"Lighthouse" was born in the universe 100 million years old (Figure).

<P Align=center> Hot words: hostility of the notebook photographs the art of the seven gods of fraud is not easy work of Knowledge, </ P> <P align=center> </ P> <P> According to "New Scientist" and "National Geographic" .and other media reported on November 2, the United States Aeronautics and Space Administration (NASA) Spitzer Space Telescope recently captured odd ray of light, from the first formed after the Big Bang the first generation of stars. .These stars, called the universe, "eldest son", they may tell their own light 13.0 billion years after the later ones, the most is what the early universe. .</ P> <P> ★ 40 hours to catch a bunch of "gray light" </ P> <P> if compared to the vastness of the universe as a painting, it should be the future stars and galaxies, while infrared emanation during .is the background. .The background was this particular scientist called "the warehouse of all the stars", NASA Goddard Space Flight Center is captured from the background of cosmic ray of light the first stars. .</ P> <P> light come this thread is very difficult. .Because 13 billion years of expansion, the universe has now become infinite, so the early stars, especially the first generation of stars to light difficult to track. .The researchers used the most sensitive measurement method, using the Spitzer Space Telescope, staring intently 40 hours, only to find that "little green leaves red," the odd light. .It is from the bottom of 13 billion years ago, has illuminated the darkness of the universe completely, bringing the first light to the universe, called "gray light." .The California astrophysicist Richard - Ellis put it described as the dawn of the lighthouse. .</ P> <P> ★ "Lighthouse" was born in the universe 100 million years old </ P> <P> Alexander, author of the study, said the owner of this hue the first generation of stars in the universe, that is the universe " .eldest son. " .They are located Dragon constellation, formed in the universe is only about 100 million years old. .At that time, just past the big bang, the universe is only an infant baby. .</ P> <P> Although most early, but did not affect the formation of these stars, large-bodied 100 times bigger than the sun. .But their composition is very simple, but the Big Bang produced hydrogen, helium and lithium. .Hydrogen helium Lithium gathered together to form stars burn, the outbreak of a strong light. .It is precisely because of their high strength, light was only to see today's telescopes. .But only for a brief period of only hundreds of millions of years, these stars will burn fuel died, leaving only short-lived afterglow. .</ P> <P> ★ infancy of the universe like a fireworks display </ P> <P> researchers also found that the hue extends 10 million light-years, along with a lot of bright spots arranged. .It was a lot of stars traces. .Thus, the researchers believe that these stars have been super-galaxy clusters hold, they combined together, this thread was issued jointly infrared signal. .</ P> <P> "It reveals to us how the distribution of the early universe and how stars form in the information." Alexander said. .Ellis guess, from the intensity of light appears, the first stars is likely to be ignited simultaneously in different parts of the light, like fireworks as both bloom everywhere. ."That scene must be very spectacular!" Ellis lamented, "because before that, the universe is dark, only hydrogen clouds floating in the dark." </ P> </ p>.
