Gamma ray burst eruption
Gamma ray burst eruption. Image 5 of 5. Computer artwork of the jet (white) of a gamma ray burst, erupting from a star's surface (across bottom). This is based upon the collapsar theory of GRBs that says GRBs result from the collapse of the core of a massive star. A black hole forms when the core collapses. The spin or magnetic field of the black hole forms jets from material that is being ejected at near the speed of light. The jets are the source of the gamma rays of the GRB, a massive short-lived burst of energy that is 100s of times brighter than an ordinary supernova. For GRB formation, see images R670/148-152. For GRB jets, see images R670/153-154.

Bose-Einstein condensate simulation
Bose-Einstein condensate simulation. Computer simulation of vortices forming within a spinning Bose-Einstein condensate (BEC). A BEC is a state of matter that can arise at very low temperatures. Atoms are trapped using laser beams and magnets, and supercooled almost to absolute zero. At these temperatures, the atoms all have the same quantum energy state, and are indistinguishable. They coalesce, behaving as if they were one single 'super atom.' During the process, two laser beams are rotated rapidly around each other, causing a stirring action that generates vortices in the atom cluster and facilitates the formation of the condensate. This simulation helped to confirm that BEC's are superfluids - a kind of liquid/gas that flows without friction.
