Homework Help: Science

Posted by Sara on Monday, February 22, 2010 at 7:23pm.

with 1*10 to the power of 22 stars in the sky. I can't put 22 in small form above 10, so that's why I'm wording it by saying to the power. So:

with 1*10 to the power of 22 stars in the sky. List several factors that limit us to being able to see only about 2000 to 3000.

*shape of the galaxy
*size of the galaxy
*The sun's light
*light reflection from earth

These are the only factors I've come up with, more help would be appreciated, thanks
