Here you discover math and astronomy have the answers to your questions about this day that appears, then disappears with predictable regularity. So sit back, find out about this rare day - and then celebrate it's unique contribution to your life. Yes - it's really good to question your world!

From the makers of junk food and junk mail...comes...SPACE JUNK! Tens of millions of objects floating in orbit around our planet. How did they get there? Can we clean them up? Do they pose a threat to our astronauts or even here on Earth? Come see what Science Museum of Virginia astronomers and TV's Matt Paxton have to say about Earth's history of hoarding objects for decades!! After the show, weather permitting, we will point telescopes into the vastness of space and see things with our own eyes! LiveSky is on Friday, February 17, at 6 pm at the Science Museum of Virginia. $5 or free for Museum members.
