New View of Family Life in the North American Nebula

I found this article to be very interesting because it relates to what we are currently talking about in class, the nebular theory and the formation of stars and planets.
NASA's space telescope, Spitzer, gives us an infrared view of the North American nebula, named for its shape in visible light. In this view much more can be see than in visible light, including thousands of potential young stars. Luisa Rebull, from California Institute of Technology, and her team have discovered 2,000 candidate new stars forming in the nebula.
The article then goes on to explain how stars and planets form (but of course we should all already know how that happens), and tells that Spitzer allows us to see stars in all stages of development. I think it very cool that we can see an example of the nebular theory at work.
Here’s the link to the article http://www.nasa.gov/mission_pages/spitzer/news/spitzer20110210.html

I also thought that this article was very interesting and it was cool to apply what we have learned in class to different articles and be able to understand the content in them. This article also was interesting because it applied aspects of light that we learned about a couple of weeks ago. For example the article mentions that the Spitzer telescope took the infrared images at 3.6, 8, and 24 microns which corresponds to different colors such as blue, green, and red respectfully. We now know that as the wavelength of light increase the color changes from violet to red and this is evident in the article. Overall, I thought that it was interesting to see what we learned being applied in actual astronomical research.
