The Dirt on Andromeda
The Dirt on Andromeda
NASA's image library records The Dirt on Andromeda.
This image from NASA Wide-field Infrared Survey Explorer highlights the dust that speckles the Andromeda galaxy spiral arms. The hot dust, which is being heated by newborn stars, traces the spidery arms all the way to the center of the galaxy.
