After all the hoopla on Denmark and publishing sensitive cartoons I wanted to promote the Danish National Space Program. They are working on the coatings of optics used in the NuStar space telescope. Description from the website:
The Danish National Space Center plays an important part in the mission by coating, calibrating and testing the optic for NuSTAR. This optic uses X-ray supermirrors which is based on depth graded multilayer structures capable of reflecting X-rays at energies up to 100 keV at reasonable graze angles.
From the NuStar NASA site:
By focusing X-rays at higher energy; up to 80 keV, NuSTAR will answer fundamental questions about the Universe: How are black holes distributed through the cosmos? How were the elements that compose our bodies and the Earth forged in the explosions of massive stars? What powers the most extreme active galaxies? Perhaps most exciting is the opportunity to fill a blank map with wonders we have not yet dreamed of: NuSTAR offers the opportunity to explore our Universe in an entirely new way.
