Every other Wednesday we present a new video, so join us to see the truth laid bare...
How old is the Sun? This is a question which has fascinated scientists for a long time. Scientists have now established the Sun’s age with the aid of one remarkable fact that the Sun sings. Naked Science visits Big Bear Solar Observatory in California to meet one of the scientists who has been at the forefront of using the Sun’s sounds to determine its age.
The Sun was formed about 4.57 billion years ago from the collapse of part of a giant molecular cloud that consisted mostly of hydrogen and helium and that probably gave birth to many other stars. Roughly halfway through the most stable part of its life, it has not changed dramatically for four billion years, and will remain fairly stable for four billion more. However, after hydrogen fusion in its core has stopped, the Sun will undergo severe changes, both internally and externally.
