How Does The Sun Produce Energy?
There is a reason life that Earth is the only place in the Solar
System where life is known to be able to live and thrive. Granted,
scientists believe that there may be microbial or even aquatic life
forms living beneath the icy surfaces of Europa and Enceladus, or in the methane lakes on Titan. But for the time being, Earth remains the only place that we know of that has all the right conditions for life to exist.
One of the reasons for this is because the Earth lies within our Sun’s Habitable Zone
(aka. “Goldilocks Zone”). This means that it is in right spot (neither
too close nor too far) to receive the Sun’s abundant energy, which
includes the light and heat that is essential for chemical reactions.
But how exactly does our Sun go about producing this energy? What steps
are involved, and how does it get to us here on planet Earth?
The simple answer is that the Sun, like all stars, is able to create
energy because it is essentially a massive fusion reaction. Scientists
believe that this began when a huge cloud of gas and particles (i.e. a
nebula) collapsed under the force of its own gravity – which is known as
Nebula Theory
.
This not only created the big ball of light at the center of our Solar
System, it also triggered a process whereby hydrogen, collected in the
center, began fusing to create solar energy.
Technically known as nuclear fusion, this process releases an
incredible amount of energy in the form of light and heat. But getting
that energy from the center of our Sun all the way out to planet Earth
and beyond involves a couple of crucial steps. In the end, it all comes
down to the Sun’s layers, and the role each of them plays in making sure
that solar energy gets to where it can help create and sustain life.
