White+Dwarf

=__**White Dwarf**__=

= = = = ==A white dwarf is a very small (compared to other stars), dense, hot stars at the end point in the life/evolution of a star such as the Sun. ==


==White Dwarfs have masses similar to that of the Sun, but the white dwarf is only about the size of Earth, so the densities of White Dwarf's are high - so much so that 1 tonne on a White Dwarf is probably the same volume as a cubic centimetre. So the atoms that make up a white dwarf are the same structure but the electrons and protons making up the atom are packed as closely together as physically possible. ==

==Star's become white dwarfs after they have turned into a Red Giant and losing their outer layers. The White dwarf is the exposed core of the star, now no longer producing energy by nuclear reactions. ==


==White dwarfs gradually cool and fade to being invisable over billions of years. To summarize - White dwarfs are basically the end stage existance of a former star. ==


==From the pressure of the nuclear reactions, the remaining centre interlocks and splits under it's own gravity, and the product of this is a small - but very dense core called a white dwarf. It is believed that a teaspoon of anything on Earth would have the mass of about 3000kg or 3 tonnes in a very dense white dwarf. ==

==Group 1's report to the SETI is that we have throughly investigated all we needed to for the White Dwarf, but we are sorry to inform you, no a White Dwarf is not in general sutiable to host life, let alone human live. There is no water on the star, and the intense temperature will kill all life, it's like a sona that never stops producing heat.So SETI our offical report is that no, a White Dwarf is not a sutiable location for human live by any possible scientific means known to us as of now .==
