This evening I embarked on a little stellar voyage that I'd like to share with you all. Most people with great taste love astronomy and Sencha Touch 2, so why not combine them in a fun evening's web app building?

NASA has been running a small site called APOD (Astronomy Picture Of the Day) for a long time now, as you can probably tell by the awesome web design of that page. Despite its 1998-era styling, this site incorporates some pretty stunning images of the universe and is begging for a mobile app interpretation.

We're not going to go crazy, in fact this whole thing only took about an hour to create, but hopefully it's a useful look at how to put something like this together. In this case, we're just going to write a quick app that pulls down the last 20 pictures and shows them in a carousel with an optional title.

Here's what it looks like live. You'll need a webkit browser (Chrome or Safari) to see this, alternatively load up http://code.edspencer.net/apod on a phone or tablet device:

The full source code for the app is up on github, and we'll go through it bit by bit below.
