If an asteroid were spotted headed towards Earth, what could humanity do about it?
On 30 June, world renowned scientists, Nobel laureates, astronauts, technologists and artists join forces for Asteroid Day (http://www.asteroidday.org/), a global awareness movement to spread knowledge about asteroids and ways to protect Earth from such threats. The Day is held on the anniversary of the 1908 Siberian Tunguska event, the largest asteroid to impact our planet in recent history.
