Walkabout the Galaxy
particles; waves; Milky Way
Astrophysics and Astronomy | Physics
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. Just say Scutum three times fast and we dare you not to giggle. While Scutum may rank 84th in size out of 88 constellations, what Scutum lacks in size, Scutum more than makes up for in style. With a huge, red, pulsating variable star, UY Scuti, who's name is almost as cutie as it's girth is impressive, at almost 1000 times the size of the Sun, and also Stephenson 2-18, a star as large as the orbit of Saturn. So for your next walkabout the galaxy, scoot over to the galaxy Scutum,
