Walkabout the Galaxy
gravitational waves; black holes
Astrophysics and Astronomy | Physics
The astroquarks go to DragonCon in this special edition of Walkabout the Galaxy. We review the latest gravitational wave discovery of the biggest small black hole seen to date and the surprising abundance of liquid water on small bodies in the solar system. Then test your six degrees of Josh Colwell knowledge in a special egotistical trivia challenge.
These magnificent, flying reptiles may seem fearsome, but don't let those tons of airborne furies spouting ten meter long fountains of flame give you the wrong idea. Behind that scaly armor of every dragon beat the massive heart of a, well, a dragon. Just because you can't incinerate a village with a cough, or crush your foe with razor sharp talons, doesn't mean you should take your insecurities out on these gentle giants of the skies. So make friends with a dragon and go on a walkabout the galaxy together. Your dragon pal may come in handy on Pandora, Pern, or wherever your travels take you. Dragons, drivers wanted. (Volkswagen)
