Thesunis a big ball of gas and plasma, but what is the sun made of exactly? Most of the gas — around 92% — is hydrogen, according toNASA. It is converted into energy in the sun's core. The energy moves outward through the interior layers, into the sun's atmosphere, and is rel...
The sun is made ofgas and plasma. Most of the gas — 92% — is hydrogen. If the sun were smaller, it would just be a huge ball of hydrogen akin toJupiter. According to NASA Space Place, the hydrogen in the sun's core is held together by a lot ofgravityresulting in high pressure...
Nearly all visible matter is made of plasma: the sun, gas clouds, stars and galaxies. In nature, we can observe plasma in the form of northern lights , when the air molecules of the Earth's atmosphere, excited by the plasma of the solar winds, glows in green, blue, red, and violet....
Sustained, ongoing fusion reactions like those in our Sun rely on burning plasmas. Plasma, one of the four fundamental states of matter, consists of a gas of ions and free electrons. A burningplasmais one in which most of the plasma heating comes fromfusion reactionsinvolving thermal plasma io...

For decades we have known that the Sun lies within the Local Bubble, a cavity of low-density, high-temperature plasma surrounded by a shell of cold, neutral gas and dust1–3. However, the precise shape and extent of this shell4,5, the impetus and timesca
made in a book out this week, written by Dale Spender, a lecturer at the London University Institute of Education. She argues that disc rimination against girls is so deeply in co educational schools that single sex classes are the only answer.Her case is based on tape recordings of her ...
The most common phase of matter are solids, liquids and gases. The other two are Bose-Einstein condensates (BEC) and plasma. BEC can only be found in extremely cold conditions in a laboratory or a neutron star. Plasma are gases that have electric properties like the gases used in plasma ...
The solar wind is composed of plasma that is released by the Sun. The plasma is made up of very hot ionized particles of hydrogen and helium gas. How does solar wind affect Earth? Solar wind can interact with Earth's magnetic fields and excite the electrons in the gases found in the at...
This is because when a laser heats, for example, steel, it doesn't melt it. Instead, it causes it to turn suddenly into a small cloud of ionized plasma. This plasma acts as a shield against the beam, which wastes its energy simply making the plasma hotter rather than the target. ...
