown dwarfs provide new key to the star formation process
Pity the brown dwarf. It's too large to be a planet, but too small to be a star. view more (2006-03-16)
Carina Nebula dust pillars harbor embedded stars, says research team
Astronomers using NASA's Spitzer Space Telescope have imaged a giant molecular cloud being shredded by howling stellar winds and searing radiation, exposing a group of towering dust pillars harboring infant stars, according to a University of Colorado at Boulder researcher. view more (2005-05-30)
Even 'failed stars' form planets
An international team of astronomers shows that even brown dwarfs start to form planets. view more (2005-10-26)
Did dust bust the 2006 hurricane season forecasts?
A recent NASA study suggests that tiny dust particles may have foiled forecasts that the 2006 hurricane season would be another active one. view more (2007-03-29)
Chain mail for rockets, or protection in a grid
A program developed by Russian scientists under support from the International Science and Technology Center (Project 1917) helps to protect spacecraft from orbital debris that rushes at great speed, in the most effective and economic manner. view more (2005-03-03)
Scientists to 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 (2007-04-19)
Light echoes whisper the distance to a star
Taking advantage of the presence of light echoes, a team of astronomers have used an ESO telescope to measure, at the 1% precision level, the distance of a Cepheid - a class of variable stars that constitutes one of the first steps in the cosmic distance ladder. view more (2008-02-11)
A new unidentified very high energy gamma-ray source in our Galaxy
A European team based in Heidelberg (Germany) and their colleagues from the HEGRA collaboration have discovered a new, unidentified, very high energy gamma-ray source in our Galaxy. This source was detected via ground-based observations of the Imaging Atmosphere Cherenkov Telescope System. view more (2004-12-14)
Softening agent from PVC cause of asthma and allergic symptoms among children
There is a clear co-variation between allergic symptoms in children and the concentration of softening agents in their homes. This is a finding made by a Swedish-Danish research team in a recently published study financed by Formas, the Swedish Research Council for Environment, Agricultural Sciences, and Spatial Planning. "A great number of... view more... (2004-08-16)
Clouds: Lighter than air but laden with lead
By sampling clouds -- and making their own -- researchers have shown for the first time a direct relation between lead in the sky and the formation of ice crystals that foster clouds. view more (2009-04-20)
Clues To Supernova Origin Found In Dusty Stellar Wind
Scientists from Imperial College London have detected a dusty wind emitted by a star that, at the end of its life, turned into a white dwarf and then exploded as a supernova. This is the first time that a wind from this type of supernova precursor has been observed and it is also the first time that associated dust has been detected. The... view more... (2005-03-30)
Closer To The Monster
Trailblazing VLT Interferometer Studies of the Central Region in Active Galaxy NGC 1068 [1] Fulfilling an old dream of astronomers, observations with the Very Large Telescope Interferometer (VLTI) at the ESO Paranal Observatory (Chile) have now made it possible to obtain a clear picture of the immediate surroundings of the black hole at the centre... view more...

Mother's prenatal stress predisposes their babies to asthma and allergy
Women who are stressed during pregnancy may pass some of that frazzlement to their fetuses in the form of increased sensitivity to allergen exposure and possibly future asthma risk. view more (2008-05-19)
