NASA has just released two free ebooks about the Hubble Space Telescope and its not-yet-launched successor, with interactive features that let readers watch a galaxy collision or manipulate a telescope model between pages, agency officials say.
The Hubble Space Telescope launched in 1990 and has a mission lifetime through at least 2013. The space-based observatory has supplied some of the most dazzling visible-light images of distant cosmic objects, which are featured in "Hubble Space Telescope: Discoveries."
"These new ebooks from NASA will allow people to discover Hubble and Webb in a whole new way — both the science and the technology behind building them," Amber Straughn, an astrophysicist on the Webb telescope project at NASA's Goddard Space Flight Center in Greenbelt, Md., said in a statement. "They collect all of the amazing resources about these two observatories in an excellent product that I think people will really enjoy."
The ebooks are available at the Apple iBookstore or can be downloaded as a PDF from the Hubble's official website.
