CERN News: The Large Hadron Collider (LHC) sets collision record – new era in the history of particle physics. Spotlight on CERN – LHC First Physics — On March 30th 2010, first high-energy collisions took place at 7 TeV in the LHC, creating a phenomenal quantity of data. This not only marked the start of a new era for particle physics but also presents an enormous challenge in the field of computing, in terms of data transfer, storage and processing. — Please subscribe to Science & Reason: • www.youtube.com • www.youtube.com • www.youtube.com — The Large Hadron Collider (LHC) is the world’s largest and highest-energy particle accelerator, a synchrotron intended to collide opposing particle beams of either protons at an energy of 7 trillion electronvolts (1.12 microjoules) per particle, or lead nuclei at an energy of 574 TeV (92.0 µJ) per nucleus. The term hadron refers to particles composed of quarks. It is expected that it will address the most fundamental questions of physics, advancing our understanding of the deepest laws of nature. The LHC lies in a tunnel 27 kilometres (17 mi) in circumference, as much as 175 metres (574 ft) beneath the Franco-Swiss border near Geneva, Switzerland. The Large Hadron Collider was built by the European Organization for Nuclear Research (CERN) with the intention of testing various predictions of high-energy physics, including the existence of the hypothesized Higgs boson and of the large family of new particles predicted by …

NASA Renames Observatory for Fermi, Reveals Entire Gamma-Ray Sky. NASA’s newest observatory, the Gamma-ray Large Area Space Telescope, or GLAST, has begun its mission of exploring the universe in high-energy gamma rays. The spacecraft and its revolutionary instruments passed their orbital checkout with flying colors. NASA announced today that GLAST has been renamed the Fermi Gamma-ray Space Telescope. The new name honors Prof. Enrico Fermi (1901 – 1954), a pioneer in high-energy physics. “Enrico Fermi was the first person to suggest how cosmic particles could be accelerated to high speeds,” said Paul Hertz, chief scientist for NASA’s Science Mission Directorate at NASA Headquarters in Washington. “His theory provides the foundation for understanding the new phenomena his namesake telescope will discover.” Scientists expect Fermi will discover many new pulsars in our own galaxy, reveal powerful processes near supermassive black holes at the cores of thousands of active galaxies and enable a search for signs of new physical laws. For two months following the spacecraft’s June 11 launch, scientists tested and calibrated its two instruments, the Large Area Telescope (LAT) and the GLAST Burst Monitor (GBM). The LAT team today unveiled …

Q-The Universe Supernovas pt 1

Posted by SpaceMan in Supernova on 03 18th, 2010 | no responses

A supernova (pl. supernovae) is a stellar explosion that is more energetic than a nova. Supernovae are extremely luminous and cause a burst of radiation that often briefly outshines an entire interstellar , before fading from view over several weeks or months. During this short interval a supernova can radiate as much energy as the Sun is expected to emit over its entire life span.[1] The explosion expels much or all of a star’s material[2] at a velocity of up to 30000 km/s (a tenth the speed of light), driving a shock wave[3] into the surrounding interstellar medium. This shock wave sweeps up an expanding shell of gas and dust called a supernova remnant.
