Simulating clouds of gas in space with foam balls and laser beams is helping us figure out how supernovae can stimulate star formation.
NASA, ESA, and the Hubble Heritage -ESA/Hubble Collaboration
when they interact with shock waves from supernovae. In theory, the shock waves stretch and squeeze the gas and create dense areas that can then collapse into stars. This process is difficult to study in detail from afar, though, and it includes complex dynamical effects such as turbulence that are difficult to simulate in computers.
at the École Polytechnique in Paris and his colleagues used a sphere of carbon-hydrogen foam about 1 millimetre across to represent the molecular cloud.They placed the sphere in a chamber with a small carbon pin, then fired a high-energy laser at the pin, rapidly heating it until it exploded. “It’s similar to the explosion of a star, but much smaller,” says Albertazzi.
