"The last time that all five visible planets (Mercury, Venus, Mars, Jupiter and Saturn) appeared in the same sky together was over 10 years ago, from December 15, 2004, to January 15, 2005. The next presentation will again happen for a period of about one month, starting soon!
All five planets should be visible simultaneously before dawn beginning around January 20, 2016. And they’ll remain visible before dawn from about January 20 to February 20, 2016."
