Since its construction in 1977 until the day of their first real test and launched on September 10, 2008.
teaches us briefly as it was built, from the start and early partner countries until the day that a beam of hadrons gave his first return to the 27 km circumference of the LHC in Geneva.

Photography damage

Unfortunately a weld in one sector lead to breakage in several dipole magnets and this has caused a fault that in addition to economically costly has caused the delay in the actual implementation of the LHC until next summer 2009.

LEP Large Electron-Positron collider

Large Electron Positron collider
LEP (Large Electron-Positron Collider) was an accelerator-collider e + e-circular for about twenty miles long, located a hundred meters underground on the border between France and Switzerland. Currently being replaced by the LHC. It was the last step of the complex of accelerators at CERN, and in it the electrons and positrons were injected and accelerated to final energy of a collision by using RF cavities. A dipole magnet system curved beams of electrons and positrons forcing them to follow a circular path.

The LEP, electrons and positrons circulating in opposite directions at relativistic speeds, grouped in bundles (bunches) of approximately 1.6 cm in length and a section of 0.3 × 0.01 mm2.

collision There were eight points, four of whom had installed two separate experiments: ALEPH, DELPHI, L3 and OPAL.

LEP began operation in August 1989 and although originally designed for the production of Z0 bosons (whose mass is 91.2 GeV/c2) with beam energies the first phase scheduled for around 45 GeV and luminosities of 1031 cm-2 · s-1, the various improvements in recent years been introduced into it (including the installation of superconducting cavities) allowed achieving beam energies up to 104.5 GeV.

was called LEP 2 (also LEP200 or LEP-II) to the second phase of the accelerator LEP particle, where it has increased the collision energy in the center of mass above 130 GeV. This increase allowed the production of pairs of W ± and Z0 bosons. It was hoped that the successive increases accounted even reach the threshold of production of new particles, for example, the Higgs boson. The collision energies reached in the center of mass system for each year of operation, and the corresponding integrated luminosity collected in the DELPHI detector can be seen in the following table.

Thin Rings Around Polarized Saturn

How thin are the rings of Saturn?

brightness measurements from different angles have shown that Saturn's rings have approximately a kilometer thick, which makes them proportionately many times thinner than a razor .





The Cassini interplanetary robotic station currently in orbit around Saturn took another picture that highlights the thinness of the rings.
This artistic beauty image was taken early last month with an infrared light filter polarized.




of being alone in space, the unlit side of Saturn would be much darker.
However, the reflection of light on moons such as Enceladus and billions of small particles in the rings Saturn's giant offers an extremely bright cosmic sphere, an effect that is enhanced in polarized light. Source

On the other side 20minutos.es report: Shadows toothed rings of Saturn.

Scientists working in learning more about the rings of Saturn.

What is causing the unusual shadows toothed rings of Saturn? No one is sure yet.

As Saturn is near the equinox, the rings gradually teach only their thin edge the Earth and the Sun

As a result, Saturn's moon cast long shadows on the rings. An example is the elongated vertical shadow of Mimas we see in the picture. The series of short, jagged shadows that go diagonally, however, are more unusual.

is known that Saturn's rings are made of particles for hundreds of years, but these particles have escaped to always be portrayed.

is therefore particularly exciting that a preliminary hypothesis holds that these shadows are jagged silhouettes of temporary groups of particles temporarily bound by its own gravity.

NASA revealed images of a hand-shaped nebula

The images of star formation can be distinguished blue fingers seem to try to find a red tag

The last picture taken Space Telescope NASA's Chandra show extensive nebula whose shape resembles a human hand .



The images of star formation, as extension is 150 light years can distinguish blue fingers seem to try to reach a red cloud.



According to NASA, this strange way has its origin in the electrons and ions emitted by a pulsar , "a star that spins so quickly in the space creates complex and intriguing structures." Source
