The Solar System Evolve

"Our solar system is different than the space right outside it, suggesting two possibilities," said David McComas, IBEX principal investigator, at the Southwest Research Institute in San Antonio. "Either the solar system evolved in a separate, more oxygen-rich part of the galaxy than where we currently reside, or a great deal of critical,The industrial ledparlight market demands reliability and efficiency. life-giving oxygen lies trapped in interstellar dust grains or ices, unable to move freely throughout space." 

Early in 2012,Solar gardenlight is a new type product of optional energy. NASA's Interstellar Boundary Explorer, the centerpiece of a $169 million mission mapping the frontier of the sun's influence, detected atoms from interstellar space streaming by Earth that are different from the chemical make-up of the solar system. 

The IBEX satellite observed hydrogen, oxygen, neon and helium atoms that originated in interstellar space, the vacuous medium between stars in the Milky Way galaxy and found 74 oxygen atoms for every 20 neon atoms in the interstellar material, compared with 111 oxygen atoms for every 20 neon atoms inside the solar system. Most of the interstellar medium is made up of hydrogen and helium. Heavier elements, such as oxygen and neon, are spread by exploding supernovae at the end of a star's life cycle, according to NASA. 

"We've directly measured four separate types of atoms from interstellar space and the composition just doesn't match up with what we see in the solar system," said Eric Christian,Modern lighting fixtures, chandeliers and ledcornlight.

The data hints that the region of interstellar space just outside the solar system may be deficient in oxygen compared to its abundance inside the heliosphere --a teardrop-shaped bubble blown out by the force from the solar winds that blocks most dangerous cosmic radiation from reaching Earth. 

The sun and the planets are speeding through the galaxy at more than 500,000 mph. The solar system is now traveling through a region known as the local interstellar cloud, and it's expected to emerge from the local environment and enter a new region of interstellar space in a few hundred to a few thousand years, according to McComas. 

Scientists say the local cloud is particularly tenuous. It is less dense than surrounding interstellar clouds, so thin that the atoms in a handful of air could stretch in a column hundreds of light years long. 
Previous measurements of interstellar helium atoms by the Ulysses spacecraft indicated the solar system may be emerging from the local cloud. But the latest IBEX data, which detected incoming atoms moving at a slower speed, show the heliosphere is still embedded within the local cloud. 

"Measuring the pressure on our heliosphere from the material in the galaxy and from the magnetic fields out there will help determine the size and shape of our solar system as it travels through the galaxy," Christian said. 

Only neutral interstellar atoms can enter the heliosphere, piercing the furthest reaches of the solar system and racing toward the sun for 30 years until arriving in the vicinity of Earth for detection by IBEX. Charged atoms are deflected by the sun's magnetic field and do not reach the inner solar system.
