Sun's direct role in global warming may be underestimated, Duke physicists report
At least 10 to 30 percent of global warming measured during the past two decades may be due to increased solar output rather than factors such as increased heat-absorbing carbon dioxide gas released by various human activities.   view more (2005-10-03)

New comet discovered in Canada
Rob Cardinal was looking for an asteroid, but ended up finding a comet. It is the first time a comet has been discovered at the University of Calgary's Rothney Astrophysical Observatory, which is located about 35 kilometres southwest of Calgary, and only the second Canadian discovery of a comet... view more (2008-10-15)

Scientists Find Giant Ring Encircling Exotic Dead Star
One of the most powerful eruptions in the universe might have spun an infrared ring around a rare and exotic star known as a magnetar, a highly magnetized neutron star and the remnant of a brilliant supernova explosion signaling the death throes of a massive star.   view more (2008-05-29)

Mars Express discovers aurorae on Mars
ESA's Mars Express spacecraft has for the first time ever detected an aurora on Mars. This aurora is of a type never previously observed in the Solar System.   view more (2005-06-10)

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... view more (2006-12-20)

Climate Change Affecting Earth's Outermost Atmosphere

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... 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... 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... view more (2007-05-30)

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)

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)

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... 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... view more (2001-05-03)

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... 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)

Researchers think pink to produce 'green' solar energy
When it comes to producing earth-friendly solar energy, pink may be the new green, according to Ohio State University researchers. Scientists here have developed new dye-sensitized solar cells, that get their pink color from a mixture of red dye and white metal oxide powder in materials that... view more (2007-07-31)

Special coating greatly improves solar cell performance
The energy from sunlight falling on only 9 percent of California's Mojave Desert could power all of the United States' electricity needs if the energy could be efficiently harvested, according to some estimates.   view more (2008-02-25)

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)

Ice sheets drive atmospheric carbon dioxide levels, inverting previous ice-age theory
In the early 20th century, Milutin Milankovitch, a leading astronomer and climatologist of the time, proposed that the Earth's ice-age cycles could be predicted because they correspond directly with routine changes in the Earth's orbit and its tilt over cycles of tens of thousands of years.   view more (2006-07-25)

Press invitation: Solar Sailing Ships Set To Soar
A Discussion Meeting on "Solar Sail Mission Applications" will be held on the morning of FRIDAY 10th MAY 2002 in the Lecture Theatre of the Geological Society, Burlington House, Piccadilly, LONDON. The meeting will bring together world-renowned experts on this revolutionary new form of... view more (2002-05-02)

Largest, brightest supernova ever seen may be long-sought pair-instability supernova
An exploding star first observed last September is the largest and most luminous supernova ever seen, according to University of California, Berkeley, astronomers, and may be the first example of a type of massive exploding star rare today but probably common in the very early universe.   view more (2007-05-08)

Solar System's Young Twin Has Two Asteroid Belts
Astronomers have discovered that the nearby star Epsilon Eridani has two rocky asteroid belts and an outer icy ring, making it a triple-ring system. The inner asteroid belt is a virtual twin of the belt in our solar system, while the outer asteroid belt holds 20 times more material. Moreover, the... view more (2008-10-28)

Dust-enshrouded star looks similar to our sun
