Here's a list of some interesting facts about stars. The sun is the closest star to the earth.The sun is about 150 million kilometers away.Our sun,like most other stars,gives off power and light by nuclear fusion(核聚变),which happens exactly where it's the hottest.The sun is about ...
The sun converts hydrogen into helium through nuclear reactions. Through nuclear fusion, the Sun fuses 620 million metric tons of hydrogen and makes 606 million metric tons of helium each second in its core. This is similar to how nuclear reactors produce heat, and consequently, energy. The he...
Here's a list of some interesting facts about stars;some you might already know, and few that are going to be new.The sun is the closest star to the earth. The sun is about 150 million kilometers away. Our sun, like most other stars, gives off power and light by nuclear fusion(核...
We conclude therefore, that ideas about near-future commercial fission breeder reactors are nothing but wishful thinking. We further conclude that, no matter how far into the future we may look, nuclear fusion as an energy source is even less probable than large-scale breeder reactors, for the...
Our sun, like most other stars, gives off power and light by nuclear fusion核聚变)), which happens exactly where it's the hottest. The sun is about 4. 5 billion years old and it will still last six billion years or so. When it runs out of its fuel (燃料), it would develop into...
the pasteurization process by Louis Pasteur, the first hair dryer, the hot air balloon and many other useful things. Now, they are building the first prototype of nuclear fusion reactor in France, called ITER (International Thermo-nuclear Engine Reactor) with the collaboration of 35 other ...
perhaps by a shock wave from a nearby supernova explosion. Clumps begin to form, and they get hotter and hotter as they gain more mass. When the temperature inside such a “young stellar object” reaches 10 million degrees Celsius, a process called “nuclear fusion” ignites, and a star ...
Nuclear energy is really making a comeback because nuclear energy has virtually none greenhouse gases emission and therefore isn’t warming the planet and causing global warming like some other energy sources. The sun uses nuclear fusion of hydrogen atoms into helium atoms. ...
Between 1946 and 1958 the United States detonated 23 nuclear weapons on the tiny, remote ring of islands that make up Bikini Atoll.
Stars produce light and heat thanks to the nuclear reactions that happen in their core where hydrogen gas undergoes a process called nuclear fusion to form helium. This process releases energy in the form of light and heat. A star is born the first time nuclear fusion occurs. Stars vary ...
