Some cool photo lights images:

The sun breaks through the clouds in the Troodos mountains (cyprus) after a short spell of rain.
in the background you can see a golden area on the sea.

A star is a self-luminous gas ball rich in mass in the astronomy. It is held together by her own gravitation and is hot in the surface from 3,000 to 20,000 degrees. The fact that almost everybody to the bare eye appears point-shaped heavenly body far away stars are, is one of the most important knowledge of the modern astronomy.
Most stars aren't single, but predominantly part of a double star system or multiple system. Some form bigger star clusters or have a planet system. Stars seem in the most different dimensions, brightness and colours and, hence, are classed after certain qualities. You are extremely active gas giants who are hot inside millions degrees and very tumultuous. From her glowing surface they send beside intensive radiation also loaded plasma particles far back in the space and form an astrosphere. Stars and her qualities are also with the question of great importance whether a planet circling them can carry life or not.
Most stars exist of hot plasma. Your radiation energy is generated in the star inside by the set ares core coalescence and reaches by intensive radiation and convection to the surface. But also the compact final stages of the star development like white dwarfs and neutron stars are counted to the stars, although they deliver radiation only on account of her rest warmth.
The best known star next to us is the sun.
Stars have played an important role in all cultures and have inspired the human image. You were interpreted religiously and used to the calendar regulation, later also than navigation stars. In the antiquity the natural philosophers imagined that the fixed stars could exist of glowing rock because normal coal fire didn't seem to be sufficient for the heat working on so big distance. The fact that stars exist, however, only of gas, it was recognised only about 300 years ago – among the rest, by different ones
Interpretations of the solar spots – and by the spectral analysis arising in the 19th century confirms. The first ones physically to sound hypotheses to the education of stars come from Kant and Laplace. Both went out from a clock fog, however, her postulated educational processes differed. Nevertheless, often both theories are summarised as a Kant's Laplace theory.
