[PAST EVENT] Colloquium - Kunio Sayanagi (Hampton University)
September 18, 2015
4pm - 5pm
Abstract:
NASA's Cassini Orbiter is now in its 11th year of orbiting Saturn. When it arrived at Saturn in 2004, the northern hemisphere was in winter, and the north polar region was shrouded in the winter polar night and was not observable in visible night. Saturn underwent equinox in 2009, and the sun started shining on the north pole for the first time since 1994, revealing many features in the northern high-latitudes such as the north-polar vortex and the famous hexagonal cloud feature that encircles the pole at 75 degree N. I will give an overview of the latest observation results delivered by the Cassini orbiter from Saturn.
