The giant black shadow in the Pacific Ocean is actually the shadow of the Moon shining on Earth when an eclipse occurs.
The black shadow shone on the Pacific Ocean with a large area close to Australia.
On March 9, 2016, Japan's weather satellite encountered a black shadow about 4,800km wide, traveling at 3,200km / h on the Pacific surface, according to the Science Channel. The reason is that that day happened an eclipse, the shadow of the Moon shining on Earth with a large area nearly equal to Australia.
