Supernova explosion that staged the new threats facing the Earth.

<P> According Technology Channel [http://tech.] 2008 年 1 月 10 reported: American Life Science Network reported, our Milky Way Eta Carinae (Eta Carinae) showed signs of going to explode, is to .an incredible speed of its nuclear fuel consumption, to its ultimate explosive demise quickly the fate and evolution as a supernova. .</ P> <P> period of at least the universe is, quiet for a while the Eta Carinae has long been difficult to contain their passion, while ready to start the next outbreak. .However, Eta Carinae's mass is 150 times the mass of the sun, and only 7,500 light years from Earth, so when Eta Carinae explosion, mankind can be seen from the Earth a spectacular "fireworks" .Perhaps enough and the moon in brightness comparable. .</ P> <P> doomed </ P> <P> Eta Carinae is a mysterious, extremely bright and unstable star. .1838-1858 years, Eta Carinae had a big outbreak, spraying out the sun 10 times the quality of the material, light enough to compete with Sirius as the brightest star in the sky. .Thought that the outbreak will be the torn to pieces but somehow Eta Carinae survived, survived. .Since 1940, lighten it again, scientists believe that Eta Carinae will detonate in 1,2 million years, into a supernova. .</ P> <P> Typically, supernova threat to life on Earth is very small, but the recent outbreak of the Earth is from the exception to the outbreak of objects may be only 30 light years from Earth, or even more recent, and its quality is the mass of the sun .150 times, enough to trigger a violent explosion. .Even more alarming is this: If the explosion 100 times brighter than normal, then life on Earth will face the danger of what? .Such a huge explosion from the earth if too close to enough to destroy all life on Earth, including humans. .</ P> <P> Eta Carinae's explosion is moving toward the final death </ P> <P> </ P> <P> the United States discovered a stone: on the left of the constellation Scorpio, the right is a star, may be .AD 1006 to record the supernova explosion </ P> <P> 2007 年 5 月 NASA observed the brightest ever recorded supernova explosion </ p>.
