Sentences with phrase «through nuclear reactions»

The low abundance indicated that all of the element could have been made in stars that do not explode, through nuclear reactions that don't involve neutrinos.

When protons from GCRs collide with the nitrogen - 14 (seven protons plus seven neutrons in the nucleus) in the air, carbon - 14 is created (in addition to other isotopes such as beryllium - 10) through a nuclear reaction:

A brown dwarf is essentially a failed star, having formed the way stars do through the gravitational collapse of a cloud of gas and dust, but without gaining enough mass to spark the nuclear fusion reactions that make stars shine.

When a neutrino traveling through the earth collides with an atom in a molecule of ice, a little nuclear reaction can occur, producing blue light.

Enriched uranium oxide is formed into rods and water is used both as a coolant, flowing through the reactor core to transfer heat away, and as a moderator, slowing down neutrons released by fission so that they promote further nuclear reactions.

Long before descending into scientific infamy, Hoyle made what should have been a lasting contribution with a 1954 Astrophysical Journal paper laying out a process by which stars heavier than 10 suns would burn hydrogen and helium at their cores into heavier elements through a progressively hotter series of nuclear fusion reactions.

While nuclear energy is regarded as the lesser of the two evils when compared at an emission level to the burning of fossil - fuels, it may trump on the containment of the heat process, which burns in a contained nuclear reactor through an in - ward heat - chemical reaction called fission, but nuclear energy production is a chain from uranium mining to the toxic waste disposal and therefore as an entire process is an equally high risk environmental option.
