Bringing space down to Earth to explain how stars form
In a laboratory in Nottingham, scientists are now creating the uniquely harsh conditions encountered in interstellar space. In an environment where the pressure is only one ten billion billionth (one part in 10 to the power 13) of atmospheric pressure, and the temperature a mere 10 degrees above absolute zero, Dr Martin McCoustra and his... view more...

University of Hawaii at Manoa astronomers discover pair of solar systems in the making
Two University of Hawai'i at Mānoa astronomers have found a binary star-disk system in which each star is surrounded by the kind of dust disk that is frequently the precursor of a planetary system. view more (2009-07-01)
Dust in West up 500 percent in past 2 centuries, says CU-Boulder study
The West has become 500 percent dustier in the past two centuries due to westward U.S. expansion and accompanying human activity beginning in the 1800s, according to a new study led by the University of Colorado at Boulder. view more (2008-02-25)
Surprising telescope observations shake up galactic formation theories
A heavy form of hydrogen created just moments after the Big Bang has been found to exist in larger quantities than expected in the Milky Way, a finding that could radically alter theories about star and galaxy formation, says a new international study led by the University of Colorado at Boulder. view more (2006-08-15)
Hunting the Southern Skies with SIMBA
First Images from the New "Millimetre Camera" on SEST at La Silla A new instrument, SIMBA ("SEST IMaging Bolometer Array"), has been installed at the Swedish-ESO Submillimetre Telescope (SEST) at the ESO La Silla Observatory in July 2001. It records astronomical images at a wavelength of 1.2 mm and is able to quickly map large sky areas. In order... view more... (2001-08-30)
Meteorites discovered to carry interstellar carbon
Like an interplanetary spaceship carrying passengers, meteorites have long been suspected of ferrying relatively young ingredients of life to our planet. view more (2006-05-05)
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)
Research team says extraterrestrial impact to blame for Ice Age extinctions
What caused the extinction of mammoths and the decline of Stone Age people about 13,000 years ago remains hotly debated. Overhunting by Paleoindians, climate change and disease lead the list of probable causes. But an idea once considered a little out there is now hitting closer to home. view more (2007-09-25)
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)
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)
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)
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)
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)
Saturn's rings have own atmosphere
Data from the NASA/ESA/ASI Cassini spacecraft indicate that Saturn's majestic ring system has its own atmosphere-separate from that of the planet itself. view more (2005-08-18)
Rosetta begins its 10-year journey to the origins of the Solar System
Europe's Rosetta cometary probe has been successfully launched into an orbit around the Sun, which will allow it to reach the comet 67P/Churyumov-Gerasimenko in 2014 after three flybys of the Earth and one of Mars. During this 10-year journey, the probe will pass close to at least one asteroid. Rosetta is the first probe ever designed to enter... view more... (2004-03-02)
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)
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)
Orphan stars found in long galaxy tail
Astronomers have found evidence that stars have been forming in a long tail of gas that extends well outside its parent galaxy. This discovery suggests that such "orphan" stars may be much more prevalent than previously thought. view more (2007-09-21)
