5-Times Size of Earth: Giant Solar Tornado Caught In Rare NASA Tape

A giant solar tornado - five times the Earth's diameter - swirling at incredible speed of some 186,000 mph has been captured on video by NASA's Solar Dynamics Observatory. This is the first time giant solar twister has been caught on video. Solar tornadoes, known as solar prominences, are shaped by the sun's magnetic field and often occur during coronal mass ejections -- huge explosions of solar plasma. The speed of swirling solar gases can sometimes reach several thousand miles per hour. This 124,000-mile-tall tornado was filmed on September 25, 2011, but the video was only released to the public at the National Astronomy Meeting in Manchester (UK) on Thursday. Xing Li, an astronomer at Aberystwyth University in Wales, believes the finding is a "real gem of an event to fire the imagination, and it is a good way to study magnetic structures in the sun's atmosphere." Scientists believe that study of solar tornadoes will help understand the causes of space storms in general, which is still one of the great mysteries of our solar system.

The Large Hadron Collider (LHC) - The Big Bang Experiment

The Large Hadron Collider (LHC) is the world's largest and highest-energy particle accelerator . It is expected to address some of the most fundamental questions of physics, advancing the understanding of the deepest laws of nature. The LHC lies in a tunnel 27 kilometres (17 mi) in circumference, as deep as 175 metres (574 ft) beneath the Franco-Swiss border nearGeneva, Switzerland. This synchrotron is designed to collide opposing particle beams of either protons at an energy of 7 teraelectronvolts (7 TeV or 1.12 microjoules) per nucleon, or lead nuclei at an energy of 574 TeV (92.0 ┬ÁJ) per nucleus (2.76 TeV per nucleon). The term hadron refers to particles composed of quarks. 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 testing for the existence of the hypothesized Higgs boson and of the large family of new particles predicted by supersymmetry. It was built in collaboration with over 10,000 scientists and engineers from over 100 countries, as well as hundreds of universities and laboratories. Credit to Original Uploader
