IBEX! Search for the Solar System's Edge

IBEX: THE SEARCH FOR THE EDGE OF THE SOLAR SYSTEM.


The IBEX spacecraft


FULL DOME PROGRAM


Where does the solar system end? What defines the boundary separating the solar system and the interstellar medium? The IBEX (interstellar boundary explorer) craft captures energized neutral particles originating from the heliosphere: the bubble enclosing the solar system.


The IBEX probe uses these particle captures to construct an image of the heliosphere.


 


How does the probe work? Who built it and how?


Join us for this engaging full dome program and learn what lurks at the outer edges of our solar system.


Show duration: 31 minutes


(Each presentation also includes a live night sky tour lasting approximately 10-15 minutes, so the entire presentation is about 45 minutes.)


 


You may also schedule this program for a group showing.
