Scientists have produced a powder of plutonium-238 for the first time in nearly 30 years in the United States, a milestone that they say sets the country on a path toward powering NASA's deep-space ...

Plutonium-238, which produces heat as it decays, is typically used to power spacecrafts. Recently, scientists from the Department of Energy’s Oak Ridge National Laboratory have successfully ...

Common chemical elements are created in stars like our sun. But heavy elements, like iron, are thought to form in massive stars that explode and spew material — though it might be more complicated.

A team of scientists has discovered a new, stable form of plutonium – and done so by accident. The famously unstable element is tricky to transport, store and dispose of, but the find could lead to ...

Researchers looking at miniscule levels of plutonium pollution in our soils have made a breakthrough which could help inform future 'clean up' operations on land around nuclear power plants, saving ...
