Caption

The researchers simulated supernova conditions by sending a rocket into sub-orbit where it was mostly free from the effect of gravity. The S-520-28 rocket was launched from JAXA's Uchinoura Space Center on Dec. 17, 2012. In the three years to follow, the researchers conducted additional micro-gravity experiments using aircraft to gather and analyze data.
