Happy holidays from space; there's a new, free, astronomic e-book in the iTunes store and all you need to check it out is an iDevice and some time. Hubble Space Telescope: Discoveries boasts a collection of picture, video, and animation that lets you stare out into the beautiful void like never before.

From the iTunes description:

Soar through the universe with the Hubble Space Telescope, exploring discoveries from dark energy to colliding galaxies. This highly interactive eBook features video, image galleries and more to reveal the record of scientific breakthroughs behind Hubble's stunning images of the cosmos.


Included in the book are features like a video simulation a galaxy collision and telescope models that can be rotated and viewed from all angles; this isn't just a picture book. It's a big download—almost a gig—but you can pick it up for free at the iTunes store. And if you have an iDevice with a big ol' retina screen, it's probably worth a look.
