Today is Asteroid Day. From the website:
Asteroid Day as observed annually on 30 June is the United Nations sanctioned day of public awareness of the risks of asteroid impacts. Our mission is to educate the public about the risks and opportunities of asteroids year-round by hosting events, providing educational resources and regular communications to our global audience on multiple digital platforms.
I didn't know about this until today. Seems like a potential opportunity for more general communication on global catastrophic risks.
