APOD 3.1

APOD 3.1 Witch Head Nebula: http://apod.nasa.gov/apod/ap120117.html
A reflection nebula reflects light from nearby stars. This nebula lies 1000 light years away and is associated with the bright star Rigel which is located in the constellation, Orion. The fine dust located in the With Head Hebula, reflects Rigel's light. The blue color this nebula appears to be is not only from the apparent blue color of the star but also because the dust can moer effecently reflect blue than red. This same effect is displayed in the blue sky every day, because of the molecules(nitrogen and oxygen) in the Earth's atmasphere.
