    space frontier

    Outer space, or simply space, is the void that exists between celestial bodies, including the Earth.[1] It is not completely empty, but consists of a hard vacuum containing a low density of particles: predominantly a plasma of hydrogen and helium, as well as electromagnetic radiation, magnetic fields, and neutrinos. Observations have now recently proven that it also contains dark matter and dark energy. The baseline temperature, as set by the background radiation left over from the Big Bang, is only 2.7 kelvin (K); in contrast, temperatures in the coronae of stars can reach over a million kelvin. Plasma with an extremely low density (less than one hydrogen atom per cubic meter) and high temperature (millions of kelvin) in the space between galaxies accounts for most of the baryonic (ordinary) matter in outer space; local concentrations have condensed into stars and galaxies. Intergalactic space takes up most of the volume of the Universe, but even galaxies and star systems consist almost entirely of empty space.
