In astrophysics, stellar nucleosynthesis is the creation of chemical elements by nuclear fusion reactions within stars. Stellar nucleosynthesis has occurred since the original creation of hydrogen , helium and lithium during the Big Bang .

May 2, 2018 · Elements. Stellar nucleosynthesis. Fusion. People long assumed all the elements we see now were created during the Big Bang. But on May 2, 1952, an astronomer reported spotting new elements coming...
A star is a luminous spheroid of plasma held together by self-gravity. The nearest star to Earth is the Sun. Many other stars are visible to the naked eye at night; their immense distances from Earth make them appear as fixed points of light.
The answer to this fundamental question of astrophysics was discovered in 1925 by Cecilia Payne and explained in her Ph.D. thesis. Payne showed how to decode the complicated spectra of starlight in order to learn the relative amounts of the chemical elements in the stars.
Apr 16, 2024 · Scientists are exploring the concept of creating a star on Earth through controlled nuclear fusion reactions. This involves replicating the conditions found in the core of stars, where hydrogen nuclei fuse to form helium, releasing vast amounts of energy.
