Last week, the LIGO Consortium announced the detection of gravitational waves from the merger of a pair of black holes an estimated 400 megaparsecs away. The mc² energy of the gravitational waves was 3 times the sun's mass, converted entirely to energy.
The Hanford, WA and Livingston, Advanced Laser Interferometer Gravitational-Wave Observatories ( Advanced LIGO ) use their own customized "GPL Linux" kernel. Not all F/OSS, they use MATLAB Simulink for some of the data analysis, but all of it was constructed with F/OSS tools on Linux systems. Another win for the penguin and the gnu! They spent 5 months ruling out other local massive events, like deep seismic movements or Bill Gates using an ATM. The announcement paper in Physical Review Letters had 1140 authors from 133 institutions worldwide. Surprisingly readable, and Creative Commons 3.0 .
