On Dec. 18, 2018, a large "fireball" — the term used for exceptionally bright meteors that are visible over a wide area — exploded about 16 miles (26 kilometers) above the Bering Sea. The explosion unleashed an estimated 173 kilotons of energy, or more than 10 times the energy of the atomic bomb blast over Hiroshima during World War II. Two NASA instruments aboard the Terra satellite captured images of the remnants of the large meteor. The image sequence shows views from five of nine cameras on the Multi-angle Imaging SpectroRadiometer (MISR) instrument taken a few minutes after the event. The shadow of the meteor's trail through Earth's atmosphere, cast on the cloud tops and elongated by the low sun angle, is to the northwest. Credit: NASA

ursulaclopez Hello! I am a rhythmic gymnast and I am participating in a promotion to win a course. To help just give a like in the last photo posted on my instagram. Thank you!

supageek_designs @Nasagoddard looks like it broke through the clouds and the pic shows waves under the explosion? Am I seeing that correctly?

plane_crazy_tom Glad there wasn't any aircraft in that vicinity at that time. I'm guessing the shockwave would've been devastating.

senselessinspace Very disappointed when i read the comment section. Thanks for the share @nasagoddard

_mbyrne_ @nasagoddard were you able to observe a subsequent shockwave on the clouds below?

arthow Did nasa predict this was going to happen?
