The sun is a ball of gas—a special kind of gas to be sure. It is so hot in some regions in the interior that the atoms have come apart completely to form a state of matter known as a plasma—an electrically charged gas. To understand the physical processes that cause stars, like ...
PROBLEM TO BE SOLVED: To cope with an increase in the size of a substrate to be treated by a reduction in a local stress caused by a deflection of the substrate to be treated by a method wherein the forms of the substrate-constraining surfaces on the outer periphery of the substrate ...
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....
A plasma cutter, or plasma cutting machine, uses a plasma stream to transfer energy to a conductive work material. The plasma stream is typically formed by forcing a gas such as nitrogen, oxygen, argon — or even air — through a narrow nozzle. An electric current produced by an external ...
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 dust1,2,3. However, the precise shape and extent of this shell4,5, the impetus and timescale for its formation6,7, an...
Plasma is similar to gas but it is so hot the atoms have become ionized or charged. In the 1950s, an American astronomer named Eugene Parker theorized that the ionized particles in the plasma were being released from the Sun. At the time, this seemed highly unlikely. However, Parker ...
"The Sun's corona, or extended outer layer, is a region of plasma that is heated to over a megakelvin. As a result of thermal collisions, the particles within the inner corona have a range and distribution of speeds described by a Maxwellian distribution. The mean velocity of these partic...
In fusion, two atomic nuclei are combined to create a heavier nucleus, and the process releases energy. The reaction takes place in a state of matter called plasma, which is distinct from liquids, solids or gasses. In the sun, nuclei collide at hot enough temperatures to overcome the electri...
The surface of the sun is electrically active and it is completely covered by the photosphere. The sun's surface rotates uniformly every 27.3 days unlike the plasma layer of the photosphere.
