  • Scientists have discovered that when icebergs cool and dilut the seas, they also raise chlorophyll levels. This may increase the amount of carbon dioxide that is absorbed in the Southern Ocean, and could have global implications for Earth's climate.

  • Cassini has observed strange variations in radio waves controlled by Saturn's rotation. The findings change current assumptions about radio emissions from gas giants. Studying Saturn and its environment is important in determining the types of planets that exist in the Universe and the potential for
