Plutonium discovered at the bottom of the ocean ... which they can no longer fuse because it is too stable. These stars are so massive (at least 8 solar masses) that gravity causes them to ...

Radioactive materials offer an alternative power source ... RTGs excel at space applications, because these nuclear batteries are highly stable, lightweight and free of moving parts. In 1959, a ...

Stable isotopes do not decay into other elements. In contrast, radioactive isotopes (e.g., 14C) are unstable and will decay into other elements. The less abundant stable isotope(s) of an element have ...

That means that a facility will be built at Sellafield where the plutonium can be converted into a stable, rock-like material ...

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 ...

Stable isotopes are non-radioactive forms of atoms. Although they do not emit radiation, their unique properties enable them to be used in a broad variety of applications, including water and soil ...
