It's filled with gas and "stardust." The gas clouds are only illuminated by the stars around the nebula. Inside the 24-lightyear wide nebula, there are young stars and possibly even stars being formed. Stars that are 30,000 years old are considered young. Think of it this way: our sun is middle aged at 4 billion years.]]> 2020-03-12 17:16:53 UTC https://padlet.com/1208356/d54uiuts5cg/wish/459365655 1208356 https://padlet.com/1208356/d54uiuts5cg/wish/459377537 The atoms in the nebula's gas are sulfur, hydrogen (ionized), and oxygen (ionized).]]> 2020-03-12 17:28:35 UTC https://padlet.com/1208356/d54uiuts5cg/wish/459377537
