    "For this month’s tutorial we will create a visualization of Gamma Ray Bursts. The tutorial was created for A KICP short course for museum and planetarium staff about the Evolving Universe (http://kicp-courses.uchicago.edu/2014/index.php) held this September. Here we will only visualize the data in WWT. While similar visualizations are possible in other planetarium software packages, the process of creating them is somewhat awkward. The time domain is the next great frontier for astronomy, I encourage software vendors to follow along with the tutorial and think about how they can streamline the process of creating a similar visualization using their software.<br><br>\n",
