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)

The Milky Way shaped life on Earth
Frenzied star-making in the Milky Way Galaxy starting about 2400 million years ago had extraordinary effects on life on Earth.   view more (2006-11-15)

Los Alamos Observatory Fingers Cosmic Ray 'Hot Spots'
A Los Alamos National Laboratory cosmic-ray observatory has seen for the first time two distinct hot spots that appear to be bombarding Earth with an excess of cosmic rays. The research calls into question nearly a century of understanding about galactic magnetic fields near our solar system.    view more (2008-11-24)

Planets forming in Pleiades star cluster, astronomers report
Rocky terrestrial planets, perhaps like Earth, Mars or Venus, appear to be forming or to have recently formed around a star in the Pleiades ("seven sisters") star cluster, the result of "monster collisions" of planets or planetary embryos.   view more (2007-11-16)

ESA scientist discovers a way to shortlist stars that might have planets
Markus Landgraf of the European Space Agency and colleagues (*) have found the first direct evidence that a bright disc of dust surrounds our Solar System, starting beyond the orbit of Saturn. Remarkably, their discovery gives astronomers a way to determine which other stars in the Galaxy are most likely to harbour planets and allows mission... view more... (2002-02-15)

Dust may dampen hurricane fury
After more than a dozen hurricanes battered the Atlantic Ocean last year, scientists are wondering what-if anything-might be causing stronger and more frequent storms.   view more (2006-10-10)

Astronomers discover new radio signal using large balloon
A team of NASA-funded scientists, including two from UC Santa Barbara, have discovered cosmic radio noise that they find completely unexpected and exciting.   view more (2009-01-08)

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)

Auger Observatory links highest-energy cosmic rays with violent black holes
Scientists of the Pierre Auger Collaboration, which includes New York University Physics Professor Glennys R. Farrar, have concluded that active galactic nuclei are the most likely candidate for the source of the highest-energy cosmic rays that hit Earth.   view more (2007-11-09)

Tunguska catastrophe: Evidence of acid rain supports meteorite theory
The Tunguska event is regarded as one of the biggest natural disasters of modern times. On 30 June 1908 one or more explosions took place in the area close to the Tunguska River north of Lake Baikal. The explosion(s) flattened around 80 million trees over an area of more than 2000 square kilometres.   view more (2008-07-16)

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)

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)

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)

NASA'S Dirty Secret: Moon Dust
The Apollo Moon missions of 1969-1972 all share a dirty secret. "The major issue the Apollo astronauts pointed out was dust, dust, dust," says Professor Larry Taylor, Director of the Planetary Geosciences Institute at the University of Tennessee. Fine as flour and rough as sandpaper, Moon dust caused 'lunar hay fever,' problems with... view more... (2008-09-29)

Universe's oldest objects emerge from the background
The deepest reaches of space are permeated by a cloak of infrared radiation, an uneven energy swath generated by long-dead objects from the early universe.   view more (2006-12-20)

Tracing ultra-fine dust
Fine particle emissions have been the subject of heated debate for years. People who live near industrial plants see the smoke being discharged into the atmosphere and wonder how harmful it is.   view more (2009-10-06)

Red dust in planet-forming disk may harbor precursors to life
Astronomers at the Carnegie Institution have found the first indications of highly complex organic molecules in the disk of red dust surrounding a distant star.   view more (2008-01-04)
