There are still a few more parts to come. The story has ended up being longer than expected because of some of the revisions I've made. As of right now, I think there will be three more updates. =)
The reason I was able to release so regularly was that I had most of it written already; I was in the process of revising it, and that's been going more slowly than I anticipated. In short: I'm working on it. Be patient! =P
No, I don't take those pictures of the sun myself. =P They're taken by a satellite called SOHO (Solar and Heliospheric Observatory) that is orbiting the sun.
