According to Mr. Cain this is a test:
"Will you download and actually use it? If so, then expect us to release a new edition every year."
I'd personally love that. Go check out the Universe Today website and enjoy a free ebook. If you like it, don't forget to share with your friends, families and local astronomy clubs. Double down and reshare Mr. Cain's post while you are at it.
I would be remiss if I didn't mention the other quality projects Mr. Cain is involved in. Try out Astronomy Cast with Dr. Pamela Gay and Fraser Cain for a week dose of astronomy. The Bad Astronomy, Universe Today forums have moved to CosmoQuest.com and continues to be an active and vibrant community. And of course, CosmoQuest.org is still running high quality, citizen science experiments.
Editor's note - there is no link directly to the book from unpwnd.com. There is a choice of pdf or epub plus Mr. Cain is running this as an experiment. Unpwnd loves the high quality productions of Mr. Cain, Universe Today and Cosmoquest and would like to see him receive as much traffic as possible for future reference.
