30th June 1908 – This #InternationalAsteroidDay falls on the 110th anniversary of the Tunguska Impact, which occurred on that day (June 30) in 1908 over Siberia
An intense, heated blast abraded nearly 1,300 square kilometers of forest plagued the trees and stripped off the standing branches (picture).
Seismic activity was registered as far as England, but the explosion left no crater.
A very strange event in a remote location, which attracted the interest of experts in the early 1920s.
Don Yeomans, now retired manager of the Near-Earth Object Office at NASA's Jet Propulsion Laboratory (JPL), said, "It's the only entry of a large meteoroid that we've come across with reports in modern times A century later, some are still debating the cause and coming up with different scenarios that could have caused the explosion, but the commonly agreed theory is that On the morning of June 30, 1908, a large space rock, about 120 feet wide, invaded the atmosphere of Siberia and then exploded in the sky. "
The Chelyabinsk meteor exploded over Russia on February 15, 2013 and injured 1,600 people many remembered to the event of 1908.
Today, the NASA Center for Near-Earth Object Studies at the JPL is discovering and tracking asteroids and comets whose orbits are 30 million miles from Earth to raise awareness in the event of a Tunguska-like situation in the future.
