Overall+Justifications


 * __Nebula:__** Nebula couldn't be inhabited by humans as its a gas planet and does not have oxygen, also humans could not survive without oxygen also there are no traces of water, and these to things are essential to human life, therefore without this life is not possible in a nebula.

There is no chance of habitability on neutron stars because they are too hot for any life to exist on and connot support a stable atmoshpere nor liquid water. The radiation the emit would be to much for life
 * __Neutron Star:__**

Planets are obviously the most suitable system to hold life, one very important point we must consider is the fact that earth is capable of hosting life and earth is infact a planet. This is the number one justification of why planets are suitable for life, for there is extremely strong evidence, if not too good to be classified as evidence that life existes on planets
 * __Planets:__**

There is no evidence of habitability and its unreasonable to think that any life could exist on something which has a solid surface of immense heat and radiation and where liquid water cannot exist.
 * __Protostar:__**


 * __Pulsar:__** Without water or oxygen us as humans cannot live, and as pulsars do not provide these things it is obvious that life cannot be sustained on a pulsar. Also the radiation which is emitted from pulsars would be deadly to humans.

__**Red Giant:**__ With the lack of water or oxygen on a Red Giant that alone is enough to make it uninhabitable, but then there also the major factor of the temperature and from 2500 to 3500 degrees celsius, it is impossible for a human to survive on a Red Giant.


 * __Supernova:__** As a supernova is an explosion, the only possible thing involving a supernova that we can experience is viewing it, besides that visiting or living during the area, on the area or around the area during a supernova is impossible. This rules out any habitability chances.


 * __White Dwarf:__** It would be impossible for humans to inhabit a White Dwarf the first reason would be there is no water or oxygen available. Another reason to explain why a White Dwarf is uninhabitable is because during the the early stages of a its life its surface temperature is about 100,000 °C and after many billions of years a White Dwarf can become as cool as the sun which will be around 5700°C.
