New View of Supernova Remnant W44

The aftershock of a stellar explosion rippling through space is captured in this new view of supernova remnant W44, which combines far-infrared and X-ray data from ESA's Herschel and XMM-Newton space observatories.

Meson Decay Demonstrates Time Flows in Preferred Direction

Bending light around corners is usually done with mirrors, but now scientists have realized self-bending light beams that propagate along curved paths.

Cambridge Scientists at LHC Observe Very Rare Particle Decay

The result is very damaging to new theories like the extremely popular Supersymmetry.

X-ray Laser Pulses Can Strip Electrons from Atoms to Create Ions with Strong Charges

Researchers using the Linac Coherent Light Source (LCLS) at the U.S. Department of Energy's (DOE) SLAC National Accelerator Laboratory have found a way to strip most of the electrons from xenon atoms, creating a "supercharged," strongly positive state at energies previously thought too low.

Quark Gluon Plasma Emits Ultra Short Laser Pulses

Heavy ion collisions at CERN should be able to produce the shortest light pulses ever created. This was demonstrated by computer simulations at the Vienna University of Technology. The pulses are so short that they cannot even be measured by today's technological equipment. Now, a method has been proposed to create the world's most precise stopwatch for the world's shortest light pulses, using a detector which is going to be installed at CERN in 2018.

Quasars Probe Dark Energy

BOSS, the Baryon Oscillation Spectroscopic Survey, is mapping a huge volume of space to measure the role of dark energy in the evolution of the universe. BOSS is the largest program of the third Sloan Digital Sky Survey (SDSS-III) and has just announced the first major result of a new mapping technique, based on the spectra of over 48,000 quasars with redshifts up to 3.5, meaning that light left these active galaxies up to 11.5 billion years in the past.
