NASA Releases Two Interactive E-books About Hubble, Webb Space Telescopes, Free

From Nasa.gov:

NASA’s Hubble Space Telescope has been providing amazing images of the universe since April 1990 and has led to remarkable discoveries. NASA’s James Webb Space Telescope is the next-generation telescope that will peer even deeper into space and unveil even more mysteries. Both of these extraordinary telescopes are now the topics of two free e-Books available from the Apple iBookstore.
The books are written on a high-school level and can be viewed using iPads with the free iBooks app. Because they’re about two NASA space telescopes, the Hubble and its successor, the Webb, the books complement each other.

The e-books are highly interactive and include image galleries and video. Tracy Vogel of the Space Telescope Science Institute in Baltimore, Md., is part of the design team that put them together. “For instance, the readers can watch a galaxy collision simulation video, manipulate a telescope model to see it from all angles, or flip through a gallery of planetary nebulae—all right there on the page,” Vogel said.
