Deep inside Earth is a solid metal ball that ... The researchers also looked at core-penetrating shock waves from Soviet ...

British startup Pulsar Fusion has unveiled Sunbird, a space rocket concept designed to meet spacecraft in orbit, attach to ...

In scientific terms, the energy released from the core or the nucleus of an atom ... and pressure and can be carried out on Earth. Nuclear fission is the basis of nuclear reactors and nuclear ...

Current nuclear power plants on Earth use a different process known as nuclear fission. Fission involves splitting, rather than combining, the nuclei of atoms. While fission uses radioactive ...

Nuclear fission does not release the greenhouse gas, carbon dioxide. A controlled nuclear fission reaction releases one million times more energy per kg than a chemical reaction such as burning ...

The work was done by Haruki Takezawa and Kei Hirose at the University of Tokyo and colleagues, who suggest that Earth’s core could host a vast reservoir of primordial helium-3 – reshaping our ...

Its loss from magma suggests that the planet has a deep reservoir of primordial helium, and the new compounds suggest that Earth’s iron-rich core could hold some of that helium. But the team ...

Yet despite improvements in the design of nuclear-fission reactors ... will require emergency core-cooling systems to remove decay heat from the fission process should there be a 'loss of coolant ...

Radioisotope thermoelectric generators do not rely on chemical reactions like the batteries in your phone. Instead, they rely ...

The Earth's internal layers including the mantle, outer core and inner core. New research shows the inner core undergoes structural transformation likely caused by outer core disturbance.

The dream of nuclear ... the core of a star must be created — extremely high temperature and pressure, along with effective confinement to keep the reaction going. The challenge on Earth has ...
