The Local Interstellar Cloud

Explanation: The stars are not alone. In the disk of our Milky Way Galaxy about 10 percent of visible matter is in the form of gas, called the interstellar medium (ISM). The ISM is not uniform, and shows patchiness even near our Sun. It can be quite difficult to detect the local ISM because it is so tenuous and emits so little light. This mostly hydrogen gas, however, absorbs some very specific colors that can be detected in the light of the nearest stars. A working map of the local ISM within 10 light-years based on recent observations is shown above. These observations show that our Sun is moving through a Local Interstellar Cloud as this cloud flows outwards from the Scorpius-Centaurus Association star forming region. Our Sun may exit the Local Interstellar Cloud during the next 10,000 years. Much remains unknown about the local ISM, including details of its distribution, its origin, and how it affects the Sun and the Earth.
Science, 4 March 2005, by Lallement et al.
the Heliosphere is highly sensitive to the density of interstellar gas, and it could fail almost completely if the Sun passed though a dense cloud of gas, exposing the Earth to massive amounts of harmful radiation. There is some evidence to suggest that the Earth has experienced mass extinctions caused by interstellar explosions in the past - perhaps caused because we were in a dense cloud when the effects of a supernova passed us by.
The gravitation field of the Galactic Plane can cause solar-like winds to behave like steering currents on comets and other objects . The Earth has been pounded in the past, The very sparse, hot gas of the Local Bubble is the result of supernovae that exploded within the past two to four million years Thirty-four thousand years ago (34,000), the second part of a supernova explosion, the shock wave portion, hit the earth. The first shock wave comparatively did not disturb the Earth– It was rather unnoticed. Nothing happened, such that the inhabitants of the Earth would have become alarmed. Nothing heavy plummeted to the planet. They may have noticed a large array of ‘shooting' stars coming into the high, rarefied air. This cosmic castoff from the supernova with cosmic substances in the cosmos were pushed onto Earth. Evidence of remains of dust left behind from event was picked up 1992 by Eleusis space craft interstellar origin Micro meteorites coming from outside solar system They were caused by ions and small particles, all heavily laced with near to microscopic iron. Signs of evidence inside ice sheets over 35 thousand to 72 thousand years old Zodiacal belt shows Evidence of remains of dust left behind from event These toxic radioactive particles would later cause havoc. Man, animals, and plants suffered with radiation sickness. Mutations occurred. Tests of archeological finds show that man then had one blood type: O, some 100,000 to 40,000 years hence. After the supernova influence, humans started showing up with blood types A and B; and O continue to express itself also. Blood types A or B did not exist thousands of years ago. According to some scientists, if we possess those blood types, we are "blood brothers/sisters" to a supernova in the not too distant past. It Would be FOOLISH to not way the possibility that in 2012 we may be entering into a Dense region of Gas...As we align with the Center of Our Galaxy Our SUN Sol has and is being bombarded by particles now coming through the Heliosphere the sun has Gotten Brighter from these particles and has changed from A yellowish hue to a more white because of the increase in particles... We may be on te edge of a Dense Cloud of Gas ..and soon to be entering in 2012 the Densest parts of the LOCAL FLUFF held by the gravity of the black hole of the Milky Way galaxy...
