We’re counting down the days here until the Scientific American tweet-up at the American Museum of Natural History on Wednesday, January 18, starting at 6 p.m. Full details are on my earlier blog post. We’ll enjoy talks, a tour of the “Beyond Planet Earth” exhibition–and some conversations over cocktails. Attendance is free for followers of @sciam and @amnh, but you have to apply to attend here. Oh, and attendees will get to be in a drawing to win one of five free downloads of the Journey to the Exoplanets app from Scientific American and Farrar, Straus and Giroux.

Here’s a list of all the Scientific American editors and bloggers expected at the event, along with me: Jen Christiansen, Krystal D’Costa, Christine Gorman, Fred Guterl, John Horgan, Robin Lloyd, John Matson, Steve Mirsky, Michael Moyer, Caleb Scharf, Sandra Upson and Philip Yam.

While we’re all waiting for this get-together, we thought you’d enjoy this wonderful video, “The Known Universe by AMNH”–which takes you to the edge of the visible universe and back in just six minutes. Mind blown? Just wait until you see the Beyond Planet Earth Exhibit!
