Look Out Below! Today is Asteroid Day

The first Asteroid Day was June 30, 2015. This year, in a series of events that are streaming live to the public, researchers will discuss the history of asteroid impacts, the current state of research into near-Earth asteroids and the threat they could pose to Earth — plus what humanity can do about such threats. At 7 p.m. EDT (2300 GMT), Slooh Community Observatory will host a 4-hour live webcast, during which experts will discuss asteroid detection, deflection and mining.
