A Supernova Remnant

The thin, red veins of energized gas in this image from the Spitzer Space Telescope are the remains of supernova HBH3. The puffy, white feature in the image is a region of star formation. In this false color image, Infrared wavelengths of 3.6 µm have been mapped to blue, and 4.5 µm to red. The white color of the star-forming region is a combination of both wavelengths. The HBH3 filaments show up only at the longer 4.5 µm wavelength.
