  • This Universe Today report on the mysterious collision producing the strange stellar object CK Vulpeculae does a great job of outlining a galactic mystery.
  • This report about a proposal by scientists at MIT to create a laser beacon that would signal our existence to extraterrestrial civilizations looking at our sun intrigues, and alarms, me.
  • James Nicoll at Tor notes speculation that strange extrasolar object ‘Oumuamua might be an errant alien artifact. What would that indicate about the galaxy?
