At the Large Hadron Collider (LHC) in the high energy particle physics facility CERN near Geneva, in Switzerland, thousands of physicists from all over the world have built the next instrument that is going to help them decode the secrets of Nature: the ATLAS detector
While the world’s largest accelerator, the LHC, is preparing for the first collisions, CERN is already designing the next generation, and its name is CLIC – the Compact Linear Collider.
In the quest to find out what matter is made of and how its different components interact, high-energy physics needs very sophisticated instruments using technologies and requiring performance that often exceed what is available to industry. New technologies are developed to solve specific needs at CERN, but these technologies are often applicable outside the physics laboratories. The most well known technology coming from CERN is the World Wide Web (WWW), originally developed to solve the information sharing need between physicists and laboratories. This technology was made freely available to everyone and is today part of the everyday modern communication.
No matter if we look out in space or inside matter the world’s constituents remain the same. With the imminent start of the Large Hadron Collider (LHC), the world’s most powerful particle accelerator, we enter into a new area of particle physics. Any new discoveries could also be beneficial to the areas of astrophysics and cosmology, shedding light on our common understanding of the universe.
The surface of the Sun has a temperature at about 10,000 degree Fahrenheit, but the temperature in the corona is rising to millions of degrees. Although scientists have some ideas of what the temperature in the solar corona might be, there is no universal explanation yet.

Eight new mission proposals selected for ESA’s future scientific programme
Insight in the vortex-like flows in the Earth’s core of fluid metal, information on the electrical properties of the viscous mineral mass in the Earth’s mantle, estimates of the crustal thickness and its remnant magnetism, calculation of the heat flow from Earth’s interior to the bottom of ice caps, measurements of large-scale ocean currents, sounding of the temperature and humidity profiles in the atmosphere, mapping of the electron content in the upper atmosphere, scaling of the electric currents in outer space, detection of the high-energy particles in the radiation belts, estimates of the electric fields in the solar wind.
The Swarm satellite mission is designed to provide the best ever survey of the geomagnetic field and its temporal evolution. The mission, proposed by a European consortium led by the Danish National Space Center, is scheduled for launch in 2010.
The Earth is a giant magnet. This simple fact, established at the end of the 16th century, is essential to an understanding of the processes that give rise to the aurora or Northern (and Southern) Lights.
