Amazing Cosmic Simulations - Astronomy Videos from The New Scientist (VIDEO)
Astronomy Videos from The New Scientist

The New Scientist just released a bunch of amazing scientific simulations courtesy of NASA/Swift/Cruz deWilde of a variety of cosmic events.  The video above shows how astronomers think light from a gamma-ray burst called 080319B was released. A narrow jet punched though the outer layers of a collapsing star, then followed by a wider, less energetic beam.

Enough data has been collected from the Hubble (and other) telescopes and computer simulations are sophisticated enough now to visualize some of the universe’s great mysteries.

Astronomers think they know what caused the brightest ever gamma-ray burst, which was observed in March: a tightly beamed jet of matter that happened to be aimed almost directly at Earth. Gamma-rays bursts are thought to be caused when massive, spinning stars collapse to form black holes and spew out jets of gas at nearly the speed of light. These send gamma rays our way, along with visible light produced where the jet heats up surrounding gas. (space.newscientist)
