Breakthrough astrophysics research may have established the hitherto mysterious source of exceptionally high-energy cosmic ray emissions, according to recently published research that culminates a project developed by a scientist at the U.S. Department of Energy's (DOE) Argonne National Laboratory.   view more (2007-11-12)

High-energy particles from violent black holes travel to Earth
Ultra-high-energy particles from just outside enormous, active black holes in nearby galaxies travel as far as 250 million light years to make it all the way to Earth, an international team of 400 physicists and astronomers from 17 countries reports in the Nov. 9 issue of the journal Science.   view more (2007-11-12)

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)

Rosetta closes in on Earth - a second time
ESA's comet chaser, Rosetta, is on its way to its second close encounter with Earth on 13 November. The spacecraft's operators are leaving no stones unturned to make sure Earth's gravity gives it the exact boost it needs en route to its destination.   view more (2007-11-09)

Astronomers discover record 5th planet around nearby star 55 Cancri
A team of American astronomers announced today (Tuesday, Nov. 6) the discovery of a record-breaking fifth planet around the nearby star 55 Cancri, making it the only star aside from the sun known to have five planets.   view more (2007-11-07)

Scientists enhance Mother Nature's carbon handling mechanism
Taking a page from Nature herself, a team of researchers developed a method to enhance removal of carbon dioxide from the atmosphere and place it in the Earth's oceans for storage.   view more (2007-11-07)

Setting stars reveal planetary secrets
Watching the stars set from the surface of the Earth may be a romantic pastime but when a spacecraft does it from orbit, it can reveal hidden details about a planet's atmosphere.   view more (2007-11-06)

How did chemical constituents essential to life arise on primitive Earth?
Experiments show that simple molecules can combine chemically rather than biologically to form the building blocks of DNA, the key component of all life forms. These processes might have taken place on primitive earth, but how they occur is an unsolved puzzle.   view more (2007-10-31)

Possible cosmic defect may be a window into the early universe
An unusual cold spot in the oldest radiation in the universe, the cosmic microwave background, may be caused by a cosmic defect created just after the Big Bang, a Spanish and U.K. research team has found.   view more (2007-10-26)

Seismologists see Earth's interior as interplay between temperature, pressure and chemistry
Seismologists in recent years have recast their understanding of the inner workings of Earth from a relatively benign homogeneous environment to one that is highly dynamic and chemically diverse.   view more (2007-10-26)

Mars With Ice, Shaken, Not Stirred
Mars, like Earth, is a climate-fickle water planet. The main difference, of course, is that water on the frigid Red Planet is rarely liquid, preferring to spend almost all of its time traveling the world as a gas or churning up the surface as ice.   view more (2007-10-26)

Chang'e-1 - new mission to Moon lifts off
A bold new mission to the Moon was launched today by the Chinese National Space Administration (CNSA). Chang'e-1 blasted off from the Xichang Satellite Launch Centre, Sichuan, atop a Long March 3A rocket.   view more (2007-10-25)

Scientists Estimate Mercury Emissions from U.S. Fires; West Coast and Southeastern States are Major Emitters
Forest fires and other blazes in the United States likely release about 30 percent as much mercury as the nation's industrial sources, according to initial estimates in a new study by scientists at the National Center for Atmospheric Research (NCAR).   view more (2007-10-18)

Satellites help ensure efficient use of pesticides
A new service, developed in the framework of an ESA-supported project, is using satellite images to compare agricultural crop sites across Europe in order to ensure the more efficient use of pesticides.   view more (2007-10-16)

European lead in reading past climates from ice cores
Climate change is a reality today, but how can we find out about the future dangers it poses" What we really need is a full record of the Earth's climate for several hundred thousand years, complete with samples of air from different epochs that can be taken to the lab for analysis.   view more (2007-10-12)
