(CNN)While you were living your life on December 18th, 2018, a giant
space rock exploded 16 miles above the Earth's surface, giving off 10
times the energy of the atomic bomb detonated over Hiroshima. No big deal.

The event is properly called a "fireball," NASA's term for
"exceptionally bright meteors that are spectacular enough to to be seen
over a very wide area."

With an impact energy of 173 kilotons, December's fireball was 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 being shared of December's
fireball are actually quite poetic in scale. This atomic, otherworldly
force appears as a simple red blip above the clouds.
But you likely didn't know about it until now, because scientists only
just noticed it. That's because the area where the fireball exploded,
over the Bering Sea, is extremely remote.

NASA's Planetary Defense Officer Lindley Johnson told the BBC such a
powerful meteor event only happens a few times every 100 years. (As a
side note, "Planetary Defense Officer" is probably as close to a
real-life "Avengers" title as you're gonna get.)

CNN has reached out to NASA for additional comment.
