Startling Star Fact:

Did you ever watch and listen when someone lights a barbecue grill or turns on a stove? First you hear a sound like air leaking out, then WHOOSH!, the fire roars to life. That is a special kind of air, called gas.  Stars are great big balls of burning gas!  If you had a magic spacesuit that would protect you from fire, you could actually pass right through a star.

After millions of years, all the gas burns up, the star gets smaller and it contracts into a very small dense dark rock called a dwarf.  A speck of one of these dwarfs, the size of an M&M, weighs more than a dump truck full of boulders!
