how many stars are there in the universe and if the universe infinite?

The other answers regarding star counts are accurate.  In fact, just like people, stars are dying and being born all over the universe.  Therefore an exact count would require omnicient overisght - there is no way a human being could know how many stars exist, are dying, and being born at one time.  \n\nWhile the universe has been thought to be infinite, or finite but really, really big, I like to conisder it finite with infinite ability for expansion.  Of course, based on its current expansion rate, the universe will eventually begin to collapse.

Brad is right; there are around 3000 stars visible to the naked eye at a given moment under good seeing conditions. There are around 8000 visible in the whole 4pi sky.\n\nOur galaxy, the Milky Way, contains about 10^11 (100 billion) stars. There are about 10^11 galaxies, so about 10^22 stars in the whole universe.

Many  astronomers think that the Universe is infinite. See, this\nwebsite for the complete explanations.

If your question is based on what you can see as well as are actually above us and that you are a young person with pupils that will dilate to ~ 7mm tops AND you are observing from a dark dark site with steady seeing conditions (very little "twinkling" of the observed stars)...I think around 15,000 "bright" (we won't get into "limiting magnitude" as that is a large variable) stars is a safe guess. However, technically due to the fact that the as you look towards the constellation Sagittarius in the summer from the N. hemisphere you are looking towards the center of the Milky Way (our galaxy name). That  splash of "cloud" is the combined light of (as C. Sagan would say) "billions and billions" of stars.\nThat latest estimation of our sister galaxy Andromeda is upwards of 300 billion stars alone (it's number of orbiting stars that are influenced and follow it's spin has just recently been upped quite a bit). The current estimate for the Milky Way is 250 billion...however it has also recently been re-classified as a "barred spiral" and no longer a pinwheel shape like "whirlpool spiral". So...who knows a re-estimation of it's star number content may change.\nIn general most galaxies average out to have between 200 - 300 billion stars.\n\nNow...if we take all the assumptions mentioned above (about your eyes, seeing conditions etc) and we add to the number 15,000 of bright individually distinguishable stars in the Milky Way and the number of stars represented by the glow of the Milky Way and the number of stars in the Andromeda galaxy (which a kids good eyes should be able to see ...no sweat) well then the number you can see goes...WAY UP... Carl Sagans answer is an understatement.

The total number of known stars is 10,000,000,000,000,000,000,000, when we write this number out. This figure would be pronounced as "ten billion trillion" stars.\n\nAs technology improves, this number will continue to increase since there are many more stars out there.

physically the universe has no limits . but still it is expanding with enormous speed . you can go to this link : http://en.wikipedia.org/wiki/Space and find out whatever you need about space . good luck

200 billion stars in the Milky Way.

According to the International Astronomical Union (the official policy making body for astronomers) there are 88 constellations.  Each constellation has its own 'border', and every object in the sky falls into one of those constellations.  The best picture I could find is below.  I hope this helped!

In the infinite universe it is very very likely that the number of Gods is infinite, too. Each God must have a God superior than herself. That is all to it. Either the Gods are limitless or there is no God at all. This is logic . The rest is nothing more than rubbish thinking or "feeling" as they might call it.....

The number of stars in the visible universe is estimated to be 70 sextillion, or 70,000,000,000,000,000,000,000 [seven followed by twenty-two zeros].\n\nor\n\nWikipedia claims that the observable universe contains about 7 × 1022 stars, organized in about 100 billion galaxies, which themselves form clusters and superclusters. An Ask the Scientist response to this question claimed that there are about 10 billion (10^10) stars in an average galaxy, \nand there are about 10 billion galaxies that we can observe in the universe, so the answer is 100 billion billion or 10^20. I don't think it is an issue that we have a precise answer for as yet.

Actually, they know it isn't infinite.\n\n\nThe findings are mostly thanks to hubbles big idea and discovery, but they can now confirm that indeed the visible universe is finite thanks to WMAP.\n\n\n\nAs for the possiblity of space outside of the visible universe...we have no idea.

Stars are not scattered randomly through space, they are gathered together into vast groups known as galaxies. The Sun belongs to a galaxy called the Milky Way. Astronomers estimate there are about 100 thousand million stars in the Milky Way alone. Outside that, there are millions upon millions of other galaxies also!  \n \n  \n \n \n Hipparcos mapped millions of stars in our galaxy, but how many more are there? \nIt has been said that counting the stars in the Universe is like trying to count the number of sand grains on a beach on Earth. We might do that by measuring the surface area of the beach, and determining the average depth of the sand layer. \n\nIf we count the number of grains in a small representative volume of sand, by multiplication we can estimate the number of grains on the whole beach. \n\nFor the Universe, the galaxies are our small representative volumes, and there are something like 1011 to 1012 stars in our galaxy, and there are perhaps something like 1011 or 1012 galaxies. \n\nWith this simple calculation you get something like 1022 to 1024 stars in the Universe. This is only a rough number, as obviously not all galaxies are the same, just like on a beach the depth of sand will not be the same in different places. \n\nNo one would try to count stars individually, instead we measure integrated quantitites like the number and luminosity of galaxies. ESA's infrared space observatory Herschel, to be launched in 2007, will make an important contribution by 'counting' galaxies in the infrared, and measuring their luminosity in this range - something never before attempted.

Unfortunately we do not have any concrete evidence.  Here is a good quote by the late Carl Sagan:\n\n"There are some hundred billion (1011) galaxies, each with, on the average, a hundred billion stars. In all the galaxies, there are perhaps as many planets as stars, 1011 x 1011 = 1022, ten billion trillion. In the face of such overpowering numbers, what is the likelihood that only one ordinary star, the Sun, is accompanied by an inhabited planet? Why should we, tucked away in some forgotten corner of the Cosmos, be so fortunate? To me, it seems far more likely that the universe is \nbrimming over with life. But we humans do not yet know. We are just beginning our explorations. The only planet we are sure is inhabited is a tiny speck of rock and metal, shining feebly by reflected sunlight, and at this distance utterly lost."

Ok, how about this:\n\nAstronomers estimate that there are at least 70 sextillion (7×10^22) stars in the known universe. That is 230 billion times as many as the 300 billion in our own Milky Way.\n\n(shamelessly stolen from Wikepedia)

There was a study done by a group of Australian astronomers where they calculated (somehow) that there are approximately 70,000 million million million (or 70,000,000,000,000,000,000,000) stars in the known Universe, which means these are just the ones that we can see with our telescopes.  This is supposed to be 10 times the number of grains of sand on all the beaches and deserts in the world.

Universe in general is the area of everything including earth, solar systems, nebulas, black holes, galaxies etc are contained within. Everything that is observable to us(human) are so far within this universe. So maybe there are more but to human.. there is only 1.

yes, there are infinte, the universe is infinite and besides that, there are infinite spacial-temporal or just temporal realities, not just one, not ten, not a million but infinite. Just imagine ! You should read The Fabric of Reality by David Deutsch. a great scientist in physics and , he is English, proffesor at Oxford I think.
