PROTO+STAR

=**__Protostar__** =

 ==A protostar is one of the first steps of formation in the process of star's. It can be compared to an embryonic cell in it's inital stage of human life. The formation of a protostar occurs when a cloud of gas - the scientific name for the clouds of gas is T Tauri winds, a type of super solar wind in space breaksdown from the intense interior pull of it's own gravity. ==

==This forms a packed ball of gas, which under such pressure starts radiating energy, and as the clouds continue to pull down from the gravity, a rise in temperature occurs and then the conversion of gravitational energy to thermal kinetic energy causes nuclear fusion at the centre of the gas ball, discharging infared radiation which turns this matter into a protostar. ==


==The protostar initally may be surrounded by a disc of gas and dust for a million years or so. But basically to give you an idea; a protostar is an inital initation to the life of a star. ==

==Group 1's report to the SETI is that we have throughly investigated all we needed to for the protostar, but we are sorry to inform you, no a Protostar is not in general sutiable to host life, let alone human live. There is no water on the star, and the intense temperature and radiation will kill all humans. So SETI our offical report is that no, a Protostar is not a sutiable location for human live by any possible scientific means known to us yet. ==  == == ==When Nebula gas and dust join and generally come closer together, they form a protostar. As more material is pushed into the protostar, the centre of the star becomes really hot, so hot that imagination can't fathom it. It becomes so hot that nuclear reactions can blossom in that environment. When these reactions become more and more intense, atoms of hydrogen get fused together, this causes helium and because of the heat - the helium gives out a type of light energy. This then causes a main sequence star, an example of a main sequence star can be our  ==
