Pluto discovered water ice and blue "sky"

More recently, scientists believed that water in liquid form or in the form of ice in space occurs less frequently. However, the past decade, studies have shown the opposite - in the same solar system is easier to name the objects, where the water in one form or another is not, than to enumerate the planets, satellites and asteroids, where the water is. Now astronomers have found water ice in rather large quantities and on Pluto. In addition, it was found that the haze, which took off at the New Horizons flyby planetoid, blue.
The particles that make up the haze, gray or reddish. But these particles scatter the blue color in a special way, and that has attracted the attention of scientists. This blue color lets us know the size and composition of the particles that make up the haze. Generally blue color appears when dispersed sunlight very small particles. On Earth, the role of such particles are the nitrogen molecule. On Pluto, these particles are larger, but still very small, we call them Tolya .
A theoretical model explains the formation of Tolya dissociation and ionization of molecular nitrogen and methane high-energy particles and solar radiation, the formation of ethylene, ethane, acetylene, hydrogen cyanide, and other small simple molecules and small positive ions, further formation of benzene and other organic molecules, their polymerization and formation aerosol heavier molecules which are condensed and brought to the planetary surface.
Tolya, formed at low pressure, tend to contain nitrogen atoms in the inner part of the molecule, whereas for Tolya, formed under high pressure is more likely to locate the nitrogen atoms on terminals of a molecule. There is an assumption that the development of life on Earth in the early stages, may have influenced the comet with a high content of Tolya, zanёsshie raw material necessary for the development of life.
As mentioned above, the second significant discovery is the discovery of water on Pluto. Clearly, in the form of water ice. Water was found with data from an instrument Ralph.

Most of the water was in the areas that are in the pictures of Pluto appear reddish or red. Scientists are surprised that water ice is an interesting color. So far, the experts do not however put forward any clear theory to explain this fact.
