The largest asteroid in recent history fell on this day, June 30, over 100 years ago. Known today as the Tunguska impact, the 1908 asteroid landed in remote Siberia and accounted for no known deaths or injuries, but it was big enough that scientists today are worrying about what might be next.
To raise awareness about asteroids, how to better detect them and how to avoid possible natural disasters, dozens of notable astronauts, astronomers, agencies and other experts have teamed up for the first-ever Asteroid Day this year.
Here is some of the best reads about the events going on around the world today, the people involved, what you need to know about asteroid detection and what can be done:
