Apochromatic X-ray focusing

A team of scientists from the Paul Scherrer Institut, the University of Basel and DESY have demonstrated the first-ever realization of apochromatic X-ray focusing using a tailored combination of a refractive lens and a Fresnel ...

Astronomers puzzled by 'largest' ever cosmic explosion

Astronomers said on Friday they have identified the "largest" cosmic explosion ever observed, a fireball 100 times the size of our Solar System that suddenly began blazing in the distant universe more than three years ago.

X-ray beams help researchers learn new tricks from old metals

A research team led by the U.S. Department of Energy's (DOE) Argonne National Laboratory used powerful X-ray beams to unlock a new understanding of materials important to the production and use of hydrogen. The goal is to ...

Neutron star's X-rays reveal 'photon metamorphosis'

A "beautiful effect" predicted by quantum electrodynamics (QED) can explain the puzzling first observations of polarized X-rays emitted by a magnetar—a neutron star featuring a powerful magnetic field, according to a Cornell ...
