Chi Cygni

Chi Cygni (χ Cyg, χ Cygni) is a variable star of the Mira type in the constellation Cygnus.

Chi Cygni shows one of the largest variations in magnitude known. Typically it brightens and fades from 5th to 13th magnitude. The average period of this brightness fluctuation is 407 days. Observed extremes were 3.3 and 14.3 respectively. Thus Chi Cygni is visible at its minimum only with telescopes larger than 30 centimeters, while at maximum brightness is easily visible to the naked eye. Its distance is approximately 600 light years. The astronomer Gottfried Kirch discovered its variability in 1686.

Thomas Dick, LL.D, writes:

"The period of this star has been settled by Maraldi and Cassini at 405 days; but from a mean of the observations of Mr. Pigot, it appears to be only 392, or at most 396-7/8 days.

"The particulars relating to it are,

Photo of Princess Diana

The magazine came under criticism for publishing a picture of Princess Diana, taken as she was dying. The photo, which is black-and-white, depicts Diana receiving oxygen in the wreckage of the vehicle in which she died on 31 August 1997. The picture, which was also run with black bars across the Princess's face in the British newspaper The Sun, was taken from the book Lady Diana : L'enquete criminelle by Jean-Michel Caradec'h. Despite the criticism, the editor of the magazine defended their decision to publish it.

Qi (state)

Qi (Chinese: 齊; Old Chinese: *[dz]ˤəj) was an ancient Chinese state during the Zhou dynasty of ancient China. Its capital was Linzi (present-day Zibo in Shandong).

Qi was founded around in 1046 BC as one of the many vassal states of the Zhou Dynasty. The first ruler of Qi was Jiang Ziya, the most powerful official during that time. The Jiang family ruled Qi for several centuries before it was replaced by the Tian family in 386 BC. In 221 BC, Qi was the last major state of pre-Imperial China to be conquered by the State of Qin, which became the Qin Dynasty, the first centralized empire of China.

History

Foundation

With the founding of the Zhou dynasty in 1046 BC,King Wu of Zhou assigned the conquered lands as hereditary fiefs to his relatives and ministers. Territory in the area of modern-day Shandong was given to Jiang Ziya, his most important general from which the state of Qi arose. Little information survives from this period. King Yi of Zhou (r. 865–858) attacked Qi and boiled Duke Ai of Qi to death. At the time of King Xuan of Zhou (r. 827–782) there was a succession struggle. During this time many of the native Dongyi peoples were absorbed into the Qi state.
