This picture depicts the Orion Bullets, which are ionized iron atoms that are larger than Pluto's orbit around our sun. They were created from the explosion of a star creation. Their yellow colored cones are of the nebula's shock-heated hydrogen gas, that the bullets led out and away form the nebula itself. They are up to 1/5th of a light-year long. The bullets themselves are traveling hundreds of kilometers per second!
