One oddity is the amount of oxygen. There are more free-floating oxygen atoms in the solar system into interstellar space immediately, or in the vast region between the stars.Scientists are unsure why, but they said that perhaps some of the life-supporting element can be hidden in the dust and ice.
“We found this great mystery – the only problem is that outside of our solar system is not like the material inside,” said David McComas of the Southwest Research Institute in San Antonio, Texas.
The discovery came from a NASA spacecraft Interstellar Explorer border, which was launched in 2008 to study the chaotic border, where the solar wind from the sun clashes with cold gases from interstellar space.
The circumference of 200 000 km above the Earth, the probe spot ibex streaming particles in the solar sisteme.Zaschitnye bubble surrounding the planets around the sun and prevent dangerous cosmic rays to penetrate, but the neutral particles can move freely, allowing you to map the distribution of ibex.
The presence of less oxygen outside the solar system should not have anything to do search for planets similar to Earth, the scientists involved in the hunt for exoplanets said.
There’s a lot of oxygen in all the stars in the galaxy and of the material from which stars and planets are formed, Geoff Marcy of the University of California, Berkeley, said in an e-mail.
While the probes at the edge of Capricorn solar system with Earth’s orbit, NASA’s long, double Voyager spacecraft nuclear engines in the fields. Established in 1977, the spacecraft explored the boundaries of our solar system since 2004.
The scientists said that they will be months or even years before Voyager 1 out of solar system and the sensor becomes the first artificial cross into interstellar space.
