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.

Our Solar System

Our solar system consists of its major star, the Sun and a set of body is not just about the eight planets now known, that because the August 24, 2006 the International Astronomical Union meet in Prague which was define planet or to be careful as such or the function of the sound "planet" Pluto was leaving because their individuality do not conform to what is intended by the planet, so going to be a planetoid and for that reason, our Solar System now includes nine planets, but eight, this termination is due to the amount of various bodies that have different sizes orbiting like planets around the Sun as asteroids, comets, meteoric bodies, interplanetary dust and gas, which make this set we call the solar system.

What is the Solar System?

The Solar System is a place or classification of planets orbit a common star (the Sun) which in revolve orbits virtually round method around the center of the galaxy. The 99.86% of the mass of the solar system is restricted in the Sun and most of the respite in Jupiter.

How did it?

Near are numerous theories about the configuration of our Solar System, one of which is the nebular theory:

It indicate that the solar system had formed from a nebula (cloud of gas and dust immense) that began to collapse upon itself due to gravitational forces which outnumbered own pressure forces the gases tend to that the nebula expands.

Types of nebulae

Credit to present telescopes and the use of computers, have been able to expand thorough digital photos, using suitable software, can be colored to obtain spectacular images. The most remarkable aspects of the nebulae are their variety of shapes and structures.

Planetary Nebulae

Planetary nebulae be similar to planets while viewed during a telescope.

Nebulae

The nebulae is more or less solid, evident or not from Earth. Nebulae can be found anywhere in the interstellar space. Before the invention of the telescope, the term nebula was applied to all celestial objects of diffuse appearance. As a result, many objects are now known to be star clusters of galaxies were called nebulae. Nebulae have been detected in almost all galaxies, including our own, the Milky Way. Depending on the age of stars associated, it can be classified into two groups: 1. - Associated evolved stars, such as planetary nebulae and supernova remnants. 2. - Associated with very young stars, some even still in the process of training, such as Herbig-Haro objects and molecular clouds.

Star clusters

Star cluster is a group of stars detained jointly since regards the result of gravitation. Star clusters are classified into two groups: open clusters, which have no definite shape, and globular clusters, which are spherical or nearly spherical. The open consist of a few hundred young stars, while globular clusters contain more than a thousand times that amount, and are generally very old stars. Globular clusters form a halo around our galaxy, the Milky Way, while the open is located in the spiral arms. Open clusters are much more numerous than globular: about 1,000 are known in our galaxy and there are only 140 globular.
