Outer space, or simply space, is the expanse that exists beyond the Earth and between celestial bodies. Outer space is not completely empty—it is a hard vacuum containing a low density of particles, predominantly a plasma of hydrogen and helium, as well as electromagnetic radiation, magnetic fields, neutrinos, dust, and cosmic rays. The baseline temperature of outer space, as set by the background radiation from the Big Bang, is 2. 7 kelvins (−270. 45 °C; −454. 81 °F). The plasma between galaxies accounts for about half of the baryonic (ordinary) matter in the universe; it has a number density of less than one hydrogen atom per cubic metre and a temperature of millions of kelvins. Local concentrations of matter have condensed into stars and galaxies. Studies indicate that 90% of the mass in most galaxies is in an unknown form, called dark matter, which interacts with other matter through gravitational but not electromagnetic forces. Observations suggest that the majority of the mass-energy in the observable universe is dark energy, a type of vacuum energy that is poorly understood. Intergalactic space takes up most of the volume of the universe, but even galaxies and star systems consist almost entirely of empty space.
It is important to understand that color by number books and e-books are designed for kids, who have particular difficulties with learning and also attentiveness.

Color printing is the reproduction of the written word and images in the form of color impressions, which can either be used for a full page or for partial design. It involves separation of different primary color pigments that can be added or deducted to give an impression of other hidden hues. In order to give rise to a neutral color, the process requires the addition of the primary hues in predetermined quantities. The most common use of this technology is in the industrial sector, especially in the print media, where countless impressions must be made in graphical representation to arrive at a preset format of mass reproduction to be used daily. Eventually, you should think that the finished page of the coloring is a work of a little Picasso and most parents are inclined in looking at that way. The search for these free coloring pages also introduces most of the children into internet as well as technology. They actually pick up many things that most of the people only take for granted.
