Gravity attracts more of the dust together. The dust then becomes so heavy and hot that it turns into a Protostar. When more dust and heat gets to the center of the Protostar, nucleus fusion will begin and the star is then born to the universe. ]]> 2017-05-03 20:10:28 UTC https://padlet.com/158135/47wdi7rrshe6/wish/169790045 158135 https://padlet.com/158135/47wdi7rrshe6/wish/169791934 2017-05-03 20:18:20 UTC https://padlet.com/158135/47wdi7rrshe6/wish/169791934 158135 https://padlet.com/158135/47wdi7rrshe6/wish/169792141 1 year=150 billion stars

During it's lifeline, gravity will be trying to crush the star, while heat is trying to make it grow bigger. Gravity and the heat of the star will finally find a 'happy medium' and stay balanced until the star runs out of oxygen.]]> 2017-05-03 20:21:02 UTC https://padlet.com/158135/47wdi7rrshe6/wish/169792487 158135 https://padlet.com/158135/47wdi7rrshe6/wish/169793261 2017-05-03 20:25:21 UTC https://padlet.com/158135/47wdi7rrshe6/wish/169793261 158135 https://padlet.com/158135/47wdi7rrshe6/wish/169793544 2017-05-03 20:26:49 UTC https://padlet.com/158135/47wdi7rrshe6/wish/169793544 158135 https://padlet.com/158135/47wdi7rrshe6/wish/169793976 When the hydrogen runs out, the star's outside expands and becomes a red giant.]]> 2017-05-03 20:29:12 UTC https://padlet.com/158135/47wdi7rrshe6/wish/169793976 158135 https://padlet.com/158135/47wdi7rrshe6/wish/169794364 2017-05-03 20:31:46 UTC https://padlet.com/158135/47wdi7rrshe6/wish/169794364 158135 https://padlet.com/158135/47wdi7rrshe6/wish/169794598 When a main sequence star becomes a red giant, it can become 10x larger than the sun!]]> 2017-05-03 20:33:11 UTC https://padlet.com/158135/47wdi7rrshe6/wish/169794598 158135 https://padlet.com/158135/47wdi7rrshe6/wish/169794806 The star will start to produce iron, which will make the star collapse.
