Although there is no one who would claim to really know, the most commonly accepted estimate in on the order of 10^22 stars.
Edit: Ben is the only other person who has attempted to give you an estimate based on research, and he says 7 times more than I said. In numbers this large and uncertain, that isn't as bad a difference as it might sound. Which surprises me why I got two thumbs down. I don't see two other estimates based on a scientific consensus. "Billions and billions?" Even billions OF billions would be several orders of magnitude too small. "Millions"? That person doesn't have any idea at all. "Too many to count?" Of course. That's why we estimate, using what we know about stars and galaxies. "How much sand on the beach?" Really? Is that based on a disciplined effort?
How about this comparison? I did the math. The number of stars, (assuming 10^22), is about the number of grains of sand in a volume of the Sahara desert 100 miles wide, 200 miles long, and ten feet deep. If Ben's estimate is closer, then make it 700 mi. x 200 mi. x 10 feet.
Joehalfa, I won't dispute the recent 7 x 10^22, but that grains of sand nonsense is ridiculous. And whoever said that is really lazy. The math isn't that hard. It would be about 1/25th of the Sahara Desert. Yet I see numbers like yours bandied about all over the place. I don't think the people who make these estimates even try to get it right. They just want it to sound impressive. Or are they assuming that beaches and deserts have no depth?

According to a study by Australian astronomers there are about ten times as many stars as grains of sand on all the world's beaches and deserts. This would be 7 followed by 22 zeros or 70 sextillion.

1/0 stars are there in universe

Well, it is hard to say because there are infinite number of galaxies, and each one has millions and millions of stars. So, the right answer at this moment is: There are infinite stars,

take it this way.
space is so big
that our galaxy, is a tiny little speck, smaller than a pencil dot would be on a peice of paper. 99999 million times smaller. so technically.
so many stars, if you found out you'd die from the shock of it all.

"Billions and billions."
Of course, now we know, even that's an understatement. It's now thought to be around 70 sextillion (that's 7 followed by 22 zeros).

Millions in the sky and only a few on the earth. Can't really get into my opinions cause.........

Countless. And I challenge any one to prove me wrong.
