At 2 p.m. CST today, I'll be joining Senior Editor Rich Talcott, Associate Editor Sarah Scoles, and Discover's Editor at Large Corey Powell for a Google Hangout discussion on everything you need to know about Comet ISON (C/2012 S1) before it makes its closest approach to the Sun a week from today.
If you can join us, great! http://bit.ly/ISONhangout
If not, you can watch the event live below or come back later to re-live the excitement of this celestial visitor again and again.
Enjoy!
