A new visualization create by the B612 groundwork break 26 important explosive outcome recorded from 2001 to 2013 that were not the result of atomic detonations — but rather asteroid hit the Earth . That ’s a surprisal , to say the least .
When we think of recent large asteroid impacts on Earth , only a handful may come to heed . In particular , one is the wood - flattening 1908 Tunguska explosion over Siberia ( which may have been the final result of a comet ) and another is the February 2013 meteor that explode over Chelyabinsk , shatter window with its air travel blast . Both occurred in Russia , the largest country on Earth , and had human witnesses — in the sheath of the latter many witnesses thanks to today ’s ubiquitous dashboard cameras .
While it ’s true that those two observed events took home 105 years apart , there have been many , many more large - musical scale asteroid impacts around the world that citizenry have not witnessed , if only due to their remote location — wallop events that , if they or ones like them ever occurred above a city or populated area , could result in destruction of holding , injuries to masses , or worse . ( And these are only the one we ’ve found out about over the preceding 13 geezerhood . )
A new TV released today by the B612 Foundation indicate a visualization of data point collected by a global nuclear artillery exam internet . It reveals 26 volatile events register from 2001 to 2013 that were not the event of nuclear blowup — these were impact by asteroid , ranging from one to 600 kilotons in energy output . For the traditonally gruesome comparison , the bomb calorimeter used to destruct Hiroshima at the end of World War II was about 15 kiloton ; the Nagasaki bomb was 20 .
afterward this eventide , former NASA astronaut Ed Lu , Tom Jones , and Apollo 8 spaceman Bill Anders will present this video to the public at a live Q&A case at the Museum of Flight in Seattle , Washington . chief operating officer and co - founder of the B612 Foundation , Ed Lu is working to increase consciousness of asteroids and near - Earth objects with the ultimate finish of construction and launchingSentinel , an infrared observatory that will search for and identify as - yet unknown objects with orbits that intersect Earth ’s .
The event , titled “ Saving the Earth by go on Big Asteroids off , ” will be held at 6 p.m. PDT . It is free to the public and the visualization above is now useable online on the B612 Foundation website .
A pressure effect will also be take place at 11:30 a.m. PDT , andwill be pullulate live here .
presently there is no comprehensive dynamical function of our inner solar system of rules showing the place and flight of these asteroid that might threaten Earth . The citizens of Earth are basically flying around the Solar System with eyes closed . asteroid have struck Earth before , and they will again – unless we do something about it . – B612 Foundation

Technical note : While B612 and Ed Lu are presenting a Modern visualisation on April 22 , the data behind it are not only new . Previous surveys on NEA populations have settle within reasonable parameters the number of objects and likelihood of future impacts of varying sizes using data from WISE and ground - free-base observatory — see a serial of slides by Alan Harris of JPL / Caltechhere .
