From CNN.com:
The mosaic image is made up of 30 separate pictures made by the Chandra X-Ray Observatory, which monitors space through X-rays that filter out the cosmic dust that can obscure images made with optical devices.

X-rays do not filter out cosmic dust. Cosmic dust "filters" out optical light (and other wavelengths). X-rays are simply not or are barely affected by the dust.
