Light's odd way of behaving both like a particle and a wave is nothing new, but a cool new experiment shows that it's not an either/or but a continuum of gradations from wave to particle. The universe has some crazy stuff going on. We use the wave nature to take a look at an odd transient phenomenon at the core of the Milky Way and for Top quark to embarrass Strange quark at trivia.
Orion may have flashy nebula, the Big and Little Dippers may let you find your way if you're lost, but if you want a constellation to put a smile on your face, look no further than Scutum.

So for your next walkabout the galaxy, scoot over to the galaxy Scutum,
