958 years ago today, Chinese astronomers observed a new star in the constellation of Taurus, which later turned out to be a supernova.
China was able to contribute to the developments in the science of astronomy critically. In their philosophy, the harmony between earth, the sky and humankind were essential, and therefore any disturbance to that balance had to be predicted. This believe caused the astronomers of the historical China a great status, they were able to predict comets like no other culture. Also, the precise predictions were caused by the critical consequences the responsible astronomer had to face in case of a false prognosis.
On July 2, 1839, Sengbe Pieh (later known as Joseph Cinqué) led 53 fellow Africans being transported as captives aboard the Spanish schooner 'La Amistad' from Havana in a revolt against their captors.
