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.
As a part of the International Year of Planet Earth the International Heliophysical Year started the first day of March. The project will focus on the interaction between the Earth’s atmosphere and outflow from the Sun and interstellar sources.
Are we alone in the universe? Not very likely! On one, or several of the billion celestial bodies in the Universe there has got to be some kind of life. Intelligent peoples like us might exist, although it may sound like utopia. However, how do we find out?
Nearly unaffected by all hindrances, billions of neutrinos reach the earth every second. They do not only reach us, and the earth, they also pass through us unaffectedly, even through the core of the globe, and ultimately come out on the other side and continue the travel through space. Neutrinos are extremely small elementary particles that have one very particular feature: a strong antipathy for interaction with other matter, and without electrical charge.
