APOD 3.4


The constellation Orion is 16,000 light years away and it contains mass amounts of dust particles. These dust particles were made in the outer atmospheres of very large cool stars.  A cool star, or carbon star is made up of more carbon than oxygen and is similar to a red giant. Another forming star cluser, Trapezium, is also found in this nebula. The Orion nebula is very active right now and is therefore producing more of these dust particles as stars are cooling down.
