Due to nuclear fusion reaction large amount of energy is emitted from the sun and it is the only source for the living organisms on the earth. I learn from my book that light shows wave nature and also particle nature depend on the energy. I am really confused how the light travel in space because there is no medium(vacuum) in space. What is light? Is there is any medium for the transfer of light? Is light is a particle? Is light is a wave? Is light can carry energy?

light is a emission of energy
and if we can see it we termed it as visible light but light has ultraviolet as well as infrared region
so these region of light are not visible to us
light is not medium specific
it even travels through air water as well as vaccum
it has wave as well as particle nature
it has electric field and magnetic field perpendicular to each other
it can be transformed into electrical energy using solar cell

In the vaccum what type of nature that the light follow, particle or wave nature?

in vaccum it is the wave nature which drives the light as particles dont exist in vaccum

What is the partice nature of the light, Is light have any weight?

Particle-wave dualism is one of the popular antinomies of science. Antinomies are seeming contradictions between two equally valid principles or from inferences derived from these principles. That light is a particle can be proven scientifically the same way with light being wave but waves are not particles but forms of energy. Yes, light travels in space and there is a precise formula, discussion of which is outside the scope of this limited space.
Interesting topic.
