Unlocking the frozen secrets of comet Wild 2
Eleven months ago, NASA's Stardust mission touched down in the Utah desert with the first solid comet samples ever retrieved from space. Since then, nearly 200 scientists from around the globe have studied the minuscule grains, looking for clues to the physical and chemical history of our solar system. view more (2006-12-20)
Climate Change Affecting Earth's Outermost Atmosphere
Carbon dioxide emissions from the burning of fossil fuels will produce a 3 percent reduction in the density of Earth's outermost atmosphere by 2017 view more (2006-12-12)
Space Man Joins BBC Voyage Around The Solar System
A Kingston University space expert has been reaching out to the stars after lending his specialist knowledge to a major TV drama-documentary. Director of the University's Aerospace Research Centre Dr Chris Welch has been working with the makers of BBC One series, Space Odyssey: Voyage to the Planets, which hits our screens next month. The... view more... (2004-10-20)
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)
Magnetic field uses sound waves to ignite sun's ring of fire
Sound waves escaping the sun's interior create fountains of hot gas that shape and power a thin region of the sun's atmosphere which appears as a ruby red "ring of fire" around the moon during a total solar eclipse, according to research funded by the National Science Foundation (NSF) and NASA. view more (2007-05-30)
Caltech visiting associate champions the study of solar eclipses in the modern era
Championing the modern-day use of solar eclipses to solve a set of modern problems is the goal of a review article written by Jay Pasachoff, visiting associate at the California Institute of Technology (Caltech) and Field Memorial Professor of Astronomy at Williams College. view more (2009-06-11)
UW astronomer hits cosmic paydirt with Stardust
Scientists at the Johnson Space Center in Houston were excited and awed Tuesday by what they saw when the sample-return canister from the Stardust spacecraft was opened. view more (2006-01-19)
Cosmic connections: Imperial scientist locates the origin of cosmic dust
The research, published in the journal Geology, shows that some of the cosmic dust falling to Earth comes from an ancient asteroid belt between Jupiter and Mars. This research improves our knowledge of the solar system, and could provide a new and inexpensive method for understanding space. view more (2008-09-03)
Solar loops spring into view
Huge loops of very hot gas rising above the Sun`s surface vibrate with enormous energy at times of solar storms. This is the latest surprise from ESA`s flotilla of spacecraft - SOHO, Ulysses and the four Cluster satellites - with which scientists are trying to make sense of how disturbances on the Sun affect the Earth. As reported today at a... view more... (2002-06-13)
Mysterious carbon excess found in infant solar system
Astronomers detected unusually high quantities of carbon, the basis of all terrestrial life, in an infant solar system around nearby star Beta Pictoris, 63 light-years away. view more (2006-06-08)
'Ultra-primitive' particles found in comet dust
Dust samples collected by high-flying aircraft in the upper atmosphere have yielded an unexpectedly rich trove of relicts from the ancient cosmos, report scientists from the Carnegie Institution. view more (2009-11-03)
Chameleon particles from the Sun
The Sun emits electron-neutrinos, elementary particles of matter that have no electric charge and very little mass, created in vast numbers by the thermonuclear reactions that fuel our parent star. Since the early 1970s, several experiments have detected neutrinos arriving on Earth, but they have found only a fraction of the number expected from... view more... (2002-04-22)
Screaming CMEs Warn of Radiation Storms
A CME (Coronal Mass Ejection) is a solar body slam to our high-tech civilization. CMEs begin when the sun launches a billion tons of electrically conducting gas (plasma) into space at millions of miles per hour. view more (2007-05-29)
Discovery of a satellite around the transneptunian object 1998 WW31
Alain Doressoundiram (Observatoire de Paris) and Christian Veillet (CFH Institute) have just discovered that the transneptunian object 1998 WW31 is in fact a double object. It is during their multi-color photometry and recovery of transneptunian objects program that they made this discovery. This program is carried out on the Canada-France-Hawaii... view more...

ISO satellite investigates dust discs around stars
investigate the dust discs around normal stars. Those few stars which are surrounded by clouds of dust (our own Sun is surrounded by a dust cloud) would form a list of stars which might have orbiting planets - some of which may support life. These stars would be among the first to be investigated by future space missions searching for signs of... view more... (1996-10-31)
U of M physicist reads the history of the solar system in grains of comet dust
Four years ago, NASA's Stardust spacecraft chased down a comet and collected grains of dust blowing off its nucleus. When the spacecraft Comet Wild-2 returned, comet dust was shipped to scientists all over the world, including University of Minnesota physics professor Bob Pepin. view more (2008-01-04)
Bacteria reveal secret of adaptation at Evolution Canyon
Bacteria living on opposite sides of a canyon have evolved to cope with different temperatures by altering the make-up of their 'skin', or cell membranes. Scientists have found that bacteria change these complex and important structures to adapt to different temperatures by looking at the appearance of the bacteria as well as their genes. view more (2008-07-28)
Secrets of a Dark Cloud
SOFI (Son OF ISAAC) is a scaled-down copy of ISAAC, the major VLT instrument that has already produced spectacular observations. SOFI is a unique instrument for the study of extended objects like "Barnard 68 (B68)" because of its very sensitive infrared detector and unrivalled large field-of-view. view more (1999-07-02)
Smaller isn't always better: Catalyst simulations could lower fuel cell cost
Imagine a car that runs on hydrogen from solar power and produces water instead of carbon emissions. While vehicles like this won't be on the market anytime soon, University of Wisconsin-Madison researchers are making incremental but important strides in the fuel cell technology that could make clean cars a reality. view more (2009-09-18)
UCLA researchers develop new method for producing transparent conductors
Researchers at UCLA have developed a new method for producing a hybrid graphene-carbon nanotube, or G-CNT, for potential use as a transparent conductor in solar cells and consumer electronic devices. view more (2009-05-14)
