Great pictures of fireball over Bering Sea | earth



<! –

->

A NASA instrument aboard the Terra satellite took pictures of a fireball – or an extremely bright meteor – over the Bering Sea on 18 December 2018. The pictures show the fireball and the path of the meteoroid, which is marked by a dark plume of smoke over thick, white clouds. NASA said the meteor exploded about 26 kilometers above the Bering Sea. The explosion unleashed an estimated 173 kilotons of energy or more than ten times the atomic bomb power of Hiroshima during World War II.

In the description of the animated image above and the still image underneath NASA said [1

NASA also said:

… the December 18 fireball was the strongest meteor since 2013; However, given the altitude and the remote area over which it occurred, the object did not pose a threat to the ground. Fireball events are quite common and are recorded in the database of the NASA Center for Near-Earth Objects.

  Panels show the smoke trail from noon to 02:00.

These individual images were shot every 10 minutes. The Himawari-8 satellite shows the development and the somewhat mysterious color visible in various areas of the Bolide train. The satellite took the first image at 23:50 UTC (23:50 UTC, local time), one or two minutes past the meteor's maximum brightness at 23:48:20 UTC.

Conclusion: On December 18, 2018, satellite instruments recorded images of a large "fireball" – or a bright meteor – exploding the atomic blast over Hiroshima with more than ten times the energy of over the Bering Sea.
