Join planetary astronomers and Host Tony Darnell at 4 p.m. EST July 17 for a Google Hangout discussion of Comet ISON, its origins and destination, and why everyone's so excited about it. You can ask your own questions of the experts on hand, and they'll do their best to answer.
The approach of this comet has generated a lot of excitement, it is going to pass extremely close to the sun and when it does, astronomers tell us this may be among the brightest comets we've ever seen hanging in our night sky.
Or will it be a dud?
Well, we're going to talk about that and a whole lot more:
Is it going to hit us?
Where did it come from?
How big is it?
What's it made of?
What's so great about comets anyway?
What if it breaks up? Will the pieces hit us?
How can I get a comet named after me?
Is Scott's head a comet nucleus?
Please join Tony Darnell, Alberto Conti and Scott Lewis as they discuss these and any other questions you can think to ask to some of the planetary scientists working at the Space Telescope Science Institute.
We'll have Max Mutchler , Dr. Bonnie Meinke and Dr. Jian-Yang Li on hand to tell us what Hubble is expected to see, how it will see it and we'll also go into the topic of comets in general.
Zolt Levay will also discuss recent Hubble images of ISON.
