A NEW STAR N O I T C U D O R T N I Deep in space a dust cloud churns Tiny specks of matter move in gases The mass swells in one spot The dust and gases gather together They collapse under their gravity The pressure makes a hot core 4
The hot core attracts more dust and gases They swirl around the core The core becomes hotter It becomes massive Eventually it forms a new star This is how our sun was born The sun is a star It took 50 million years for the sun to fully form This happens throughout the universe Stars are continually born grow old and die The dust and gases in space can create objects besides stars They also form planets moons asteroids and other space objects All matter on the sun and Earth came from space
