NASA warns a mass-extinction causing asteroid more likely to hit our planet ... trends now
NASA scientists reveal Earth could be at a higher risk of asteroid impact than previously believed.
The stark warning comes from James Garvin, the Goddard Space Flight Center Chief Scientist, who determined four asteroids strong enough to blow off part of the atmosphere hit over one million years.
Such sizable space rocks are predicted to strike only once every 600,000 to 7000,000 years.
Garvin and his team analyzed data from several Earth-observing satellites to examine four impact craters and identified larger rings around the sites, determining previous work had misread their findings.
If the new data is correct, the impacts would equate to an explosion 10 times more powerful than the largest nuclear bomb in history, resulting in a mass extinction.
NASA scientists reveal Earth could be at a higher risk of asteroid impact than previously believed. Experts reanalyzed four impact sites of asteroids that hit over one million years and found not only that they were larger but also more powerful
Garvin presented the findings at the Lunar and Planetary Science Conference last week, saying, 'It would be in the range of serious crap happening.'
The team conducted the study as part of planetary defense research but uncovered more than they could have imagined.
Using new high-resolution imagery of four craters made over the past one million years, Gavin could map them in 3D.
The sites included Pantasma in Nicaragua, Bosumtwi in Ghana, Iturralde in Bolivia and Zhamanshin in Kazakhstan.
