In this special issue of the Bulletin of the Atomic Scientists, published by SAGE, experts reflect on 2011 and highlight what to look out for in 2012 in the areas of nuclear energy, nuclear weapons, ...

The blast may have been a kilonova — a type of neutron star merger — in the wake of a more traditional supernova.

Scientists have precisely measured two unstable atomic nuclei that play a crucial role in explosive X-ray bursts on neutron stars. The results reveal faster nuclear reactions than previously thought, ...

Scientists are uncovering new clues that a cosmic explosion may have rocked Earth at the end of the last ice age. At major Clovis-era sites, researchers found shocked quartz—evidence of intense heat ...

A nuclear winter is a theoretical concept, but if the climate scenario expected to follow a large-scale nuclear war, in which smoke and soot from firestorms block sunlight, came to fruition, global ...

Scientists have revealed for the first time a jaw-dropping early view of an exploding supernova. Observations with the European Southern Observatory's Very Large Telescope (ESO's VLT) have revealed ...
