Complete 3D Simulations of Supernovae

Simulation of the explosion of a 40 solar mass star, 1.7 seconds after collapse. The rendered entropy shows regions heated by the expanding shock wave and/or neutrino heating. The development of turbulent convection and global asymmetry facilitate a successful explosion. (Credit: T. Wang, UC Berkeley)

New Angles on Jet Scattering in the Quark-Gluon Plasma at RHIC and the LHC

An artistic representation of a liquidlike fireball of "quark-gluon plasma" (QGP) created in a collision of two gold ions at the Relativistic Heavy Ion Collider (RHIC). This collision has also produced a correlated spray of particles (a "jet") back-to-back with a photon (wavy purple line). Scientists from RHIC's STAR Collaboration showed that interactions of the jet particles cause the QGP to splash sideways, like the wake behind a power boat, enabling them to measure properties of the plasma.
