Powering spacecraft with solar energy may not seem like a challenge, given how intense the sun's light can feel on Earth.

Radioactive decay, or nuclear decay, happens when an unstable atomic nucleus spontaneously and randomly emits particles and ...

Do we inhabit a cosmic wasteland teeming with remnants of massive stellar explosions? Recent research proposes that approximately 10 million years ago, Earth and its Moon were bombarded by debris from ...

The second of three planned shipments of high-level radioactive waste has left the Sellafield site in northwest England and ...

Plutonium discovered at the bottom of the ocean was found to be refuse from a kilonova that exploded close to Earth 10 million years ago. Kilonovas occur when binary neutron stars spiral closer and ...

The explosion released elements heavier than iron—like gold and platinum—through a process known as rapid neutron capture ...

The top local leader for the Hanford nuclear site in Eastern Washington has resigned, which follows the resignation of his ...

Researchers at the U.S. Department of Energy’s Princeton Plasma Physics Laboratory are harnessing the power of computers to ...

Lithium-6 is a crucial material for nuclear fusion reactors, but isolating it is challenging – now researchers have found a ...

Radioactive decay, or nuclear decay, happens when an unstable atomic nucleus spontaneously and randomly emits particles and energy to reach a more stable configuration. This process often causes ...
