Frank Summers, Space Telescope Science Institute

Stephan’s Quintet is a collection of five galaxies close together in the sky. Although one member is a foreground galaxy, the others are tightly grouped in space and their shapes show evidence of gravitational interactions and collisions. Observations using visible, infrared, and x-ray light reveal detailed structures that help piece together the history of this grouping.

Dr. Summers will discuss this rich scientific story and present a new visualization, from the AstroViz Project of NASA's Universe of Learning, that explores multi-wavelength insights into this complex compact group.
