Energy radiated per second is given by\nE = e*sigma*A*T^4   where \ne = emissivity; \nsigma = Stefan's constant = 5.67 * 10^-8 W/m^2/K^4\nA = surface area\nT = temperature in kelvin.\nSubstituting the various values,\nE = 249 * 10^-8 Watts.

It starts off with a good amount of hydrogen, which is fused into helium as it turns off the main sequence.  The more massive the star, the heavier the element it can fuse up to.  For more massive stars than the sun, helium can be fused higher up to carbon, oxygen, nitrogen, silicon, (i am forgetting one), and anything relatively close to iron.  Most of the elements made near iron will be radioactive and decay into iron.  At iron, you have to put more energy into fusing the atoms than you get out of the reaction.  At this point, for massive stars you will get a supernova as the star stops fusing in the core.  In the shockwave that occurs, enough energy can be put into the iron to fuse even heavier elements.  A good number of smaller than iron elements are also made in the process of making the above stated elements.

It will go nova and a star 15+ sm's will go supernova (if I remember correctly)

At the sun's deep interior(400,000 miles deep!), heat(20million degrees Fahrenheit) & pressure(4 trillion pounds per square inch) act on  700 million tons of hydrogen, converting it to 695 million tons of helium....per second!!!!!! The excess 5 million tons of hydrogen that isn't turned to helium becomes pure radiant energy according to Einstein's famous equation, E=MCsquared,\nwhere E=energy\nM=mass\nCsquared=(speed of light) times (speed of light)!\n\nYou can understand how much energy is created because the (speed of light)squared= 186, 284miles per second times 5280feet per mile times 186,284miles per second  times 5280feet per mile is a seriously big number. When this number is also multiplied to the large hydrogen mass(5 million tons) converted to energy, the Energy unleashed by the sun is stupifyingly stupendous!!!!!!!   The energy unleashed by the sun is the equivalent (& is the very same type of energy) of  11 billion 1 megaton nuclear(not atomic) weapons exploded per second. You might understand this huge energy amount better if you were to think of a square mile of terrain on the earth exploding 55 nuclear weapons per second.... continually & over every square mile of the entire planet earth!!!!!! Such power is unleashed in the sun but it doesn't hurt us(except when we get sun burns & long term cancers). Great processes work in the sun, in the space & electromagnetic fields around the sun & earth, & in the sun &  earth's atmospheres, not to kill us, but to SUSTAIN life on earth. Wow, wow, wow.............WOW!!!!

There are two possible causes of supernovae:\n\n- A massive star may no longer produce fusion energy from fusing the nuclei of atoms in its core. Gravity wins and the star collapses inward under its own weight.\n\n-A old, white dwarf star that has a close companion from which material falls on it. If its mass becomes larger than about 1.5 solar masses it will undergo a thermonuclear explosion. \n\nIn both cases, the resulting supernova explosion expels an enormous amount of steller material forming a nebula.

Hi, Kenny. You are asking for a lot of information. I have written a book, on the history of nuclear science and will link you to it to read online. This space here is awfully limited.\n\nThe short answer is that nuclear science allows us to generate electrical power out in space even when we are far away from stars like the sun. \n\nThere are two ways we do that:\n\n1. Nuclear reactors - just like the atomic power plants on earth, reactors depend upon the splitting of uranium or plutonium atoms to generate heat and then the heat is used to boil a liquid and turn a turbine. The turbine moves a coil of wire through a magnetic field and gives you electricity.\n\n2. Thermopyles - plutonium due to its alpha radioactive decay gets pretty hot naturally. If you put two dissimilar wires wrapped around each other in a heat source and then the other end of the wires in somewhere cold (like out in space), electrons will flow through them. This is called a thermocouple. If you put lots of those together, you have what is called a thermopyle. This kind of technology is pretty flawless and is used even for things like heart pacemakers.

Neutron stars are the remnants left behind when large stars reach the end of their normal "lifespan" and go supernova.  During the supernova explosion, the core of the star collapses to a very small body just a few kilometers across.\n\nMaxwell's equations for electromagnetism imply that a quantity called magnetic flux is conserved in most processes.  This is measured in units of Gauss per square centimeter.  Gauss is the unit of magnetic field strength.\n\nAs the core of the star collapses, its surface area decreases.  Because of the conservation of magnetic flux, the flux through the surface has to stay constant, so the magnetic field strength has to increase to compensate for the shrinking area.  This is sometimes referred to as "fossilization" of the original star's magnetic field.\n\nThe sun is about 1.4 million kilometers across.  A neutron star with the same mass would be about 50,000 times smaller.  Because surface area varies as the square of the diameter, the surface area would be about 2.5 billion times smaller, so the magnetic field would be 2.5 billion times stronger.\n\n(Note, though, that the sun will never turn into a neutron star because it does not have enough mass.  Only stars above the Chandrasekhar limit of about 1.44 solar masses can become neutron stars.)

It wont ever go supernova . Its to small for that\nWhat will happen though is it will swell up as a red giant .    After swallowing the earth and all the planets  it will eventually shrink to a cold dense white dwarf star.\nBut no need to worry this is a long time in the future.

