It's predicted that this will start happening in about 5 billion years, marked with a sudden outrush of energy known as a "helium flash." As the helium fuses, carbon and oxygen are formed and the temperature of the core rises yet again. Soon after, even heavier elements also begin to ...
First, the core, full of degenerate helium ignites violently in the helium flash, where it is estimated that 6% of the core, itself 40% of the Sun's mass, will be converted into carbon within a matter of minutes through the triple-alpha process. The Sun then shrinks to around 10 times...
In the Sun's core,hydrogen is being fusedto form helium. Theenergy created by this process radiatesup to the visible boundary of the Sun and thenoff into space.It radiates into space in the form ofheat and light. Because the Sun isso massive,it exerts apowerful gravitational pullon everyt...
Stars fuse progressively heavier and heavier elements throughout their lives. From the outset, stars fuse hydrogen to helium, but once stars that will form RSGs exhaust hydrogen, they're unable to counteract the force of gravity. Instead, their helium core begins to collapse at the same time a...
Some 99% of the Sun’s energy is generated through reactions that begin with the fusion of two protons. This “proton-proton chain” proceeds via a number of different routes. The most common route involves the fusion of two helium-3 nuclei, while others feature the temporary production of ...
Deep inside the morning sun, hydrogen is being fused into helium at temperatures of millions of degrees. 氢在高温下转变为氦。 X射线和伽马射线以令人难以置信的强力,从太阳的核心向着表层散射开去。 jw2019 His lethargy is contagious, and soon the whole pride sleep lightly in the first rays of...
In here, pressures and temperatures are so high that hydrogen is fused into helium through a process known as fusion. Hydrogen fusion produces the thermonuclear energy that keeps the sun burning and sends radiation out into the universe. Because fusion happens at the core of the sun, we have ...

(ionized gas), composed from hydrogen and helium. There are two large groups of planets: terrestrial planets - Mercury, Venus, Earth and Mars, they are small in size with a rocky surface and are situated nearer to the Sun; planets giants - Jupiter, Saturn, Uranus and Neptune, large ...
