NASA Telescopes Discover Strobe-Like Flashes in a Suspected Binary Protostar

Two of NASA's great observatories, the Spitzer and Hubble space telescopes, have teamed up to uncover a mysterious infant star that behaves like a strobe light.

Improved X-ray microscopy makes fluctuations visible

X-ray microscopy requires radiation of extremely high quality. In order to obtain sharp images instrument and sample must stay absolutely immobile even at the nanometer scale during the recording. Researchers at the Technische Universitaet Muenchen and the Paul Scherrer Institute in Villigen, Switzerland, have now developed a method that relaxes these hard restrictions. Even fluctuations in the material can be visualized. The renowned journal Nature now reports on their results.
