When stars die out, they emit gamma-ray bursts. Although scientist can calculate the explosion energy from dying stars, it is difficult to do when the conversion efficiency is low or unknown. Using light polarization, a research group has found a workaround for this, enabling astronomers to calculate the hidden energy of gamma-ray bursts.
