Walkabout the Galaxy
Saturn, Enceladus, hydrothermal energy, dark matter
Astrophysics and Astronomy | Physics
The astroquarks dissect the latest news from Saturn's intriguing moon Enceladus. Molecular hydrogen in its geysers suggest that Enceladus' ocean floor has the same kinds of hydrothermal energy sources that may have powered the origin of life on Earth. Plus, lots of Star Wars nerd news, and from the cosmological realm the first map of dark matter bridges connecting pairs of galaxies.
The Penultimate Jedi
Always coming in second, or second to last? Welcome to my world, or, if you like, come take a walkabout my galaxy. I'm out there, using the force, levitating things, jumping and spinning a lot, using a cool purple light saber to slice up some nasty creatures on the dark side, but all anyone ever wants to talk about is the Last Jedi. But why does he get to decide he's the last Jedi anyway? You know what? I'm the last Jedi. Bam. Or should I say [whooshing sound]. Light saber drop and I'm outta here.
