For the next month, January 20 through February 20, we will be treated to a rare spectacle in the sky. The five planets closest to Earth, will align in the sky.
The October night sky will feature several planets visible in the overnight sky. First catch Saturn, then Jupiter, Mars and Venus, and finally Mercury in the night sky as this month's planetary parade begins.
The Cassini space probe was launched in 1997 with its mission to enter the orbit of Saturn and study the planet's rings. Cassini arrived at its destination in 2004 and has been studying the planet since. This Friday, July 19, at 5:27 p.m. EDT, the space probe will take a picture of Earth from its vantage point 898 million miles away.
