Red Supergiant Star
A star of 15 solar masses exhausts its hydrogen in about one-thousandth the lifetime of our sun. It proceeds through the red giant phase, but when it reaches the triple-alpha process of nuclear ...

Ernest Rutherford
Ernest Rutherford (1871 - 1937) greatest contribution to physics were his investigations into the scattering of alpha rays and the nature of the inner structure of the atom. He won the Nobel Prize ...

Rutherford Scattering
The scattering of alpha particles by a thin sheet of gold foil. This experiment demonstrated that most particles passed through the foil completely undeflected, while a few were deflected at ...

White Dwarf Star
When the triple-alpha process in a red giant star is complete, those evolving from stars less than 4 solar masses do not have enough energy to ignite the carbon fusion process and so becomme White ...

A world of particles. Deeper Rutherford
Ernest Rutherford probed inside the atom using alpha particles and found the nucleus. Later, James Chadwick worked out the properties of one of the particles in the nucleus. The next step was to work ...
