Star Colors in Orion
February 11, 2011
This photo seemed especially fitting because of the current topic of study in class. It's funny that we were just studying about properties of stars and that their spectra are changed from different factors of interstellar space and movement of the stars, and that today's pictures talks about just that. Obviously the main difference in the stars of this picture are the different colors. The upper left star of the constellation Orion is red because that star is a red giant. The color difference is caused by the temperature difference of the stars. The red color means that the star is cool. The blue color corresponds to a very hot temperature. The color of the stars can be messed up with the interstellar dust particles and the gas. Sometimes, the color of the star will look completely different. Stars are so far away, yet they can shine thousands of light years away. The star of Betelgeuse is so large, that the orbit would reach out to Jupiter if it was superimposed in place of the Sun. Stars are amazing features of our Solar System that should have more time devoted to studying them.
