The "Mountains of Creation"
This giant cloud of dust and gas in the Milky Way has been dubbed the "mountains of creation," where the dust and gas are brought together by gravity in the peaks to create new stars. IRAC measures the warm dust and sees through it to study the process of star formation. This image shows the eastern edge of a region known as W5, near the Perseus constellation 7,000 light-years away.
