Questions about Transit of Venus? Join Live Web Chat with NASA Scientist

Curious about ? Have questions? 

NASA is hosting a live web chat with planetary and solar scientists, during which you can ask questions and learn more about this astronomical event.

From 9 to 11 p.m., Dr. Melissa McGrath will take questions as the transit peaks and begins to wane.

Some of the questions asked so far include:

• How cold does Venus get? 
• Will we be able to see Mercury's transit?
• Are we learning new things on the fly during this Venus Transit or will we have to wait a while for data to be analyzed?
