    there is a chain reaction of hydrogen fusion and fission(of helium which is formed after hydrogen fusion) that goes on in the sun.

    BUT ...Where does the radiation created by hydrogen fusion in sun goes?why doesn't it effect the sun?

    what happens to the radiation created during this? why doesn't it effect sun or its surrounding? how can sun with stand such a strong radiation?

    Where do you think sunlight and the heat of the sun comes from...

    The other thing that the radiation and heat from the reactions does is provide pressure to stop the sun from collapsing under its own gravity.

    well i understood the first part. but the second which comprises of gravitation and collapsing is not clear at all. its a project on which i gotta work and im not that good with science.
    so please explain it with details and basic info.sincere request.

    Radiation sounds nasty to us, because we are composed of relatively fragile highly complex structures of molecules that random particles flying around can break, but for the sun, radiation is just noodles in the soup, its part of the mix.

    When radiation is created, it finds itself in the sun soup, smack in the middle of the suns gravity well, the energy causes inside out pressure, like soup boiling in a casserole, but the mass of the sun causes gravity which pulls most of it towards the center (the soup doesnt explode right out of the casserole, just the wee bit thats far from the center and leaks out). The sun is pretty much in a state of equilibrium, but since its on a colossal scale, the wee bit that trickles out from the edges, from our perspective scale means giant flares, massive emissons of light(that take a few minutes to reach us), crazy heat, stupendous solar radiation, the whole nine yards.

    The solar wind/particles projected from the sun, is putting pressure on out earths magnetic field, distorting it a bit, and since its dounut shaped, the energy particles that hit the atmosphere from the upper part of the doughnut hole cause aurora (lights in the night sky nearer to the poles). Another effect on the surroundings is the tail of comets, which are oriented away from the sun even when they travel back away from the sun (in effect when the comet is back on its way towards te outside of the solar syste, the tail is in front of it)

    I'm not asking anyone to do my homework.i always do my work by myself( esp. when its related to science)

    they can give me some basic info. so at least I'll know where to start my project from.
