Artwork of nuclear fusion reaction

Conceptual image representing the process of nuclear fusion, specifically the creation of helium from hydrogen. Four protons (hydrogen nuclei) are combining on the left, releasing in the process two protons and two neutrons (a helium nucleus). The sum of the masses of the neutron and protons is less than that of the original four protons. The 'missing mass' is converted to energy, which we see in the form of electromagnetic radiation. This is the power behind the Sun's brilliant glow. In practice, the conversion of hydrogen into helium is more complicated than this, and undergoes several stages between the two shown here.

Artwork of proton-proton chain reaction

The proton-proton chain is an important nuclear reaction which occurs inside the core of main-sequence stars such as the Sun. It involves the conversion of hydrogen nuclei (protons, or 1H) into helium nuclei (4He) via several steps. First, two protons come together and stick. One of them is converted into a neutron, and debris is emitted in the form of a positron and a neutrino. The result is deuterium - a nucleus consisting of one proton and one neutron. With the addition of another proton and the subsequent emission of a gamma-ray, a new product is formed - an isotope of helium called helium-3 or tralphium. Finally, two of these helium-3 nuclei collide, and two protons are ejected, to make hydrogen. On average, a typical proton can wait up to a billion years in the nucleus of a star before it collides with another to initiate this whole process.

Yakov Zeldovich, Soviet physicist Featured Print

Yakov Zeldovich, Soviet physicist

Yakov Borisovich Zeldovich (1914-1987), Soviet physicist. Zeldovich joined the Soviet Atomic Project in 1943, working on nuclear weapons until 1963. From the 1950s onwards, he also worked on elementary particles, making several important predictions about meson and muon decay, as well as the behaviour of 'cold' neutrons. From the 1960s, he worked in astrophysics and cosmology, working on the large-scale structure of the universe, black holes, and predicting the Sunyaev-Zeldovich effect concerning the cosmic background radiation. He received numerous awards, including three Orders of Lenin (1949, 1962 and 1974) and the Kurchatov Medal (1977). An asteroid has been named in his honour. Photographed in Russia in 1985.
