There heavens Fireworks Spectacular 20-40 Million Years Again



Giant clouds of hydrogen gas that contains huge volumes approaching the middle of the dish off the Milky Way galaxy, where our solar system are. Catastrophic collision could have occurred between 20-40 million years from now will yield spectacular fireworks in the sky.

Object named Smith's Cloud, taken from the name of Gail Smith, an American astronomer who first detected it in 1963 while researching at the University of Leiden, The Netherlands. Since found, astronomers are still debating whether the clouds are really close to or away from the Milky Way.

Recording the data available so far are still limited and it is unclear whether the object is part of the Milky Way or the fog is still moving toward it. So far, the researchers only detect the gas and none of the stars in it.
The only way to go round see it is by radio telescopes because of the cold gas does not emit light, but reflects radio waves.

When viewed from Earth, the cloud width is proportional to the width of the Moon 30 times. From head to tip of tail is enough to cover the Orion constellation.

New observations using radio telescopes controlled most of the world, the Green Bank Telescope (GBT) in West Virginia, USA, showed that the object is moving toward the Milky Way. In fact, as reported to the combined team of astronomers from the National Radio Astronomy Observatory, USA (NRAO) and the University of Wisconsin Whitewater in the American Astronomical Society meeting of the 211 in Austin, Texas recently, the force pushed the Milky Way has touched the fog.

"If a collision occurs, it will also trigger the birth of formation of new stars. There'll be plenty of giant stars are formed, short-lived, and explode as a supernova that emit blinding light," said research team leader, DR. Felix Lockman, from the NRAO.

Because, Cloud Smith brings enormous energy in the form of hydrogen gas is sufficient to form a million stars the size of the Sun. Smith is a cloud of gas cloud size reaches 11,000 years long and light 2500 light-years wide. The object is currently located 40,000 light years from Earth and 8000 light years from the Milky Way disk.

Objects worthy of monsters in the mist of this cosmos is moving at 240 kilometers per second and is expected to hit the Milky Way disk with a slope of 45 degrees. Collision will occur at the edge of the Milky Way disk is the distance to the center is almost equal to the distance of our solar system to the center of the galaxy. However, its position far from our solar system, is estimated at 90 degrees to the center of the disc.

"We do not know where it came from, let alone its orbit confusing, but we say that he began to interact with the outer Milky Way," said Lockman.
