laodan rated 8 months ago- A Galactic Star Forming Region in Infrared in Nasa's Astronomy Picture of the Day
Credit: S. Carey (SSC/Caltech), JPL-Caltech, NASA Explanation: How do stars form? To help study this complex issue, astronomers took a deep image in infrared light of an active part of our Milky Way Galaxy where star formation is rampant. In IRDC G11.11-0.11, thick clouds of dust and gas are congealing into stars that are so dark that humans living there would see an empty night sky. The image, though, taken last year by the Spitzer Space Telescope in infrared light, shows vast glowing fields of gas and dust, indicating that much of this dust is heated by forming stars. The centers of some clouds, such as the snake-like structure on the upper left, are so thick and cold that they are dark even in infrared light. Many of the red dots are glowing dust shrouds centered on very young newly formed stars. The unusual red sphere below the snake is actually a supernova remnant, the glowing shell of a young star so massive it evolved rapidly and exploded. The region spans about 150 light years and lies about 10,000 light years away toward the constellation of Sagittarius.

There is no reason to limit our vision of reality to what our eyes give us to see. Reality is vaster than our personal environment. The image given by our eyes is the first degree image of reality. It is the level at which individuals strive to reproduce their existence. But this first degree reality has since long been thwarted by new dimensions opened to us by culture, economics, science and so on. Reality has thus developed in our consciousness as our being a tiny particle into an infinite whole. Finite or infinite fact is that the whole is simply unattainable to us particles. Within the confines of this understanding of our limitations realism takes indeed another form
