I stumbled across Journey by Starlight via an AdSense ad on this blog. This is one of the best implemented science blogs I have seen, beyond straight science news type content.

No way to contact the author, Albert 2.0, who seems to be based in Dublin, so if you read this, kudos, and leave me a comment!
