First object in space

[alokmohan]

New observations from NASA's Spitzer Space Telescope strongly suggest that infrared light detected in a prior study originated from clumps of the very first objects of the universe. The recent data indicate this patchy light is splattered across the entire sky and comes from clusters of bright, monstrous objects more than 13 billion light-years away.<br /><br />"We are pushing our telescopes to the limit and are tantalizingly close to getting a clear picture of the very first collections of objects," said Dr. Alexander Kashlinsky of NASA's Goddard Space Flight Center, Greenbelt, Md., lead author on two reports to appear in the Astrophysical Journal Letters. "Whatever these objects are, they are intrinsically incredibly bright and very different from anything in existence today."<br /><br />Astronomers believe the objects are either the first stars — humongous stars more than 1,000 times the mass of our sun — or voracious black holes that are consuming gas and spilling out tons of energy. If the objects are stars, then the observed clusters might be the first mini-galaxies containing a mass of less than about one million suns. The Milky Way galaxy holds the equivalent of approximately 100 billion suns and was probably created when mini-galaxies like these merged.<br /><br />This study is a thorough follow-up to an initial observation presented in Nature in November 2005 by Kashlinksy and his team. The new analysis covered five sky regions and involved hundreds of hours of observation time.<br /><br />Scientists say that space, time and matter originated 13.7 billion years ago in a tremendous explosion called the Big Bang. Observations of the cosmic microwave background by a co-author of the recent Spitzer studies, Dr. John Mather of Goddard, and his science team strongly support this theory. Mather is a co-winner of the 2006 Nobel Prize for Physics for this work. Another few hundred million years or so would pass before the first stars would form, ending the so-called dark a

Like you said Alokmohan, they might be seeing some of the early stars in the Universe. Many astronomers believe that these massive early stars are what lead to the creation of galaxies. These stars may have been much larger than 1,000 suns, from what I've heard, they may have been the largest stars ever to exist in the Universe. They would have lived very short lives, dying off in titanic explosions! Explosions so massive, they might have given birth to many of the supermassive blackholes that are believed to exist in the centers of galaxies.<br /><br />I have heard the term the "dark age" of the Universe. It is theorized that the Universe became visible because it actually became transparent. In its early days, before it became transparent, the Universe was so hot that we are unable to see through it. This might very well be the reason why we will never be able to see the actual Big Bang! <div class="Discussion_UserSignature"> <p> </p><p><strong><font color="#ff0000">Techies: We do it in the dark. </font></strong></p><p><font color="#0000ff"><strong>"Put your hand on a stove for a minute and it seems like an hour.

After big bang everything was very hot,and then came radiation era.You can speculate no doubt.

of course the early objects (stars and galaxies) should be bigger and more bright due to stronger gravitation force in the early days of the universe and conversely in distant future they will be smaller and less bright than those existing today due to gravitation being weaker than we know it today<br /><br /><br />BTW the link is<br />http://www.spitzer.caltech.edu/Media/releases/ssc2006-22/release.shtml<br /><br />vanDivX <div class="Discussion_UserSignature"> </div>
