Comet Encounter- Wed., Nov. 20 at 10p on WOSU

In this program, scientists around the world follow a once-in-a-lifetime event, the path of the sun-grazing comet ISON. The comet, somewhere between one and 10 kilometers in diameter, is currently just beyond the orbit of Jupiter. As it races past Earth toward the sun it will likely develop a tail to light up the night skies.  ISON will slingshot around the back of the sun to emerge perhaps brighter than ever.  But there’s jeopardy too, ISON could evaporate completely or the sun’s gravity could tear it apart producing a so-called “string of pearls” ,several small comets arching across the night sky.
