the sun will enter the red giant phase. During this phase, it switches from burning hydrogen in the core to burning hydrogen around the core, which has been converted to helium by burning hydrogen.

The trailblazing Harvard scientist, who documented the dominance of hydrogen and helium in stars, is still inspiring ...

Evans found that the 4686 series and the Pickering series can be obtained in a helium spectrum showing no trace of the ordinary hydrogen lines. These series were observed a few years ago by Prof.

New observations have revealed early signs of UV light illuminating the cosmos more than 13 billion years ago.

In a star like the Sun, four atoms of hydrogen eventually combine via fusion to make a heavier nucleus of helium. What makes fusion inside a star so useful is that the transformation of a light ...
