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...

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...
the sun's outer atmosphere, called the solarcorona, can actually be seen as a bright circle, with the moon blocking the rest of the sunlight. Like the sun below, the corona consists of a plasma—a gas of charged particles. About 80 years ago,scientists foundthat the temperature...

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...

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...
"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...
