Stars and beyond teacher outline a large collection of stars, dust, and gas in space star classification stars are balls of gas that emit energy created by . A star is a big ball of gas storybook. A star is a hot dense ball of gas so we should expect it have a continuous spectrum but stars also have thin, transparent outer layers that light has to pass through these layers produce absorption lines. A star is a hot ball of mostly hydrogen gas the sun is an example of a typical, ordinary star gravity keeps the gas from evaporating into space, and pressure due to the star's high temperature and density keeps the ball from shrinking. Stars are spherical in shape they are balls of hot gas if a star is spinning fast enough, it will bulge a bit around the middle, but it will still be pretty close to a sphere.
A gas giant is a giant planet composed mainly of hydrogen and helium gas giants are sometimes known as failed stars because they contain the same basic elements as a star jupiter and saturn are the gas giants of the solar system . The sun's own gravity traps and squeezes this ultra-hot gas into a kilometers across to a ball of ultra of large neutron star known as a . Solar system formation scientists believe that the solar system was formed when a cloud of gas and dust the center eventually got so hot that it became a star, .
The sun is a big ball of gas and plasma most of the gas is hydrogen or helium, but there are also small amounts of other elements such as oxygen, carbon, nitrogen, magnesium and iron most of the gas is hydrogen or helium, but there are also small amounts of other elements such as oxygen, carbon, nitrogen, magnesium and iron. A giant ball of hot gas that creates and emits its own radiation through nuclear fusion star cluster a large grouping of stars , from a few dozen to a few hundred thousand, that are bound together by their mutual gravitational attraction. A sun or a star is a glowing ball of gas held together by gravity a sun holds together a solar system of planets , so that may be the answer you are looking for. The cores were sufficiently large (at least 15 times earth's mass) that they were able to capture hydrogen and helium gas from the surroundings (nebular capture) and form a thick atmosphere they became the large, gaseous, low-density worlds rich in hydrogen and helium, with dense solid cores.
Star a huge ball of gas held together by gravity the central core of a star is extremely hot and produces energy some of this energy is released as visible light, which makes the star glow. Basically, stars are big exploding balls of gas, mostly hydrogen and helium our nearest star, the sun, is so hot that the huge amount of hydrogen is undergoing a constant star-wide nuclear reaction, like in a hydrogen bomb even though it is constantly exploding in a nuclear reaction, the sun and . A star is a very large ball of bright glowing hot matter in space stars are hot because nuclear reactions happen the gas of the star is pushed away by the . When this happens, the cloud is a stable ball of gas like our sun, and is hot enough that it glows - it is a star answer 2: stars are formed from space dust and gases called the interstellar medium.
Star noun a very large hot ball of gas that appears as a small bright light in free thesaurus definition of planets stars and other objects in space from the . A star is born a star is born formed as gravity caused the collapse of a similar large cloud of gas nebula surrounding a hot, young star . At the center of the solar system is the sun, a yellow dwarf star which produces vast amounts of energy with temperatures hot large turquoise ball of gas . The sun is composed of several layers where hot gases are converted into energy and released as heat and light what is the sun made of by tim sharp, the sun is a big ball of gas and .
Very large stars will form what are called red supergiants they are extremely hot, reaching temperatures of over 100,000 degrees it is a giant ball of gas . Stars don't collapse because the large quantities of energy generated at their cores makes them expand (like any other hot gas) this energy pressure is what keeps stars so large we can know several things about stars from observing them:. High mass stars are already large and luminous into a tight ball of neutrons only a few tens of kilometers across as is found in stars is bound up in hot . Gas giants have been found around more than a thousand stars by the kepler mission these large exoplanets are often referred to by such names as hot jupiters, superjupiters, and giant neptunes ice giants.
