Celebrate the first interplanetary holiday!
Tonight is Yuri's Night — a holiday celebrating the first human spaceflight. You can throw a Yuri's Night party yourself, or simply join one of the 340 parties that are already scheduled
. Scheduled events range from the ubiquitous "let's drink vodka shots in a Russian restaurant" to more kid-friendly, telescope-centric themes. And this year, you can even virtually join the Mars Curiosity Rover as it throws itself the first Yuri's Night party to be held on another planet
. (Which, frankly, sounds a little lonely and sad, so hopefully people turn up for the virtual side of that shindig.)
