This month, the two biggest planets in our solar system, Saturn and Jupiter, are coming together in the sky in a once-in-a-lifetime way called a Great Conjunction. It can be seen with telescopes, binoculars, and even the naked eye. Join us for a What's New in Aerospace live chat where we answer your questions about this astronomical event, which hasn't occurred for hundreds of years.
