Long-held secrets continue to be unlocked from href="http://www.universetoday.com/guide-to-space/the-moon/" class="alinks_links" title="" rel="external">the Moon. Researchers taking a new look at a rock brought back by the href="http://www.universetoday.com/guide-to-space/missions/apollo-17/" class="alinks_links" title="" rel="external">Apollo 17 mission have discovered graphite in the form of tiny whiskers within the lunar sample.

Andrew Steele, who led a team from the Carnegie Institution's Geophysical Laboratory said the graphite could have come from carbonaceous impactors that struck both the href="http://www.universetoday.com/guide-to-space/the-solar-system/moon/" class="alinks_links" title="" rel="external">Moon and href="http://www.universetoday.com/guide-to-space/earth/" class="alinks_links" title="" rel="external">Earth during the Late Heavy Bombardment, approximately 4.1 to 3.8 billion years ago, and if so, could provide a new and important source of information about this period in the href="http://www.universetoday.com/guide-to-space/the-sun/solar/" class="alinks_links" title="" rel="external">solar system's early history.

"We were really surprised at the discovery of graphite and graphite whiskers," Steele said. "We were not expecting to see anything like this."/> (...)
