Astrometry, what is it good for? Among other things it tells us where the heck we are, and that turns out to be only 25,000 light years away from the monster black hole at the center of the galaxy. Closer to home, the astroquarks discuss the exciting return of samples from an asteroid and the Moon by two robotic explorers, plus astronomy trivia and more space news from the venerable Voyager probes.
Maybe it's been a long day, the car breaking down, the kids complaining, fires to put out at work. Now it's your time, time for a moment of calm, and a clear, cool glass of Galactic Gin. Its clean, neat taste will transport you away from earthly troubles for a virtual walkabout the galaxy. You know what you want when your day is oh-ver. Gin, Galactic. Galactic Gin, breakfast of champions (Wheaties).
