# Tours of the Universe  Anything in WWT can be included in a so-called _Guided Tour_ which looks like a video with narration, music, text, graphics and hyperlinks. [see the link to the "filmstrip" example offered above...] A tour has the distinct advantage over video in that a tour is interactive at ANY time. When paused, the user is in the environment and free to zoom closer into a detail, or switch see what that object looks like in other wavelengths, find more information or branch off on another related tour.   WorldWide Telescope comes with access to dozens of Tours, created by expert astronomers and educators. Tour subjects span a wide range from the very general (e.g. _"Astronomy for Everone"_) to specialized tribute tours highlighting the work of important astronomers (e.g. _"John Huchra's Universe"_ or _"Galileo's New Order."_)   _Galileo's New Order_ was created in honor of the 400th anniversary of Galileo's first telescope, and it uses WWT's 3D "Solar System" environment to re-create Galileo's 1610 observations of Jupiter. WWT is used to show Jupiters moons moving back and forth in almost a straight line on the Sky as time progresses, and scenes within the Tour superimpose Galileo's own drawings (from _Siderius Nuncius_) on top of Sky views for the particular snapshots in time when each of Galileo's observations was made. To explain what Galileo was imagining as the cause for the apparent "back and forth" motions of the moons, the Tour features the moons orbiting viewed in 2D (on the Sky) _and_ in 3D, using modern NASA images taken from orbiters. To create this Tour, Goodman and Wong collaborated with WWTA Program Director Pat Udomprasert (see box [and let's put WWTA in a box, OK?]) and Owen Gingerich, a world-leading expert on Galileo. The Tour's goal is to explain how Galileo's revelation that the "Galilean" moons orbit Jupiter confirmed Copernicus' idea that the Earth went around the Sun, keeping its own Moon in tow. The full Galileo Tour, and dozens of others, can be viewed in interactive form, or as video, at the [WWT Ambassadors website](http://wwtambassadors.org), and also within WWT itself.  diff --git a/layout.md b/layout.md  index 692e14d..e81fbeb 100644  --- a/layout.md  +++ b/layout.md
