        <title>Asteroid on the Rocks</title>
         <description>Scientists found evidence of water ice and organic material on the asteroid 24 Themis one of the largest Main belt asteroids. Astronomers have long speculated that the components of water, hydrogen and oxygen, were locked within asteroids, but this is their first solid piece of evidence, supporting the idea that they may be responsible for bringing water and organic material to Earth.</description>
