Planck Mission Releases Images of Galactic Dust

davecl writes "The Planck satellite has released its first new science images, showing the large scale filamentary structure of cold dust in our own galaxy. This release coincides with the completion of its first survey of the entire sky a couple of weeks ago. There's lots more work to be done, and more observations to be made, before results are ready on the Big Bang, but these images demonstrate Planck's performance and capability. More information is available on the Planck mission blog (which I maintain)."

Size?

When talking about things at the galaxy scale, what is considered dust? Is this actual real "dust" of the size that collects on my shelves, grains of sand sized bits, gravel, or something larger?

Huge waste of money

If they wanted pictures of dust, they could have just photographed under my bed!
