Walkabout the Galaxy
spin in the universe
Astrophysics and Astronomy | Physics
There is no center of the universe, no top or bottom (except for our astroquarks!), but all sorts of things in the universe have a definite handedness, and this includes fundamental particles, whose left-ness or right-ness is captured in a quantum property called spin. Top astroquark Jim Cooney takes us for a spin around new results looking into why there is a preference for certain directions of spin. Closer to home we look into the spin of the early Sun and how it ties into the early evolution of life and rocks on the Moon! So take the universe for a spin with us, and get a tangential trivia and all your space news on Walkabout the Galaxy.
The Summer Solstice!
It's time to get your stones in a row, or maybe a circle as the case may be, to catch the Sun at its summery extreme. Whether you're dancing around Stonehenge or going on a walkabout down under, the summer solstice lets you know it's all down here for the next six months. Party late tonight, because the days are getting shorter and – once the climatological and thermal inertia of the oceanic-atmospheric system are accounted for – the nights are getting colder. Enjoy your longest day no matter where you are on Earth. The summer solstice: lifts and separates.
