  • Mars' red exterior is only skin deep
    NASA's Curiosity rover has discovered that under the surface, Mars is more gray than red. The rover dug 2.5 inches into the planet's surface and retrieved rock powder that "may preserve some indication of what iron was doing in these samples without the effect of some later oxidative process that would've rusted the rocks into this orange color that is sort of typical of Mars," said Joel Hurowitz of NASA's Jet Propulsion Laboratory.

  • Video of Mercury highlights planet's colorful terrain
    NASA used photographs of Mercury taken by the Messenger spacecraft to create a video that reveals a global map and colorful details of the planet. "This view captures both compositional differences and differences in how long materials have been exposed at Mercury's surface. Young crater rays, arrayed radially around fresh impact craters, appear light blue or white," one researcher wrote. Space.com (2/22) LinkedInFacebookTwitterEmail this Story
  • Zircon grains came from ancient continent, scientists say
    Scientists say that grains of zircon found on the island of Mauritius may have come from the crust of an ancient continent beneath the Indian Ocean. They say the grains formed almost 2 billion years ago, but the island is only 65 million years old. "It's hard to imagine how zircons could be there any other way," said Michael Wysession of Washington University in St. Louis, Missouri. New Scientist (2/24) LinkedInFacebookTwitterEmail this Story
  • Dinosaurs' long necks had multiple uses, researchers say
    Scientists say food could have been why sauropods, the largest dinosaurs, grew necks that could reach up to 50 feet. The long necks could have helped reach high leaves or sweep through long swaths of ground vegetation. Apatosauruses used their necks for "combat between males -- fighting over women, of course," said researcher Michael Taylor. LiveScience.com (2/23) LinkedInFacebookTwitterEmail this Story

  • White House speeds release of federally funded research
    Federally funded research will be made available for free to the public within a year under a White House directive.
