New Data About Formation Sun and its Inner Planets

NASA ‘s researchers analyzing samples returned by NASA’s 2004 Genesis mission have discovered that our sun and its inner planets may have formed differently than previously thought.This data revealed differences between the sun and 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. According Kevin McKeegan, a Genesis co-investigator from UCLA, they found that Earth, the moon, as well as Martian and other meteorites which are samples of asteroids have a lower concentration of the O-16 than the sun.

Bernard Marty, a Genesis co-investigator from Centre de Recherches Pétrographiques et Géochimiques and the lead author of the other new Science paper, finds that all solar system objects including the terrestrial planets, meteorites and comets are anomalous compared to the initial composition of the nebula from which the solar system formed and understanding the cause of such a heterogeneity will impact our view on the formation of the solar system.
