Star can make sound?!

Who:The stars and the French astronauts
What:The astronauts record the three stars that will make sound by using a space telescope and this technique is called stellar seismology.They use this kind of technique to do new kinds of way to look at stars.
Where:In the universe(in think, because the star is in the universe so...)
When:October 24, 2008
Why:
For star: I think they make noise is because of there size and the age they are.
For the astronauts: I think they want to try the new technique and they use it to find out that star can make noise.

My Three FAT questions:


Why: Why are the stars are making sound (even i answer the question before but it's what i think, I want to know the real answer)d
How: How did the star make sound?
Where: My where here is that I want to know where did the star send the sound here.
