When the sky looked oddly even, astronomers imagined a vast sphere of burst-makers surrounding our galaxy
A friendly tour of a powerful idea: gamma-ray bursts as the final fireworks of neutron-star and black hole pairs
New research suggests that the way light bends around galaxies could reveal if the strength of gravity has shifted over cosmic time
