Comet ISON was discovered in September 2012 when it was farther away from the sun than Jupiter and was already being called the "comet of a lifetime." The expectation is high that this comet will be much brighter and more spectacular than any in recent memory, though the jury is still out. This live presentation will highlight why Comet ISON is one of the most talked-about comets, feature the most recent comet images, and explain what comets are and where they come from. Weather permitting, observation of Comet ISON on the levee directly behind LASM will follow the presentation. 7 pm at 100 South River Road. $7.25 for adults; $6.25 children and seniors. lasm.org.
