Magnetic fields are present in a large variety of stars across the Hertzsprung-Russell diagram, during all evolutionary stages from pre-main sequence stars, to main sequence stars and evolved stars, up to the final stages when the star explodes as a supernova.  Based on a new theoretical model, a team of scientists explored the rich data archive of ESA's XMM-Newton and NASA's Chandra space observatories to find pulsating X-ray emission from three sources.  CfA astronomer David James was a member of a large international team systematically searching for new gravitationally lensed quasars.  For the first time astronomers have detected gravitational waves from a merged, hyper-massive neutron star.  A group of scientists from the Niels Bohr Institute (NBI) at the University of Copenhagen will soon start developing a new line of technical equipment in order to dramatically improve gravitational wave detectors.
