In a star’s core, fusion takes terrific temperature and pressure that is provided by the crushing gravity of the star’s ...

This is the promise of nuclear fusion ... sun and other stars, where extreme temperatures and pressures allow hydrogen isotopes, like deuterium and tritium, to fuse into helium, generating ...

Researchers have found an environmentally safer way to extract the lithium 6 needed to create fuel for nuclear fusion reactors. The new approach doesn’t require toxic mercury, as conventional methods ...

Lithium-6 is a crucial material for nuclear fusion reactors, but isolating it is challenging – now researchers have found a way to do this without using toxic mercury ...

British startup Pulsar Fusion has unveiled Sunbird, a space rocket concept designed to meet spacecraft in orbit, attach to them, and carry them to their destination at breakneck speed using nuclear ...

If fusion energy is a must ... two atoms of the hydrogen isotope deuterium), the strong nuclear force binds together these isotopes into Helium-3 and releases tremendous amounts of energy.

Today, we know that the sun, along with all other stars, is powered by a reaction called nuclear ... hydrogen isotopes — will be used to fuel future fusion power plants. Inside the reactor, deuterium ...

Stars are born from the great reservoirs of cosmic material (mostly hydrogen and helium, the most common ... protons can collide so forcefully that nuclear fusion can occur. Physicists call ...

Here nuclear reactions power the star by releasing energy. Helium is formed from hydrogen in nuclear fusion reactions. It is stable, with balanced forces keeping it the same size all the time.

nuclear fusion means making atoms do something that goes against their very nature, outside of a star’s interior. Fusing helium isotopes can be done on Earth fairly readily these days ...

When they reach the end of their long evolutions, smaller stars—those up to eight times as massive as our own sun—typically become white dwarfs. These ancient stars are incredibly dense.

The dream of nuclear fusion has ... “The sun and the stars are all fusion reactors,” says Dinan. “They are element cookers — cooking hydrogen into helium — and then as they die, they ...
