A large meteoroid exploded over the Bering Sea on December 18, releasing an estimated 173 kilotons of energy, and NASA shared images captured by its Earth-watching Terra satellite showing a view of the massive fireball in action.thanks to its remote location. On Friday,
The image shows the meteor's smoky path over the sea. It looks like a dark smudge across the clouds.
The space agency says the fireball unleashed more than 10 times the energy of the Hiroshima atomic bomb from World War II. That's less powerful than the devastating fireball that impacted Chelyabinsk in Russia in 2013, but it's still the second-largest meteor explosion of the last few decades.

This is why NASA is working onthat could potentially be much more dangerous than the recent meteor.
