When a nearby star goes supernova, scientists will be ready

Earth's observatories hope to detect neutrinos and gravitational waves

supernova simulation

STELLAR SWOON  A simulation of a supernova tracks the turmoil in the center of a dying star in the moments after its core collapses. The collapse creates a shock wave (blue line) that travels outward, blasting the star apart. Red colors represent material hurtling outward, blues represent inward motion. The surfaces of the lumpy shapes have equal entropy, which is related to temperature.
