How Sun Burns Without Oxygen: The mystery of our nearest star

Introduction

The sun is the closest star to earth, and it can be a little overwhelming when you realize how much it regulates our climate, power grids, and communications infrastructure. The sun is also an active star that produces massive eruptions on its surface called solar flares and coronal mass ejections (CMEs). These events send charged particles shooting into space at high speeds that can disrupt electronics on earth or even harm astronauts in space. But how does this happen?

The sun is the densest object in the solar system.

The sun is the densest object in our solar system, but it's not all that dense. After all, it's made of hydrogen and helium atoms—that is a lot of mass! Estimates vary from 500 million to 1 billion times more than Earth's atmosphere (or about 0.1% of its mass). The sun also has an astonishingly high surface temperature of about 6000 degrees Celsius (11 000 degrees Fahrenheit)—much hotter than any other star we know about.

The Sun does have some gravitational pull on other planets because they orbit around this massive ball of gas and fire; however, those forces aren't enough to keep them from escaping their orbits into space: Whatever gravity holds them back has been estimated at less than 1 percent of that exerted by Earth itself!

The higher temperatures at the core of the sun allow for more reactions with each reaction releasing energy.

The higher temperatures at the core of the sun allow for more reactions with each reaction releasing energy. As a result, this creates a ball of plasma that is about 15 million degrees Celsius and has an outer layer of 5500-6000 degrees Celsius (C°). And it's not just cool to think about— it's also important: without these layers, our own planet would be unviable due to its inability to sustain life.

The sun is about half way through its lifetime; when it finishes burning out completely and becomes a white dwarf star or black dwarf depending on how much mass you have inside you will no longer exist as we know it today!

Protons cannot fuse together on their own due to the repulsive force of their like charges.

The sun's core is hot, but it's not hot enough to fuse hydrogen into helium. Protons cannot fuse together on their own due to the repulsive force of their like charges. To overcome this repulsive force, they need a really high temperature: around 15 million degrees Celsius (23 million degrees Fahrenheit).

The sun's core is at that temperature because all of its energy comes from nuclear fusion reactions in which two protons join together to form a single nucleus—a process similar to what happens when you put sugar and water into a heated oven and make sugar cookies!

During a solar flare, magnetic reconnection releases an enormous amount of energy that accelerates particles to very high energies.

Magnetic reconnection is a process that occurs when two magnetic fields come into contact. It's what causes solar flares and other types of space weather, but it happens on Earth as well.

When two magnetic fields come together, they can release an enormous amount of energy that accelerates particles to very high energies—the same thing that happens during solar flares!

Magnetic reconnection also plays an important role in the formation of stars like our sun: when their own magnetic field becomes misaligned with their outer layers, they undergo a period called proton cyclotron resonance heating (PCRH) where material from within the star becomes heated up and radiates away into space until all its fuel has been used up by exploding nuclear reactions at its core.

Solar flares and coronal mass ejections can have a large effect on life on earth, disrupting communications infrastructure and bringing down power grids.

Solar flares, coronal mass ejections and geomagnetic storms are a constant threat to life on Earth. They can cause radio communications to be disrupted and can even lead to a power grid failure. In fact, we’re currently at the mercy of a solar storm right now: an energetic CME (coronal mass ejection) is headed our way.

If you’re worried about it affecting your personal electronics or satellite dish, don't worry too much—the chances of this happening are slim-to-none (except if you live in Canada).

There are still many unanswered questions about our nearest star

There are still many unanswered questions about our nearest star. How does the sun work?

What is it made of? How does its magnetic field work? Why is the surface so hot? What causes solar flares, and how do they affect Earth?

The answers to these questions may be complex, but one thing we know for sure is that there are some pretty cool things happening on our solar system’s largest planet: Jupiter. In fact, scientists recently discovered a new type of storm on Jupiter that has never been seen before!

Conclusion

Despite the mystery, we know a lot more about the sun than ever before. We understand its structure, how it generates energy and why it flares up from time to time. That knowledge has allowed us to harness some of its power for use on Earth as well as in space.
