On December 26, 2015 at 03:38:53 UTC, scientists observed gravitational waves-ripples in the fabric of spacetime-for the second time. The gravitational waves were detected by both of the twin Laser Interferometer Gravitational-Wave Observatory (LIGO) detectors, located in Livingston, Louisiana, and Hanford, Washington, USA. Read more

Extreme light from frozen argon LSU physicists Mette Gaarde, Mengxi Wu, Kenneth Schafer, and Dana Browne, in collaboration with a team of researchers at SLAC/Stanford University have directly compared the ultrafast, extreme ultraviolet radiation emitted by argon atoms when they are in their gas phase or in their weakly bound solid phase and found significant differences between them, as reported today in the journal Nature. The results yield new clues about how energetic electrons in a solid behave, and may yield new compact sources of short wavelength radiation. Read more
