A weak magnetic field likely attracted matter inward, contributing to the formation of the outer planetary bodies, from ...

Astronomers have figured out where a stream of long radio bursts is coming from, and its origin is unprecedented. Rather than ...

Earth’s core could contain helium from the early solar system. The noble gas tucks into gaps in iron crystals under high pressure and temperature.

These results suggest that similar reactions between helium and iron may have occurred within Earth’s core shortly after its formation, trapping much of the primordial helium-3 in the material that ...

Scientists have uncovered surprising evidence that helium, a gas long thought to be chemically inert, may actually bond with ...

The path to removing the plant’s estimated 880 tons of nuclear debris is fraught with technical and human risks ...

Scientists no longer need to rely on theoretical models to study the solar core. Neutrinos, emitting from nuclear fusions, ...

As the nuclear reactor “burns” U-235, the concentration of U-235 decreases while radioactive by-products such as fissile plutonium increase. Eventually, the nuclear chain reaction can no longer be ...

A UK startup has unveiled a new fusion-powered space rocket concept called Sunbird for interplanetary travel to Mars — and beyond.

From 3–7 March 2025, members of the Treaty on the Prohibition of Nuclear Weapons (TPNW) have gathered for their third meeting ...

Scientists now know how to drill deep enough to tap into an energy supply that would power the world for more than 20 million years if we capture just 0.1 percent of it.

Neutrinos generated through solar fusion reactions travel effortlessly through the sun's dense core. Each specific fusion ...
