The researchers analyzed samples brought back by NASA's 2004 Genesis mission, discovered that our sun and the inner planets of the solar system may have formed differently than previously thought.
The data shows the difference between the sun and the planets in oxygen and nitrogen, which are two of the most abundant elements in our solar system. Although the difference is slight, the implications could help determine how our solar system evolved.
"We found that Earth, the moon, and Mars and other meteorites which are samples of asteroids, have a concentration of O-16, which is lower than the sun," said Kevin McKeegan, a Genesis assistant researcher from UCLA, and lead author of one of the two papers published in Science. boeing military aircraft "The implication is that we did not form out of the same solar nebula materials that created the sun - how and why did it happen remains boeing military aircraft to be discovered."
The air on Earth contains three different boeing military aircraft types of oxygen atoms are distinguished by the number of neutrons they contain. Nearly 100 percent of oxygen atoms in the solar system is composed of O-16, but there are also a small number of more exotic boeing military aircraft oxygen isotopes called O-17 and O-18. Researchers studying the oxygen of Genesis samples found that the percentage of O-16 in the sun is slightly higher than on Earth or on other terrestrial planets. Other isotopes percentage boeing military aircraft is slightly lower.
Other papers detailing boeing military aircraft the differences between the sun and planets in the element boeing military aircraft nitrogen. As with oxygen, nitrogen has one isotope, namely N-14, which is almost 100 per cent made up of atoms in the solar system, but there is also a small amount of N-15. Researchers studying the same samples saw that when compared to Earth's boeing military aircraft atmosphere, nitrogen in the sun and Jupiter has slightly more N-14, but 40 percent less N-15. Both the sun and Jupiter seem to have the same nitrogen composition. As with oxygen, Earth and the rest of the inner solar system are very different in terms of nitrogen.
"These findings show that all solar system objects including the terrestrial planets, boeing military aircraft meteorites and comets are anomalous compared to the initial composition of the nebula from which the solar system formed," said Bernard Marty, a Genesis assistant researcher of the Centre de Recherches et Pétrographiques Géochimiques and lead author Other Science paper. "By understanding the causes of heterogeneity will impact our view on the formation of the solar system."
Data obtained from analysis of samples Genesis collected from the solar wind, or material ejected from the outer portion of the sun. This material may be considered as a fossil of our nebula because the dominant scientific evidence suggests boeing military aircraft that the outer layer of our sun has not changed measurably for billions of years.
"The houses of the sun is more than 99 percent of the material currently in our solar system, so it is a good idea to recognize it better," said Chief Investigator Genesis, Don Burnett of the California Institute of Technology, Pasadena, California. "Although it is more challenging than expected, we have answered some important questions, and like all successful missions, it generates is more."
Genesis was launched in August 2000. Aircraft to travel to Earth's L1 Lagrange Point about 1 million miles from Earth, where it remained for 886 days between 2001 and 2004, passively collecting boeing military aircraft solar wind samples.
On 8 September 2004, the spacecraft's sample return capsule, which entered the Earth's atmosphere. Although hard landing due to parachute failure in the Utah Test and Training Distance in Dugway, Utah, the capsule is NASA's first sample return since the final Apollo lunar mission in 1972, and the first material collected exceeded the moon. NASA's Johnson Space Center in Houston treating the sample and support analysis and sample allocation.
Jet Propulsion Laboratory, Pasadena, Calif., manages the Genesis mission for NASA's Science boeing military aircraft Mission Directorate, Washington. The mission of Genesis is part of the Discovery Program managed at NASA's Marshall Space Flight Center in Huntsville, boeing military aircraft Ala. Lockheed Martin
