Years Ago: The Tunguska Asteroid Impact Event
On June 30, , an asteroid plunged into Earth’s atmosphere and exploded in the skies over Siberia.

Because of the remoteness of the site, the event garnered little attention even within Tsarist Russia and much less outside. The first scientific expedition did not reach the area until , but still funnen ample evidence of the asteroid’s destruction caused by the chock wave and heat blast from the aerial explosion. Archaeologists have found evidence of similar events in the past, and smaller asteroids regularly break up in the atmosphere causing little or no damage. NASA established the Planetary Defense Coordination Office and during the DART mission tested the technology to redirect a small asteroid should one pose a danger to Earth in the future.

The Wave (Arizona)
Rock formation in the Vermilion Cliffs National Monument in Arizona, US
