the Hubble telescope floating over our planet                                         NASA

It's an online Advent calendar of photos (with all the pertinent information attached) from the Hubble telescope! OK, so I know we're already well into December, but I just found it and knew I had to share. Plus, think of it this way: You get the fun of catching up: http://www.theatlantic.com/photo/2015/12/2015-hubble-space-telescope-advent-calendar/418197/
   All of which made me wonder if anyone else out there had a calendar, and sure enough, here's one with 25 days of infographics from The Economist (who else?), but beware that most are far from cheery, as they have to do with issues in the news: http://www.economist.com/content/2015-daily-chart-advent-calendar
    Sometimes, it's nice to just forget about the world and regress to the days of innocence, so for those who might prefer to go old-school and find a simple picture behind each window, there's this: http://www.presentationmagazine.com/online-advent-calendar.php
