Hey Space Placers!
Here is an excellent video that explains Comet ISON and what is to come as the comet gets closer and closer to the Sun: http://www.skyandtelescope.com/community/skyblog/observingblog/Comet-ISON-video-223911871.html
Amateur astronomers are observing and photographing the comet now and its speed has increased to over 70,000+ miles per hour. Comet ISON's speed will continue to increase as it gets closer to the Sun.
The next big event is October 1 when Comet ISON passes by very close to Mars. Every spacecraft and mission will be looking to the Martian skies to catch a glimpse of ISON.
