A wave of exploding stars may have provided the conditions required to build the solar system. New research probing a nearby star-forming region examines conditions that may have been similar to those found in the early solar system to try to solve the outstanding mystery of how radioactive elements essential to planet formation arrived in the environment around the sun.
