The Milky Way galaxy is threatened in Hit Giant Cloud, Clots containing a giant cloud of hydrogen gas in the middle of a very large volume disc bolted approaching the Milky Way, where our Solar System belongs. Devastating collision is expected to occur between 20-40 million years would generate a huge fireworks spectacular at the same time destroy all forms of life. The object is named Awan Smith, named GailSmith, a US astronomer who first detected in 1963 while researching at the University of Leiden, Belanda.Sejak discovered, astronomers are still debating whether the clouds are really approaching the Milky Way or away from it. Data records that have so far been limited and it is not clear whether the object is a part of the Milky Way or the fog is still moving toward him. So far, the researchers detected only gas and no single star in it. The only way melihtanya round by radio telescopes because of the cold gas does not emit light, but reflects radio waves. When viewed from Earth, the clouds width comparable to 30 times the width of the Moon. From the head to the tip of its tail is enough to envelop the constellation Orion. The new observations using radio telescopes in control most of the world, the Green Bank Telescope (GBT) in West Virginia, US, indicates that the object is moving toward the Milky Way galaxy. In fact, as reported by a combined team of astronomers from the US National Radio Astronomy Observatory (NRAO) and the University of Wisconsin Whitewater in the meeting of the American Astronomical Society to-211 in Austin, Texas recently, the driving force has touched the mist of the Milky Way. "If a collision occurs, it will trigger the birth of new star formation. There will be many giant stars are formed, short-lived, and exploded as a supernova that emit blinding light," said the team leader, DR. Felix Lockman, from the NRAO. Because, Cloud Smith brings enormous energy in the form of hydrogen gas enough to form millions of sun-sized star. Smith is a gas cloud clumps measuring 11,000 light-years long and 2,500 light-years wide. The object is currently located 40,000 light-years from Earth and 8,000 light years from the disk Bimasakti.Objek deserve the mist monsters in this cosmos space moving at a speed of 240 kilometers per second and is expected to hit the disc of the Milky Way galaxy with a slope of 45 degrees. Collisions will occur at the edge of the disk of the Milky Way almost the same distance to the center of our solar system to the distance to the center of the galaxy. However, the position is far from our solar system, is expected within 90 degrees towards the center of the dish. "We do not know where it came from, let alone its orbit confusing, but we say that she begins to interact with the outer parts of the Milky Way," said Lockman.
