The ultimate battle of fire and ice! Who will win, the sun or Comet #ISON?
Join #NASA as we follow the journey of Comet ISON as it slingshots around the sun.
Will the awesome gravity and energy of the sun break up this cosmic ball of ice and rock? Will it break up? Or will it pass the sun intact to put on a dazzling show in the December sky?
Watch as NASA solar physicists track the comet LIVE from the mission control for NASA’s Solar Dynamics Observatory,@NASA_SDO, during #ISON’s closest approach to the sun.
We'll also be joined by comet scientists joining from Kitt Peak Observatory in Arizona, where the solar telescope will be observing ISON and by science writer Phil Plait.
NASA scientists will answer your questions LIVE on air here on Google+, in the YouTube comments section during the live broadcast, or via Twitter using #ISON and #askNASA.
