FUSE

NASA’s FUSE (Far Ultraviolet Spectroscopic Explorer) mission observed the sky in far-ultraviolet light — wavelengths between about 90 to 120 nanometers — with greater sensitivity and resolving power than previous instruments. Over eight years of operations, FUSE acquired more than 6,000 observations of nearly 3,000 separate astronomical targets, including massive stars, supernova remnants, and galaxies.

The image is divided horizontally by an undulating line between a cloudscape forming a nebula along the bottom portion and a comparatively clear upper portion. Speckled across both portions is a starfield, showing innumerable stars of many sizes. The smallest of these are small, distant, and faint points of light. The largest of these appear larger, closer, brighter, and more fully resolved with 8-point diffraction spikes. The upper portion of the image is blueish, and has wispy translucent cloud-like streaks rising from the nebula below. The orangish cloudy formation in the bottom half varies in density and ranges from translucent to opaque. The stars vary in color, the majority of which have a blue or orange hue. The cloud-like structure of the nebula contains ridges, peaks, and valleys – an appearance very similar to a mountain range. Three long diffraction spikes from the top right edge of the image suggest the presence of a large star just out of view.
