Best Answer

Nuclear fusion, the source of all the energy so generously radiated by the Sun, does two things: it converts hydrogen into helium (or rather, makes helium nuclei from protons) and it converts mass to energy. ... If the fusion reactions in the core become too weak, a star can and does collapse.

WHAT ZONE IN THE SUN IS WHERE the thermonuclear reaction take place?

Most nuclear fusion happens close to the Sun's center, or core. That's where the temperature and pressure are greatest.

Could there be a fusion reaction in the earths core driving the heat and magnetic field?

No. A fusion event requires a much greater energy density than can exist at the Earth's core.


How does the sun prodace trmendous energy it releases every second?

It produces so much energy because of the nuclear fusion reaction that happens in the Sun's core every second. Nuclear fusion releases tremendous amounts of energy.


Is it possible for fusion reaction to be happening at a planets core?

No. Fusion requires high concentrations of Hydrogen. Planets are made from substantially heavier elements. Additionally, a planet massive enough to begin a fusion reaction literally becomes a star.

What does increased temperature from contraction in the core cause the helium core to do?

This phenomenon happen during the red phase collapse of smaller stars. The contraction in the core of the star causes the helium to go into a runaway fusion reaction that releases an immense amount of energy for a brief time.
