If you were to invent a self-cleaning fabric, the world may want to beat a path to your door to buy some from you, but first of all they will have to know that the fabric exists, that it is available for purchase, and they have to be aware of where your door is. This means advertising.

How much information on astronomy should there be for all the objects and phenomenon in the entire universe? Consider that there are somewhere around 1 x 10 ^22 stars in the universe, that’s a one followed by 22 zeros. Then consider that many of those stars have planets revolving around them. Then consider all the moons that orbit those planets, then the comets and asteroids, the galaxies these stars form, the nebulae and black holes and everything else out there. The amount of information and data is staggering. This article, which presents astronomy facts, certainly won’t contain every fact. But these are quite interesting facts nevertheless.

Astronomy is a very exact science, although many people get involved with it when they are quite young. Astronomy is a thought-provoking hobby that can teach children about the sciences in general. A number of astronomical subjects interest kids and movies like Star Wars and they only serve to increase this attraction.
