The internet is a vast repository of knowledge. Unfortunately, it's so vast that sometime it's hard to find what it is you want to look at. I'll be posting some of my favorite sites, blogs, videos, ect. here just to share the wealth.
Since I started out with a Sagan quote I thought I would go ahead and put this as the first IIRotD. Cosmos is a beautiful series and a stunning soundtrack from the 80's and quite possibly one of the most watched public television programs of all time. It covers...well to put it in the words of Douglas Adams "the life, the universe, and everything".
Like most science shows it has gotten kind of outdated, but many of the episodes have updates that were filmed 10 years later, and some of these even contain outdated information, but if you just wanted straight facts then you should just read a textbook. This series puts information in an easy to understand format, and more importantly discusses how science can influence everyday life. It also is one of the best shows I've seen that has been able to put into perspective the extremes of size, space, and time. It's definitely worth a watch even thirty years later.
