Welcome to Stubbies in Space!

Here's a few facts about the sun:
 * The earth was made by the sun!
 * When the sun explodes in a few billion years it will grow super hot and incinerate all life on earth:(
 * The light from the sun is 8 minutes old

My Student Question is: What is the difference between a Protostar and a normal star and how do whe know about them? Here is a bit of information on stars and Protostars: [[image:[Nebulosa+Trifida.jpg]]Eagle Nebula
 * A Protostar is a star that is still being made
 * Good website: []
 * Look at this website it is good []
 * Our sun is 15 million degrees celcius
 * Stars are about 97% Hydrogen and about 3% Helium
 * Olds stars often shoot out gas and dust clouds that pull more dust and gas into itself
 * Class 0 protostars (the youngest type) are about10,000 to 100,000years into its life and about -260 degrees celcius
 * After a few million years a proto stars become a star!
 * It was first thought to be gravity that made a protostar out of a nebula but now it is thoght to be something else as well!
 * Stars have all once been a cloud of gas and dust and over millions of years the centre of the cloud becomes much more denseand pulled into a ball that turns super hot!
