Six planets will be visible in the sky tonight, forming an astronomical alignment known as a "planetary parade," and you can watch it live online.
Mars, Jupiter, Uranus, Neptune, Saturn and Venus all meet up together on the same side of the sun in a wide arc above Earth — and most are visible to the naked eye under clear night skies. The Virtual Telescope Project in Italy is offering viewers a chance to catch this mesmerizing planetary alignment during a free webcast today (Jan. 25).
