Our Sun

Show the Sun’s surface impression, recognized because the round off as it appear in ultraviolet light, graceful from the Sun to shape the solar wind.  (Courtesy by SOHO) . SOHO is a project of international cooperation Between ESA and NASA.

Every feature of the outline image ground magnetic structure. The hottest areas appear almost white, while the darker red areas indicate cooler temperatures. The Sun is the nearest star to Earth, is who has made life possible on our planet. It belongs to the classification of spectral class G2 dwarf (intermediate), has a special feature that differentiates it from a multitude of stars that populate our Milky Way Galaxy.

Insecure border in the form of galactic cosmic rays

The detection advise that the defensive border that separate our solar system from the rest of the galaxy lack the bow shock, because confirmed in the current scientific theories and could have implication on how much radiation (in the form of galactic cosmic rays) enters our solar system. For about a quarter of a century, researchers believed that the heliosphere is moving through the interstellar medium at a rate fast enough to form a bow shock. However, IBEX data have shown that the heliosphere actually moves through the local interstellar cloud at 83,685 kilometers per hour, about 11,200 kilometers an hour slower than previously thought. The bow shock would ionize gas or plasma changes abruptly and discontinuously in density in the region of space that is ahead of the heliosphere.

Our solar system is not protected from the rest of the galaxy. Why?

Fresh explanation of the solar system's borders have unwavering that the Sun moves through space at a speed lower than estimated so far, prevent form the bend over shock that evidently marked the border between our solar system and interstellar medium. The discovery suggests that the protective boundary that separates our solar system from the rest of the galaxy that has no bend over shock, which could have implications for how much radiation (in the form of galactic cosmic rays) coming into our solar system.
