Is there fire on the sun?

Answer: The Sun does not "burn", like we think of logs in a fire or paper burning. The Sun glows because it is a very big ball of gas, and a process called nuclear fusion is taking place in its core.

Does fire exist on the sun?

The heat and light spreads out from the centre of the ball of gas toward the edges, and that's what makes the Sun glow. So there is no normal “flame” in the Sun – at least not like the flames we have in a fire here on Earth – because the energy and light and heat is coming from the nuclear reaction.

What is the fire on the sun called?

This is a chemical reaction that we call combustion. The sun is carrying out a much different process called nuclear fusion. Each second the sun converts 700,000,000 tons of the element hydrogen into 695,000,000 tons of the element helium. This releases energy in the form of gamma rays.

Is the sun gas or fire?

The sun is a big ball of hot gas and plasma.

Is the sun plasma or fire?

The Sun is our nearest star. It is, as all stars are, a hot ball of gas made up mostly of Hydrogen. The Sun is so hot that most of the gas is actually plasma, the fourth state of matter.

#AskNASA┃ Is the Sun a ball of fire?

What is inside sun?

The Sun is a huge ball of hydrogen and helium held together by its own gravity. The Sun has several regions. The interior regions include the core, the radiative zone, and the convection zone.

Does the sun is not on fire?

The Sun does not "burn", like we think of logs in a fire or paper burning. The Sun glows because it is a very big ball of gas, and a process called nuclear fusion is taking place in its core.

Is the sun lava?

The sun is made up of a blazing combination of gases. These gases are actually in the form of plasma. Plasma is a state of matter similar to gas, but with most of the particles ionized.

Can fire exist without oxygen?

Air is made-up of about 21% oxygen, 78% nitrogen and less than 1% other gases including carbon dioxide and water vapor. Fire only needs about 16% oxygen to burn. Without oxygen, fires won't burn.

Why is it dark in space?

In space or on the Moon there is no atmosphere to scatter light. The light from the sun travels a straight line without scattering and all the colors stay together. Looking toward the sun we thus see a brilliant white light while looking away we would see only the darkness of empty space.

Does sun have air?

To astronomers, the sun is just another dying star, but to everyone else it's a huge burning ball that gives heat, light, and life. So far so good. But what is it burning? We all know that there is no air in space, and therefore no oxygen to burn.

Is there oxygen on the sun?

There is oxygen and many other elements on the Sun. The "burning" you refer to is fusion, it does not require oxygen.

Is there fire in space?

Fires can't start in space itself because there is no oxygen – or indeed anything else – in a vacuum. Yet inside the confines of spacecraft, and freed from gravity, flames behave in strange and beautiful ways. They burn at cooler temperatures, in unfamiliar shapes and are powered by unusual chemistry.

How long will the sun burn?

But don't worry. It still has about 5,000,000,000—five billion—years to go. When those five billion years are up, the Sun will become a red giant.

How is there fire on the sun without oxygen?

The sun does not run out of oxygen for the simple fact that it does not use oxygen to burn. The burning of the sun is not chemical combustion. It is nuclear fusion.

Is the sun hot or cold?

The surface of the sun stays at an incredibly hot temperature of about 5800 Kelvin all year long. The high temperature of the sun causes it to constantly emit prodigious amounts of thermal radiation in all directions, mostly in the form of infrared waves, visible light, and ultraviolet waves.

Why is Blue fire the hottest?

Blue flames usually appear at a temperature between 2,600º F and 3,000º F. Blue flames have more oxygen and get hotter because gases burn hotter than organic materials, such as wood.

Is it possible for fire to be cold?

A cool flame or invisible flame is a flame having maximal temperature below about 400 °C (752 °F). It is usually produced in a chemical reaction of a certain fuel-air mixture. Contrary to conventional flame, the reaction is not vigorous and releases very little heat, light, and carbon dioxide.

Is there anything fire Cannot burn?

Wherever any substance is put in fire it burns and changes into ash. But asbestos is one such material that does not burn in fire. That is why the fireman wear clothes made from asbestos when they enter the burning house.

Is there gold on the Sun?

Careful analysis of the Sun's spectrum shows that about 6 ten-billionths (0.0000000006) of the mass of the Sun consists of atoms of gold. Doesn't sound like much does it? But, because the Sun is so huge, this is a lot of gold!

What is hotter than the Sun?

And the answer: lightning. According to NASA, lightning is four times hotter than the surface of the sun. The air around a stroke of lightning can peak at 50,000 degrees Fahrenheit, while the surface of the sun is around 11,000 degrees. Meanwhile, magma can reach temperatures near 2,100 degrees.

Is the Sun liquid?

Answer: Well, in fact the hydrogen and helium in the Sun are neither in gas nor liquid form. Due to the extremely high pressures and temperatures found in the Sun hydrogen and helium are in a *plasma* state.

Can astronauts look at the sun?

The shuttle/ISS Extravehicular Mobility Unit (EMU) aka spacesuit incorporates a gold-film plated sun visor to protect the astronaut's vision when looking in the general direction of the sun. It is called the Extravehicular Visor Assembly. and in this picture you can see the visor half raised.

What happens when the sun dies?

Once the sun completely runs out fuel, it will contract into a cold corpse of a star – a white dwarf.
