Burning asteroids may play 'more important climate role than previously recognized'
Dust from asteroids entering the atmosphere may influence Earth's weather more than previously believed, researchers have found. view more (2005-08-26)
Cosmic dust in farthest quasar clue to early star formation
UK astronomers using the 15-m James Clerk Maxwell Telescope in Hawaii have discovered enormous quantities of cosmic dust in the most distant quasar yet observed. The quasar, called SDSS J1148+5251 is at a redshift (z) of 6.43, and is found in the direction of the constellation of Ursa Major. It is some 13 billion light years away, and we are... view more...

Physicists find evidence for highest energy photons ever detected from Milky Way's equator
Physicists at nearly a dozen research institutions, including New York University, have discovered evidence for very high energy gamma rays emitting from the Milky Way, marking the highest energies ever detected from the galactic equator. view more (2005-12-14)
Messy Bedroom Could Spell End For Creepy Crawlies
While children across the country are still trying to stick to their New Year's resolutions to tidy their bedrooms every morning, building scientists are investigating whether a clutter could actually be the key to healthier living. Dr Stephen Pretlove, from Kingston University's School of Architecture, is one of a group of specialists advising... view more... (2005-01-17)
Saharan dust storms sustain life in Atlantic Ocean
Research at the University of Liverpool has found how Saharan dust storms help sustain life over extensive regions of the North Atlantic Ocean. view more (2008-07-21)
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)
Disks around Failed Stars - a Question of Age
First Ground-Based Mid-Infrared Observations of Brown Dwarfs [1] A team of European astronomers [2] have observed eight Brown Dwarfs, i.e., small and faint objects also known as "failed stars", with the TIMMI2 infrared sensitive instrument at the ESO 3.6-m telescope on La Silla. From two of these, mid-infrared radiation is detected - for the first... view more... (2002-08-01)
Predicted Planet Seen-First Since Neptune 162 Years Ago
In 2006, astronomer Alice Quillen of the University of Rochester predicted that a planet of a particular size and orbit must lie within the dust of a nearby star. That planet has now been photographed by the Hubble Space Telescope, making it only the second planet ever imaged after an accurate prediction. view more (2008-12-10)
Astronomers find stellar cradle where planets form
Astronomers at the University of Illinois have found the first clear evidence for a cradle in space where planets and moons form. view more (2007-11-30)
Standardized house dust aids health researchers
Chemists at the National Institute of Standards and Technology (NIST) have created a standardized form of common house dust to support environmental scientists studying our everyday exposure to a catalog of potentially hazardous chemicals. view more (2007-02-02)
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)
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)
Infrared Echoes Give NASA's Spitzer a Supernova Flashback
Hot spots near the shattered remains of an exploded star are echoing the blast's first moments, say scientists using data from NASA's Spitzer Space Telescope. view more (2008-10-02)
House dust mite project aims to reduce asthma
A promising new way of controlling the mites that can cause asthma and other allergies is now under development. It could lead to dramatic progress in preventing these conditions and reduce the estimated £700 million a year spent in the UK on treating them. The technique uses a computer model to assess how modifying a domestic environment... view more... (2004-02-05)
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)
And now the weather ... on Mars
Blinding dust storms can seriously ruin your plans for a landing on Mars. ESA is adapting the global climate models that we use to forecast our weather on Earth for the turbulent conditions that Mars offers its future visitors. You could hardly call the weather on Mars pleasant, and presently it is far from predictable. As well as having an... view more... (2002-07-03)
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)
Sign of 'Embryonic Planets' Forming in Nearby Stellar Systems
Astronomers at the University of Rochester are pointing to three nearby stars they say may hold "embryonic planets"-a missing link in planet-formation theories. view more (2007-10-02)
Evidence for more dust than ice in comets
Observations of Comet 9P/Tempel 1 made by ESA's Rosetta spacecraft after the Deep Impact collision suggest that comets are 'icy dirtballs', rather than 'dirty snowballs' as previously believed. view more (2005-10-14)
Voracious black holes hide their appetite in dusty galaxies
A UK-led team of astronomers reports that they have tracked down an elusive population of black holes growing rapidly hidden behind clouds of dust. view more (2005-08-08)
