On June 3rd, NASA’s SWIFT X-ray telescope detected a massive gamma-ray burst, GRB 130603B.

The burst was caused by the collision of two neutron stars 3.9 billion light years from Earth, and lasted only two-tenths of a second. However the infrared glow left behind by the event suggested the formation of a large amount of heavy metals.

It is thought that most of the heavier elements in the universe were produced during supernova explosions. However, gamma-ray bursts are so energetic, they can produce metals such as gold.

The Harvard-Smithsonian Center for Astrophysics has been studying GRB 130603B and believes that it may be evidence that most of the gold in the universe was produced by the collision of neutron stars. Their study is available online.

The Bolshoi Simulation, “the most accurate cosmological simulation of the evolution of the large-scale structure of the universe yet made”.

What is actually being shown above is a visualization of dark matter in a small fraction of the actual simulation. Visit the Bolshoi website at the University of California High-Performance AstroComputing Center for more information and visuals.

Astrophysicists at the University of Zurich, in collaboration with the University of California at Santa Cruz, have released a new simulation showing how the Milky Way formed.

This associated video describes the significance of the simulation: http://youtu.be/GYtBQR2oI4U

This simulation took eight months to calculate on a supercomputer, and would have taken 570 years to calculate on an average personal computer.
