Walkabout the Galaxy
gravitational waves, black holes
Astrophysics and Astronomy | Physics
The astroquarks kick off the new year with a look at a clever and challenging new technique to detect gravitational waves created by supermassive black holes in the center of galaxies, and maybe even by the big bang itself. The waves make the Earth's position change, resulting in apparent changes in positions of things we look! Plus: astronomy predictions for 2018, nerd news, and space trivia.
In this time, when it may seem like everyone is pulling in different directions, syzygies would like to remind you that wonderful things are possible if we are aligned, astronomically, at least. Whether it's a lunar or solar eclipse, a planetary transit, a solar occultation, or even just a super moon, syzygies are what they're all about. Plus it's the word that's the most fun to randomly throw into a conversation. Try..."did everyone catch the amazing syzygy last night?" at your next dinner party and see all the great reactions you'll get. From blank stares, to nervous giggles, rolled eyes, or quick changes of the subject. Syzygies, see how many you can spot on your Walkabout the Galaxy.
