study, samples of comet dust collected by high-flying aircraft in the upper atmosphere have yielded an unexpectedly rich trove of relicts from the ancient cosmos.The stratospheric dust includes minute grains that likely formed inside stars that lived and died long before the birth of our sun, as well as material from molecular clouds in interstellar space.This "ultra-primitive" material likely wafted...

Toxins in coal-tar-based sealcoats in parking lots may be the culprit in contaminated house dust, according to a USGS study. PAHs - or polycyclic aromatic hydrocarbons - are large molecules found in oil, coal and tar deposits, and can have toxic effects. It's long been known that PAHs are often found in house dust; however, the specific sources of these PAHs are largely undetermined. Researchers found...

council which exposed 10 of its employees to asbestos dust has been fined £14,000.City of Edinburgh Council joiners found the white dust while cutting a hole through a door that had been removed from Castlebrae Community High School.There were about 10 members of staff in the workshop at the time, including three who were "very close", the city's sheriff court heard.The court was told that in February...

Star gazers should be in for a treat on Tuesday night as the Leonid meteor shower reaches its peak of activity.It is predicted that up to 40 meteors per hour could soar through the skies over Northern Ireland.Although the main meteor activity will happen in the skies above Asia, meteors travelling at 160,000 miles per hour should be visible as midnight approaches.Meteors, or shooting stars, are the...

Astronomers, using European Southern Observatory's (ESO's) 3.58-meter New Technology Telescope (NTT), are seeing through the opaque dust lanes of the giant cannibal galaxy Centaurus A, unveiling its "last meal" in unprecedented detail - a smaller spiral galaxy, currently twisted and warped.Centaurus A (NGC 5128) is the nearest giant, elliptical galaxy, at a distance of about 11 million light-years.One...

Where does it come from? Scientists in Arizona are reporting a surprising answer to that question, which has puzzled and perplexed generations of men and women confronted with layers of dust on furniture and floors. Most of indoor dust comes from outdoors. Their report is scheduled for the Nov. 1 issue of ACS' Environmental Science & Technology, a semi-monthly journal.In the study, David Layton and...
