Nebulae are clouds of interstellar gas and dust where stars can form. In this infrared image from NASA's Spitzer space telescope and 2MASS [Two Micron All Sky Survey], a nebula known as 'The Spider', officially named as IC 417, glows in fluorescent green lights. 

The Spider, located about 10,000 light-years from Earth in the constellation Auriga, is clearly a site of star formation. It resides in the outer part of the Milky Way, almost exactly in the opposite direction from the galactic center.

One of the largest clusters of young stars in the Spider can be seen easily in the image. Toward the right of center, against the black background of space, you can see a bright group of stars called Stock 8. 


The light from this cluster carves out a bowl in the nearby dust clouds, seen in the imageas green fluff. Along the sinuous tail in the center, and to the left, the groupings of red point sources clumped in the green are also young stars.

In this image, infrared wavelengths, which are invisible to the normal eye, have been assigned in visible colors.
