The Visit of Comet ISON

Comets are relatively small, icy bodies that usually reside in the outer part of the Solar System. Some comets venture into the inner part of the Solar System, where heat from the Sun causes evaporation, producing a visible atmosphere, or coma, and tails of gas and dust. Occasionally, one will become very bright and produce a fantastic display. Comet ISON is one such visitor that will make it's closest approach to the Sun on Nov. 28. In the next of the popular series Astronomy Open Night, Prof. Alan Calder will talk about comets and the upcoming visit of Comet ISON.

Prof. Calder joined the Stony Brook Physics and Astronomy department in 2007 after research appointments at the University of Illinois and the University of Chicago. His research is in numerically modeling astrophysical phenomena, and he has studied core collapse and thermonuclear supernovae, coalescing neutron stars, classical novae, and X-ray bursts.
