A meteor explodes in the Earth's atmosphere with 10 times the energy of the Hiroshima atomic bomb



The event is properly called "fireball," NASA's term for "exceptionally bright meteors that are spectacular enough to be seen over a very wide area."
With an impact energy of 4.2 kiloton, December's fireball is the second-most powerful to enter Earth's atmosphere in 30 years. You may recall the first – it was that huge, blinding fireball that rocked parts of Russia in 2013.

This may sound catastrophic, but images are shared by December's fireball are actually quite poetic in scale. This atomic, otherworldly force appears as a simple red blip above the clouds.

But you probably did not know about it until now, because scientists only just noticed it. That's because the area where the fireball explodes, over the Bering Sea, is extremely remote.

NASA's Planetary Defense Officer Lindley Johnson told the BBC how to find a powerful meteor event only a few times every 1
00 years. (As a side note, "Planetary Defense Officer" is close to a real-life "Avengers" title as you're gonna get.)

CNN has reached out to NASA for additional comment.

NASA keeps track of most of the notable fireballs and bolides

NASA keeps track of the flaming extraterrestrial objects that are pelting our fragile planet term). So far in 2019, there have been five notable fireball events. Do not worry, though! Most are super tiny.

And the big one ever comes to make dinosaurs of all, NASA's Planetary Defense Office has our backs.