The sun would go out 8 minutes later, turn into a neutron star and we will be irradiated by lethal radiation.\n\nThe sun is superheated plasma and the sun circulates its plasma.  Gravity pulls it in, which makes it hotter up to the point of fusion.  This energy is so powerful that it can overcome the huge power of gravity and rise to the surface, before it is caught by the sun's gravity.  When the sun gets a "tummy ache" then it shoots out more energetic streams creating solar flares.  Under normal conditions some particles are so energetic that they can escape the sun, this is the solar wind.  It is all driven by the circulating plasma and the fusion reaction.\n\nStop this fusion reaction then all solar flares will collapse, the solar wind will disappear so in 8 minutes earthlings will know something is wrong.\n\nSeconds later the only force on the sun will be gravity and it will collapse upon itself.  The sun is too small to form a black hole so it will collapse to the size of a neutron star and all the light will go out.\n\nThe continued gravitational collapse will break up some particles, most of the subatomic particles won't be strong enough to escape, but x-rays and gamma rays can.  Once the new neutron star reaches a point of equilibrium then the radiation produced will slow down.  Until it reaches that point though the new neutron star will be spewing forth only lethal types of radiation.\n\nAfter a few hours\nAll weather is solar driven, so the winds would die and any clouds would stop.  The temperatures would equalize so those clouds would start to move toward the poles (north for the northern hemisphere, and south for the southern hemisphere).  This wind would be very weak though and once the temperatures are equalized it will die.\n\nThe radiation may not be enough to kill all life on earth, but it will cripple it making it weaker and just decreasing the time for the death spiral.  New mutations will appear and die out.  Most wouldn’t have survived any way and the rest will face conditions that are too hard to live for very long, but they may hang on long enough to see the rest of the animals die.\n\nPlants do have storage cells so they will take time to die.  To them it will seem as if a sudden winter came upon them.  They will shed their leaves and go dormant.  The evergreens will still be trying to get light and expending energy to hold out their leaves so their reserves will drop faster and they will start to die first.\n\nAfter a few days\nWhen the plants go into winter mode they will drop all of their leaves (it takes too much energy to hold them), and all of their fruit and vegetables.\n\nThe cooling will be too fast for animals to adapt so they will suffer the full effects of the never ending weather.\n\nAfter a week\nMeanwhile most animals will go insane soon.  We need light to see; even nocturnal animals magnify the existing light.  Once the sun goes out then the only bodies that will have any light are the gas giants of Jupiter and Saturn, because they are emitting radiation.  At first it will only seem like night to the animals, but they live by circadian rhythms so once those rhythms are disrupted they will start to get restless, irritable and soon they will go insane.\n\nNocturnal hunters will do well at first, but those that hunt by day; like the hawk and the eagle when soon starve.  The restless animals will make them more skittish, and harder to hunt, when they get irritable they will become more dangerous to hunt, and when they go insane they will be extremely hard to hunt, until they exhaust all of their reserves and collapse.  The nocturnal predators will do well now, but the diurnal ones will be starving to death.  As more animals die the scavengers will do well, but vultures need to see so they won’t be around for very long.  Without their competition the insects will thrive.  Most predators will not eat a corpse that they or their fellows didn’t kill, because it could

A Supernova....i guess.

approx. 1600000000Kw hrs of electricity per hour you kept it on\n\nthat would cost a lot of money by the way and you might blow a fuse

So E=MCsquared\n\nTaking the example of the lunar module  Saturn V (as used in Apollo 11), which had a mass of 3,038,500 kg, we can use the eqaution to find out how much energy was needed to launch the module.\n\nE(Energy in joules) = (Mass * C) squared\n\nE = (3,038,500 * 3 to the 100000000th power (C is a constant))sqaured  --> unless you have a great calculator, it's pretty hard to work this out, so I'll keep it in this form. To make this easier to understand tho, I'll now substitute the letter 'E' for this value\n\n\nNow, we need to work out how many calories are in each peice of candy corn. Brach's candy corn has 585 Kj per 26 pieces, so each piece has 22.5Kj. As our 'E' is in joules, we need to convert 22.5Kj into Joules, which is 22500 joules per piece.\n\nTherefore, to know how many pieces of candy corn one needs to eat to consume enough energies to launch a lunar module (in this case, Apollo 11), we simply must work out\n\nE divided by 22500. \n\nIf you have a very very expensive and complex calculator that can work out high powers (and thus have a very very long digit count/display) you can do that, but I don't, so I won't!\n\nlol, take care!

The sun is not massive enough to supernova.  The Sun will however eventually swell into a giant that will consume all the inner planets (when the hydrogen fuel is depleted 5 billion years or so from now) and then shrink into a white dwarf star.

Our sun will not supernova.  It will, over a very long time, expand into a relatively small red giant, which will have a diameter greater than the Earth's orbit.\n\nLong before that the Earth will have become far too hot to live on, but the process will be very, very slow -- it'll take over a billion years -- not a giant explosion.\n\nSorry to disappoint you.  I know, you sound like you were looking forward to it.  Funny how many people answering this question think otherwise.  I guess that's the irony of the internet for you.\n\nSee the link below for all the details:

The answer depends on how big or how much each solar panel produces.  But you definetly need at least 1,200 Watts. You can either try to produce the energy Chemically or Mechanically.  Chemically you need Photo Electric Panels Large enough to produce 1,200 watts.  Mechanically you would use mirrors to focus the suns rays onto a boiler to create steam and then turn a turbine generator.

A. Potential energy = Force * Distance\n     = (50 * 9.8) * 10\n     = 4900 J\nB. Power rating = Energy / time = 4900 / 5 = 980 Watts
