Water was present just a couple hundred million years after the Big Bang, according to a new study, shaking up the timeline ...

China has set a new milestone in nuclear fusion research with its Experimental Advanced Superconducting Tokamak (EAST), ...

“Before the first stars exploded, there was no water in the Universe because there was no oxygen. Only very simple nuclei ...

For the first time, scientists have captured how complex molecules change shape when exposed to UV light—an ultra-fast ...

“Before the first stars exploded, there was no water in the Universe because there was no oxygen,” said Daniel Whalen, a ...

But solar power is just fusion power that’s happening far away. Slam hydrogen nuclei together into helium and a bit of the original mass is converted into energy. In the core of the ...

Fusion. The new-style “fusion” of hydrogen and the old-style “fission” of uranium have a family resemblance. Both depend on the odd and unexplained fact that atomic nuclei do not weigh as ...

During the majority of a star’s lifetime, hydrogen nuclei fuse together to form helium nuclei. As the star runs out of hydrogen, other fusion reactions take place forming the nuclei of other ...

As the mass falls together it gets hot. A star is formed when it is hot enough for the hydrogen nuclei to fuse together to make helium. The fusion process releases energy, which keeps the core of ...
