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?
