NASA has answered why the sun would glow if there was no oxygen in space

One of the biggest questions when it comes to the Sun is how it will behave; For example, knowing when it’s about to emit hot and fast-moving radiation like the solar wind, which can be directed toward our planet and cause everything from spectacular auroras and solar displays to damage to satellites and power outages.

Why is the sun still ‘on’?

One of the most frequently asked questions is how the sun is “on”. If there was no oxygen in space to create combustion as we know it on Earth.

Combustion occurs on our planet, with a concentration of approximately 20% of the Earth’s atmosphere, when an element such as wood comes into contact with high temperatures, it reacts with oxygen, Releases energy like light and heat and other chemical components depending on the material being burned.

In fact, if the amount of oxygen on Earth increases, we will see fires more often.

It is a celestial body, shining with its own light.

Scientific answer

The sun doesn’t “burn” as we think it does on Earth. Records on fire or burning paper. This was announced by the National Aeronautics and Space Administration known as NASA (abbreviated in English).

The Sun shines because it is a huge ball of gas at its center A process called nuclear fusion takes placeThe company says.

And that’s it The temperature at the core of the Sun reaches 15 million degrees Celsius And the pressure is abnormally high. Due to this, hydrogen atoms combine to form helium.

“Nuclear fusion occurs when one proton collides with another, they stick together… and release energy. This energy heats nearby objects (and other protons, electrons, etc.)”, says NASA.

more time, This heat grows outward from the center (or core) of the star, Eventually leaving the surface, radiation into space becomes the heat and light emitted by the Sun

Likewise, NASA corrects information on the concept that the Sun burns hydrogen.

“People, including scientists, sometimes say that the sun burns hydrogen and makes it glow. But that’s just talk. In fact, hydrogen does not burn, but rather melts into helium. So oxygen is not needed,” he said.He concludes.

What is solar wind?

According to the European Space Agency, the solar wind is a continuous shower of electrically charged particles emitted by the Sun that change its properties such as speed, density and composition depending on the area of ​​the Sun’s surface. Exposed

As the solar wind travels, it interacts with celestial bodies and spacecraft. They can cause auroras on our planet for solar storms that interfere with or damage electrical systems on Earth or in spacecraft.

Despite decades of research, some aspects of the origin of the solar wind remain poorly understood. Well, by the time the wind reaches Earth, most of the detail has disappeared, making it nearly impossible to trace it to specific areas on the Sun’s surface.

According to data collected by the Solar Orbiter, the solar wind was found to exhibit “footprints” given off by its different regions, which would make it easier for physicists to trace the currents to their points of origin on the Sun.
